Magmatic Differentiation describes the formation of one or more secondary magmas from a single parent magma.

Magmatic differentiation refers to the process in which a single parent magma undergoes physical and chemical changes, leading to the formation of multiple secondary magmas with different compositions. During magmatic differentiation, as the parent magma cools and solidifies, certain minerals may crystallize out of the melt, altering the remaining liquid's composition.

This process can occur due to factors such as differences in cooling rates, changes in pressure, or the presence of volatile substances. As a result, the remaining liquid can become enriched or depleted in certain elements or minerals, leading to the formation of different secondary magmas. The secondary magmas may have distinct chemical compositions, mineral assemblages, and eruptive behaviors compared to the original parent magma.

Magmatic differentiation plays a vital role in generating the diverse range of igneous rocks found on Earth and contributes to the variability observed in volcanic eruptions and volcanic rock formations.

Indirect detection is the condition in which an extra-solar planets cannot be observed but its presence is deduced from the activity of its host star. Direct detection occurs when the exoplanet is observable through a telescope.

In order to find extrasolar planets, astronomers have typically had to use indirect techniques. As of 2016, a variety of indirect detection has been successful. By analyzing the impacts the planet has on its parent star, scientists deduce its presence rather than actually finding the planet.

Compared to the distances between stars, the extrasolar planet's separation from its star is extremely small. The light reflected from any extrasolar planet circling a star similar to the sun is approximately a billion times brighter than the star itself. Due to diffraction, telescopes also distort starlight. Since their parent stars are significantly brighter than our sun, extrasolar planets are just too close to them to be directly observed from interstellar distances.

For a set of sedimentary rocks that are folded in a syncline, the oldest rocks are found in the center of the syncline.

A syncline is a type of fold in which the layers of rock dip downward to form a trough-like structure. The oldest rocks are found at the bottom of this trough, as they were the first to be deposited on the sea floor or other sedimentary environment.

As new layers of sediment were deposited on top of the older layers, the weight of the overlying sediment caused the layers to compress and fold into the syncline structure. The rocks on the outer edges of the syncline are younger, as they were deposited later and have been folded over the older rocks.

Therefore, geologists can use the position of rocks within a syncline to determine their relative ages and the order in which they were deposited.

d. the age of one feature with respect to another within a sequence of events and deduced from the positions of rock strata above and below one another.

Relative age refers to the age of one geological feature relative to another within a sequence of events. It is determined by examining the positions of rock strata in relation to one another. The principle of superposition states that in an undisturbed sequence of rock layers, the youngest rocks are found on top, and the oldest rocks are found at the bottom.

By observing the relative positions of different rock layers, geologists can establish a relative age relationship. This allows them to create a chronological order of events and assign approximate ages to geological features based on the period or epoch in which they occurred.

Relative age dating does not provide specific numerical ages but instead focuses on the relative order of events and the relative ages of rocks and features within a given geological context.

True. The large, lava-covered areas on the Moon are indeed called maria.

The term "maria" (singular: mare) is derived from Latin, meaning "seas." However, despite their name, maria are not actual bodies of water but vast basaltic plains formed by ancient volcanic activity. These dark, flat regions on the Moon's surface are visible to the eye and were mistaken for bodies of water by early astronomers. The maria were created by volcanic eruptions billions of years ago when magma from the Moon's interior flooded the low-lying areas and solidified into basalt. They are characterized by their relatively smooth texture compared to the heavily cratered highlands surrounding them. Today, the maria serve as important landmarks for lunar observations and studies.

For cyclogenesis to occur along a frontal wave, the winds aloft directly above the wave should be diverging or moving away from each other.

Cyclogenesis is the process by which a cyclone or low-pressure system forms and intensifies. One way that cyclogenesis can occur is along a frontal wave, which is a boundary between two air masses with different temperatures and moisture content. As the wave moves along the boundary, it can create areas of convergence and divergence in the wind patterns, which can trigger cyclogenesis.

In order for cyclogenesis to occur along a frontal wave, the winds aloft directly above the wave should be diverging or moving away from each other. This divergence creates an area of low pressure at the surface, which can intensify and become a cyclone. The degree of divergence is related to the strength of the low-pressure system and the rate at which it intensifies.

The divergence of winds aloft is caused by a number of factors, including the presence of an upper-level trough or jet stream that causes the winds to diverge as they move around it. Other factors include the location and intensity of high-pressure systems, which can also affect the wind patterns and trigger cyclogenesis. By monitoring these factors, meteorologists can predict the likelihood of cyclogenesis along a frontal wave and issue weather advisories and warnings accordingly.

During the 1960s, the City of Vancouver, Canada attempted to improve the Downtown Eastside (DTES) neighborhood through a variety of urban renewal and social welfare initiatives.

Here are some of the key efforts made by the city during this time:

Urban Renewal: The city launched several urban renewal projects in the DTES during the 1960s, aimed at improving the physical infrastructure of the neighborhood. These included the construction of new social housing projects, such as the Strathcona Gardens development, and the expansion of community services like the Carnegie Community Centre.

Zoning Changes: The city implemented new zoning regulations in the DTES to try to limit the number of hotels and rooming houses in the area. The goal was to reduce the concentration of poverty and improve the overall livability of the neighborhood.

Social Welfare Programs: The city also invested in a range of social welfare programs during the 1960s, aimed at improving the quality of life for DTES residents. These included increased funding for mental health and addiction services, as well as the creation of job training and employment programs.

Policing: The city also increased its policing presence in the DTES during the 1960s, with the goal of reducing crime and improving public safety. This included the creation of a new police precinct in the neighborhood and the implementation of new policing strategies.

While some of these initiatives were successful in the short term, many have been criticized for their negative impacts on the DTES and its residents over the long term. For example, the urban renewal projects often involved the displacement of low-income residents and the destruction of historic buildings and cultural landmarks, while the increased policing presence led to a disproportionate targeting of marginalized communities. Today, the City of Vancouver continues to grapple with the complex social and economic issues facing the DTES and its residents.

Changes in topography, water chemistry, and gas output all are used to help predict a) volcanic eruptions.

Changes in topography, water chemistry, and gas output are all important indicators used in monitoring and predicting volcanic eruptions. Here's how these factors play a role:

Topography: Monitoring changes in the shape and elevation of the volcano can provide valuable information. Swelling or deformation of the volcano's surface, measured using techniques like GPS and satellite-based interferometry, can indicate the movement and accumulation of magma beneath the surface. Bulges, fissures, or changes in the volcano's shape may suggest increased volcanic activity and the potential for an eruption.

Water Chemistry: Monitoring changes in water chemistry, particularly in geothermal areas or volcanic lakes, can provide insight into volcanic activity. Rising magma can interact with groundwater or surface water, leading to changes in the composition and temperature of the water. An increase in the concentration of certain chemicals, such as sulfur compounds or volcanic gases, can serve as a precursor to an eruption.

Gas Output: Volcanoes emit various gases, including sulfur dioxide (SO2), carbon dioxide (CO2), hydrogen sulfide (H2S), and others. Monitoring changes in the amount and composition of volcanic gases can help assess volcanic activity. Increasing gas emissions, particularly sulfur dioxide, can indicate the movement and ascent of magma towards the surface. Gas measurements can be done using ground-based stations, aerial surveys, or satellite-based remote sensing.

By analyzing these indicators along with other monitoring techniques like seismic activity, ground temperature measurements, and volcanic tremors (which could be referred to as harmonic tremors), scientists and volcanologists can gain a better understanding of volcanic behavior and make informed predictions about potential eruptions. These monitoring systems help in assessing the level of volcanic hazard and providing timely warnings to at-risk populations, aiding in mitigation efforts and ensuring public safety.

Overall, the combination of these factors leads to the consistent southeast trade winds between the equator and 30 degrees south.

The winds between the equator and 30 degrees south are known as the trade winds, which blow consistently from the southeast. This is due to a combination of factors, including the rotation of the Earth, the distribution of heat across the planet, and the position of the equator. The Earth's rotation causes the Coriolis effect, which deflects winds to the right in the northern hemisphere and to the left in the southern hemisphere. This means that winds in the southern hemisphere are deflected towards the west, creating a westerly flow. However, the heat distribution across the planet means that the equator receives more direct sunlight, causing warm air to rise and creating a low-pressure area. The air then flows towards the poles, but is deflected to the left due to the Coriolis effect, resulting in the southeast trade winds.

1. Political: Colombia was close to legalizing abortion. Instead, a top court kept restrictions in place

Source: The Washington Post, Date: 3/03/2020

On 2006, Colombian constitutional court ruled abortion was legal in three specific cases: pregnancy resulted from violation, a risk to the mother's life, or fetus malformation. This is more progressive than most Latin American countries jurisdiction; abortion is still outright banned in most Caribbean and Central American countries. It is legal only in Cuba, Uruguay and some Mexican States.

However, there is a wave of change driven by feminist activists in the region. Pro-choice activists argue that poor women find too many barriers to access legal abortion, hence they risk their lives using illegal abortion clinics. Therefore, legal abortion reduces inequality between poor and middle-class women.

Colombian pro-choice activists received a boost when Argentine President announced he intends to issue a bill to legalize abortion. He counts with wide civil society support to pass this bill. This contrasts with a highly divided civil society in Colombia, where the church has a strong influence over policy-making, and where the Colombian president openly opposes abortion.

So, pro-choice activists hoped that the Colombian Constitutional court (which is regarded as a progressive institution) would rule to legalise abortion in the country. Nevertheless, the legalisation of abortion was one vote short to be ruled. According to activist, this is a missing opportunity for the country, to become a leading Latin American Nation in terms of reproductive rights.

2. Economic: UPDATE 1-Colombia tries to calm coronavirus fears, market skeptical

According to Reuters, the finance ministry stated that "(t)he fundamentals of the Colombian economy are still solid and will absorb the described external shocks without severe trauma to financial activity and stability [and] The authorities will take pertinent actions in a coordinated way and the decisions will be announced jointly and when appropriate,”

However, analysts disagree with the government's statement. Crude is the main Colombian export and source of foreign exchange, so after Monday's 10% fall on oil price, the Colombian peso lost 6.29% of its value. Therefore, it is plausible that the Coronavirus impact over the economy could lead the Country to miss the fiscal deficit target of 2.2% of GDP. This failure might lead to a credit rating downgrade for the fourth-largest economy in Latin America.

3. Social: Colombia Is Dealing With a Terrifying Refugee Crisis. Will Wealthy Nations Step Up to Help?

source: The New York Times, 03/10/2020

More than 5million people have fled Venezuela in the past 15 years. This is the largest refugee crisis in Latin America recorded history. Today, it is only comparable to the Syrian refugee crisis. Venezuelans exiles in western countries come from a middle-class professional background. Yet Venezuelans refugees reaching Colombia are in dire poverty conditions, fleeing from violence as well as from hunger, disease and lack of basic necessities. Moreover, Colombia is one of the largest receivers of Venezuelan migrants, and its open border policy contrast with other Latin American nations: Chile and Ecuador are demanding visas from Venezuelan people, Peru is imposing restrictions to migration, and Mexico harasses Venezuelans at border crossings.

Therefore, Colombia is the country that has received the heaviest burden, with thousands of people crossing its border each day. However, Colombia is facing a political crisis of its own, and thousands have rallied against President Duque conservative government during the past months. To attend the crisis, the country is by its own means, and the money simply is not enough. Roughly, each Venezuelan refugee has received about $125. In contrast, the International Community has invested circa $1500 in each Syrian refugee. Given the size of the crisis, Wealthy nations should do more than they are doing to support Colombia and Venezuelans refugees to overcome this crisis.

Explanation:

In the case of the abortion bill, the analysis is focused on the response from the constitutional court, describing the situation as political. The coronavirus impact on Colombia is clearly described from am economical stance. And finally, the Venezuelan refugee crisis is described as a social issue that requires the attention of the international community.

True. Rock flour consists of silt-sized rock and mineral particles that are produced by glacial abrasion.

Glacial abrasion is a process in which glaciers and ice sheets move across the landscape, eroding and wearing down the underlying bedrock. As the ice moves, it acts like a giant file, grinding against the bedrock and breaking it into smaller particles. The resulting debris includes a mixture of fine-grained rock and mineral fragments, often in the form of silt-sized particles.

These silt-sized particles are collectively known as rock flour. They are typically very fine in texture and can range in color depending on the composition of the bedrock being abraded. The process of glacial abrasion is aided by the presence of embedded rock fragments within the ice, which act as cutting tools, further breaking down the bedrock and contributing to the production of rock flour.

Rock flour is often found in glacial environments, particularly in areas with active glaciation or in regions that have experienced glacial activity in the past. It can be transported by meltwater streams and deposited in glacial outwash plains or other landforms associated with glacial processes.

The presence of rock flour has important implications for soil formation, sediment transport, and ecosystem dynamics in glaciated regions.
