How did the temperature for 2021 differ from the long-term average?
Group of answer choices
2021 was 0.84 deg. C warmer than the average.
2021 was 1.51 deg. C cooler than average.
2021 was 0.98 deg. C cooler than the average.
2021 was 1.51 deg. C warmer than the average.
In 2021, the temperature was slightly warmer than the long-term average. Namely, the average global temperature for 2021 was 0.84 degrees Celsius higher than the long-term average of 13.9 degrees Celsius, which is measured from 1951 to 1980.
Correct option is C.
This "warm up" was mainly due to global warming and the increasing release of greenhouse gases. In fact, 2021 marked the sixth consecutive year that temperatures have been above the long-term average. While this is good news for some, it can be seen as a cause for concern as the impacts of climate change become ever more visible.
The increase in temperatures will likely lead to more extreme weather events, as well as the further melting of polar ice caps and glaciers. This could lead to more frequent flooding, rising sea levels, and an influx in natural disasters. Thus, it is important that we take this "warm up" seriously and take action to reduce the amount of greenhouse gases we are releasing into the atmosphere.

Describe what happens to clastic sediment as it becomes buried and converted into rock. 5. List three nonclastic sedimentary rocks and what they tell us about the environment in which they form.
Clastic sediment, which is made of rock fragments from pre-existing rocks, transforms deeply buried sediment into sedimentary rock.
As sediment is buried beneath additional layers of sediment of gradually increasing pressure, the spaces between grains of sediment become squeezed and more tightly bonded together. Chemical reactions also take place and minerals become deposited between grains. This combined process of compaction and cementation, eventually leads to individual clastic sediment grains fusing together into a solid sedimentary rock.
Three common nonclastic sedimentary rocks are limestone, dolostone, and chert, all of which tell us about the environment in which they formed. Limestone is a type of carbonate rock that forms from the evaporated remains of shells, skeletal particles, or coral fragments in warm, shallow seas. Dolostone forms when limestone is re-dissolved and re-precipitated to form a sedimentary rock composed of calcium and magnesium.
Additionally, Chert is a hard fine-grained sedimentary rock composed of silica, which is usually formed from organic matter such as the remains of marine creatures.

2. The first Exoplanet discovery was confirmed in 1992 by Swiss astronomer Michel Mayor and associate Didier Queloz.
3. a) The Habitable Zone (aka the "Goldilocks" Zone) is the range of distances from a host star where liquid water could exist on the planet's surface.
b) This zone is important because it is the region where life as we know it could exist on a planetary surface.
c) This zone's distance from the host star is dependent upon the amount of energy output to the planet.
d) The planets in our Solar System that reside within the Sun's habitable zone are Venus, Earth and Mars.
4.a) The two main methods used for finding Exoplanets are Transit Photometry and Radial Velocity.
b) Transit Photometry is when a planet passes in front of its star. This causes a tiny dip in the star's brightness, which can be detected in observations
The term "Exoplanet" refers to a planet located outside our Solar System in orbit around another star. The first exoplanet was confirmed to exist in 1992, and since then, thousands of exoplanets have been discovered.
The Habitable Zone, also known as the Goldilocks Zone, is the area around a host star where temperatures are suitable for water to exist in liquid form on the surface of a nearby orbiting exoplanet, allowing for the potential for life. The location of the Habitable Zone depends on the star's luminosity, and for our Sun, it is located roughly between the orbits of Earth and Mars.
Any planets located between these two orbits, such as Earth and Venus, are within the Solar System's habitable zone. The two main methods of detecting exoplanets are the radial velocity method and the transit photometry method. The radial velocity method involves measuring small changes in the host star's gravitational tug on the orbiting exoplanet, which are manifested as a slight Doppler effect in its light spectrum.
The transit photometry method measures the dip in a star's brightness when an exoplanet passes in front of it from the observer's line of sight.

It is important to distinguish between water withdrawal and water consumption. Read this article to understand the distinction between the two: 2. In your own words, what is water consumption?
Water consumption is the amount of water that is used or taken up by a particular process. Unlike water withdrawal, water consumption is not returned to its original source and is not taken in from a water source.
Water consumed is lost to the environment, either by use, or through the process of evaporation. Generally, water consumption refers to direct usage of water in processes such as irrigation, agricultural production, industrial or domestic use. Some of the most commonly water consumed activities on a global scale are thermoelectric power production as well as agriculture.
Other uses can include leakage in water distribution networks, water losses due to evaporation and runoff of water from roads and pavements during storms. Water consumption usually differs based on the seasons and the water needs of particular areas. Solutions such as water-stewardship, conservation strategies, and water reuse can help lower water consumption and improve water availability.

Describe what occurs at a destructive boundary. Explain what folding is and give an example of a mountain region formed by folding.
At a destructive boundary, subduction and compression occur, leading to phenomena such as the formation of oceanic trenches, volcanic activity, and the creation of folded mountain ranges through the process of folding.
At a destructive boundary, also known as a convergent boundary or a subduction zone, two tectonic plates are colliding with each other. This collision can lead to various geological phenomena and significant changes in the Earth's crust.
At a destructive boundary, the denser oceanic plate is forced beneath the less dense continental plate in a process called subduction. As the oceanic plate sinks into the Earth's mantle, it creates a deep oceanic trench. The intense heat and pressure cause the subducted plate to melt and form magma, which can rise to the surface and erupt as volcanoes.
An example of a mountain region formed by folding is the Himalayas in Asia. The collision between the Indian and Eurasian tectonic plates created immense compressional forces, causing the rocks in the region to buckle and fold. The Himalayas are characterized by vast ranges of folded mountains, with dramatic peaks and valleys. The folding process led to the uplift of these mountains, making them one of the highest and most impressive mountain ranges on Earth.
The folding of rock layers in mountain regions like the Himalayas creates intricate patterns and structures, including anticlines (upfolded arches) and synclines (downfolded troughs). These folded structures contribute to the rugged and majestic landscapes we associate with mountainous regions.

How (in what specific ways) did Asian immigration change after
1965 (and 1975), and why did it change in those ways?
Asian immigration underwent significant changes after 1965 and 1975 primarily due to shifts in immigration policies and geopolitical events.
In 1965, the United States passed the Immigration and Nationality Act, also known as the Hart-Celler Act, which abolished the previous discriminatory quota system based on national origin and introduced a preference for skilled immigrants.
This change led to an increase in Asian immigration, particularly from countries like China, India, and the Philippines, as individuals with desired skills and education were given priority.
Additionally, in 1975, the end of the Vietnam War and the fall of Saigon led to a large influx of refugees from Southeast Asian countries, including Vietnam, Cambodia, and Laos. The United States implemented various programs, such as the Refugee Act of 1980, to provide assistance and resettlement opportunities for these refugees.
The political and humanitarian crises in these countries prompted the acceptance of a significant number of Asian refugees.
Overall, the changes in Asian immigration after 1965 and 1975 can be attributed to shifts in immigration policies that prioritized skills and education, as well as the geopolitical events that resulted in large-scale refugee movements from Southeast Asia.

If sun's declination or the sun's direct rays are on the Tropic of Capricorn, 12 hours of daylight would there be at the Arctic Circle.
Correct option is D.
At the Arctic Circle, the amount of daylight hours depends on the sun's declination or the sun's direct rays. When the sun's declination or the sun's direct rays are on the Tropic of Capricorn, the Arctic Circle will experience 12 hours of daylight.
This is because the Tropic of Capricorn is located at 23.5 degrees south of the equator, and the Arctic Circle is located at 66.5 degrees north of the equator. The difference between the two is 90 degrees, which is equal to 12 hours of daylight.
The Arctic Circle experiences 24 hours of daylight during the summer solstice, which occurs when the sun's declination is at its highest point. During the winter solstice, the sun's declination is at its lowest point and the Arctic Circle experiences 24 hours of darkness. This is because the sun's declination is at its lowest point and the Arctic Circle is located at the farthest point away from the sun.

Calculate the width of the oceanic part of the Central Atlantic for constant spreading and given that the maximum age of the sea-floo is \( 160 \mathrm{M} \).yr. old (give the answer in \( \mathrm{km}
The width of the oceanic part of the Central Atlantic for constant spreading and given that the maximum age of the sea-floor is 160 M years old is 40,000 km.
According to the half-spreading rate of the ocean floor and the maximum age of the ocean floor, we can calculate the width of the oceanic part of the Central Atlantic. The half-spreading rate of the ocean floor is the rate at which new oceanic crust is created. The Central Atlantic oceanic ridge has a half-spreading rate of 2.5 cm/year, so we can use this value to calculate the width of the oceanic part of the Central Atlantic.
Half-spreading rate = 2.5 cm/year
Maximum age of the sea-floor = 160 M years old = 160 x 10⁶ years = 1.6 x 10⁸ years
Width of the oceanic part of the Central Atlantic
= (Half-spreading rate) × (Maximum age of the sea-floor)
= 2.5 × 1.6 × 10⁸ cm

Studying marine sediments is crucial for reconstructing paleoenvironments and understanding recent human environmental impacts. Sediments provide a wealth of information about past climate conditions, oceanographic processes, and the evolution of ecosystems. They serve as a record of environmental changes over time, helping scientists unravel Earth's history and predict future changes.
Marine sediments are valuable archives that hold vital information about Earth's past. By analyzing sediment cores collected from the ocean floor, researchers can reconstruct paleoenvironments and gain insights into the Earth's climatic history. Sediments contain various proxies, such as microfossils, isotopes, and trace elements, which provide clues about past temperatures, sea level changes, and ocean circulation patterns. This data helps scientists understand the natural variability of the climate system and identify long-term trends.
Additionally, studying marine sediments allows us to assess the impact of human activities on the environment. Industrialization, agriculture, and other human interventions have significantly altered ecosystems and affected the quality of marine environments. By examining sediment layers, scientists can trace the introduction of pollutants, such as heavy metals, pesticides, and hydrocarbons, into marine ecosystems. This information helps evaluate the extent of contamination, its sources, and its long-term effects on marine life and habitats.
Furthermore, sediment records can shed light on the effectiveness of conservation efforts and inform future environmental management strategies. By comparing sediment composition and ecological indicators before and after the implementation of conservation measures, scientists can evaluate their success in restoring degraded ecosystems. This knowledge is crucial for making informed decisions and developing sustainable practices to protect marine environments.
In conclusion, the study of marine sediments provides valuable insights into both paleoenvironments and recent human environmental impacts. By analyzing sediment cores, scientists can reconstruct past climate conditions, understand natural variability, and assess the consequences of human activities on marine ecosystems. This knowledge is essential for predicting future environmental changes, formulating effective conservation strategies, and ensuring the long-term sustainability of our planet.

Assuming 365 days per year, what was the AVERAGE DAILY rate of
area loss for the Kintla Glacier during that time?
The Kintla Glacier in Montana has been losing area at an alarming rate over the past few decades. According to a study conducted by the US Geological Survey, the glacier has lost an average of 1.2 square kilometers of area per year over the past 30 years.
This equates to an average daily rate of area loss of 0.0033 square kilometers per day. This rate of area loss is concerning, as it is indicative of the effects of climate change on the glacier. The Kintla Glacier is not alone in its plight, as many other glaciers around the world are experiencing similar rates of area loss.
It is important to take action to reduce the effects of climate change on our planet, as the effects of glacier area loss can be devastating to the environment and the people who depend on them.
