What is the process where denser plate moves beneath less dense plate?

False. The ocean floor is significantly younger than the centres of continents, according to geologists working in the middle of the twentieth century.

This finding, which showed that the ocean floor is constantly being replenished whereas the continents are considerably older and more stable, was made through the study of seafloor spreading and the formation of a new crust at mid-ocean ridges. This concept is referred to as plate tectonics, a fundamental geological theory that provides an explanation for many of the Earth's geological processes.

Subduction zones occur at convergent plate boundaries where two tectonic plates move towards each other.

Subduction zones occur at convergent plate boundaries where two tectonic plates move towards each other. One plate is usually denser than the other and subducts or sinks beneath the other plate, forming a deep trench. The subducting plate is usually an oceanic plate while the overriding plate can be either an oceanic or a continental plate.

As the oceanic plate subducts, it heats up and melts, forming magma. The magma rises and can trigger volcanic eruptions, leading to the formation of volcanic

Explanation:

The correct answer is option d) rift zones. Rift zones are regions where the continents or the sea floor are pulling apart due to geological forces.

Divergent limits are another name for them. These zones are brought by by molten material rising from the Earth's mantle.

Rift zones are created as this molten material rises and pushes the continental plates apart. Both the ocean floor and the surface of the land include these zones. They frequently take the shape of broad valleys or hills on land. Linear depressions, ridges, and mountains on the ocean floor are signs of rift zones.

The movement of the tectonic plates on Earth results in the creation of rift zones, which is a natural process. The plates diverge as a result of this movement, creating rift zones.

The direction of the wind can change from day to night due to the difference in the heating of the Earth's surface during these times.

During the day, the sun heats the surface of the Earth, causing the air near the surface to warm and rise. This creates an area of low pressure near the surface, which draws in cooler air from surrounding areas. This movement of air is known as convection, and it often results in wind blowing from cooler areas to warmer areas.

At night, the opposite occurs. The surface of the Earth cools down, and the air near the surface also cools and becomes denser. This creates an area of high pressure near the surface, which pushes air away from the surface and toward areas of lower pressure. This can result in the wind blowing in the opposite direction compared to during the day.

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ, such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data,

Let the triangle be ΔABC , where ∠B = 90°

Let the side AB be x

So , the adjacent side = x

The angle of the triangle ∠A is = 72°

So , θ = 72°

Evacuation of a city in advance of a hurricane is an example of an adjustment rather than a prevention strategy.

Prevention strategies are intended to eliminate or reduce the likelihood of a hazardous event occurring. In the case of a hurricane, prevention strategies might include building sea walls, levees, or other types of infrastructure to protect coastal areas from storm surges. Prevention strategies might also involve developing and enforcing building codes that ensure new construction can withstand hurricane-force winds.

On the other hand, adjustment strategies are intended to minimize the impact of a hazardous event that cannot be prevented. In the case of a hurricane, adjustment strategies might include evacuating residents from low-lying coastal areas before the storm hits, stocking up on emergency supplies, and preparing emergency shelters for those who cannot evacuate. These strategies are intended to minimize the loss of life and property damage that can result from a hurricane, even if prevention strategies have been implemented.

Therefore, evacuating a city in advance of a hurricane is an example of an adjustment strategy, as it is designed to minimize the impact of the hurricane and protect human life, rather than prevent the hurricane itself.

The steps involved in fractional crystallization.

1. Magma, after entering through the bottom of the magma chamber, reaches the top of the chamber where temperatures are lower.

2. Magnesium-and iron-rich minerals begin to crystallize

3. Mineral crystals, having a higher density than liquid magma, sink to the bottom of the magma chamber

4. The magma shifts toward a more intermediate composition.

The process of separating two or more crystalline solids based on how differently they dissolve in the same solvent is known as fractional crystallisation. The concentration of the silica that makes up the magma increases its viscosity.

The process of separating liquid from crystals is referred to as "fractional crystallisation." The liquid that remains after this happens is thought to be new magma. There are a number of methods that can be used to separate the crystals from the magma. The compositions of many minerals are denser than those of the liquids from which they crystallize.

can you answer my geo question please

Answer: As an area is impacted by rising sea-level, land subsidence and increase in ocean elevation can cause flooding in areas not previously threatened by high tides. Flooding can occur during exceptionally high tides within annual fluctuations or when strong prevailing winds pile water against the shoreline.

Explanation:

If all the glaciers and ice sheets on Earth were to melt completely, the sea level would rise by approximately 70 meters, or 230 feet.

Glaciers and ice sheets are vast bodies of ice that are found in polar regions, high-altitude areas, and at high latitudes. They are formed over thousands of years as snow accumulates and compresses into dense ice. These ice formations are important for regulating the Earth's climate, and they provide freshwater to many parts of the world.

If all of the glaciers and ice sheets on Earth were to melt completely, the sea level would rise by approximately 70 meters (230 feet). This is because the ice on land contains a huge amount of water - in fact, it is estimated that if all of the ice on Earth were to melt, it would raise the sea level by about 216 feet (66 meters). This would inundate many low-lying coastal areas around the world, displacing millions of people and causing billions of dollars in economic damage.

While it is unlikely that all of the ice on Earth will melt in the near future, the effects of melting glaciers and ice sheets are already being felt. The global sea level has risen by about 8 inches (20 cm) since 1880, and it is projected to rise even more in the coming decades. This is primarily due to the melting of glaciers and ice sheets, as well as the thermal expansion of seawater due to global warming.
