Earth & Environmental Science

What is the stratosphere?

Back

The stratosphere is the second layer of Earth's atmosphere, located above the troposphere and below the mesosphere. It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

What is the thermosphere?

Back

The thermosphere is the fourth layer of Earth's atmosphere, located above the mesosphere. It is characterized by a significant increase in temperature with altitude due to the absorption of high-energy solar radiation.

Front

What is ozone and why is it important?

Back

Ozone is a molecule composed of three oxygen atoms (O3). It is important because it absorbs the majority of the sun's harmful ultraviolet radiation, protecting living organisms on Earth.

What are convergent boundaries?

Back

Convergent boundaries are areas where two tectonic plates move toward each other, often resulting in one plate being forced below the other, leading to geological features like mountains and trenches.

Front

What are divergent boundaries?

Back

Divergent boundaries are areas where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What are transform boundaries?

Back

Transform boundaries are areas where two tectonic plates slide past each other horizontally. This movement can cause earthquakes.

Front

What is a hot spot?

Back

A hot spot is a location on the Earth's surface that has experienced active volcanism for a long period of time, often resulting from a plume of hot material rising from deep within the mantle.

Front

What is recycling?

Back

Recycling is the process of converting waste materials into reusable materials to reduce waste and preserve natural resources.

Front

What are the environmental benefits of recycling?

Back

Recycling helps preserve raw materials, reduces pollution, saves energy, and decreases the amount of waste sent to landfills.

Front

What are mountain ranges?

Back

Mountain ranges are a series of connected mountains formed by tectonic forces, often found at convergent boundaries where two continental plates collide.
