December Earth Science Review

Front

What is global warming?

Back

Global warming is the increase of Earth's average surface temperature, primarily caused by the greenhouse effect.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space.

Front

What is ice wedging?

Back

Ice wedging is a process where water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates move towards each other, which can cause earthquakes, volcanic activity, and the formation of mountains.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediments at the mouth of a river, where the river meets a body of water.

Front

What causes an earthquake?

Back

An earthquake is caused by the sudden release of pressure that builds up between two tectonic plates.

Front

What is the Tyndall effect?

Back

The Tyndall effect is the scattering of light by particles in a colloid or in very fine suspensions, which can affect climate by influencing how much sunlight reaches the Earth's surface.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces such as wind, water, and ice.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind or water.
