Unit 3 & 4 Review

Front

What is weathering?

Back

Weathering is the process by which rocks are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

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, water, or ice.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids (liquids and gases), which can create high and low pressure systems in the atmosphere.

Front

What happens when high and low pressure systems meet?

Back

When high and low pressure systems meet, they can lead to stormy weather and precipitation.

Front

What is the stratosphere?

Back

The stratosphere is the second layer of Earth's atmosphere, located above the troposphere, and is known for containing the ozone layer.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of Earth's atmosphere, where weather occurs and where we live.

Front

What is the mesosphere?

Back

The mesosphere is the layer of the atmosphere above the stratosphere, where temperatures decrease with altitude.

Front

What is the thermosphere?

Back

The thermosphere is the layer of the atmosphere above the mesosphere, characterized by very high temperatures and the presence of ionized gases.

Front

What is sedimentation?

Back

Sedimentation is the process by which particles settle out of a fluid, forming layers of sediment.
