Front

What is weathering?

Back

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

Front

What role does ice play in weathering rocks?

Back

Ice can cause weathering by freezing and expanding in cracks of rocks, which eventually breaks the rocks apart.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

How does gravity affect the motion of a baseball after it is hit?

Back

Gravity affects the baseball's motion at all times until it comes to a stop, pulling it down toward the ground.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

How can you compare the friction of sandpaper and ice?

Back

You can compare their friction by testing how easily objects slide over each surface.

Front

What is an aquifer?

Back

An aquifer is a layer of porous rock that can hold and transmit water underground.

Front

How is water stored in an aquifer?

Back

Water is stored in an aquifer as a liquid in the spaces of porous rock.

Front

What is a contact force?

Back

A contact force is a force that occurs when two objects are in physical contact with each other.

Front

What is the effect of friction between a ball and a table?

Back

Friction between the ball and table slows down the ball as it rolls.
