What causes weathering and erosion?

Back

Natural forces such as wind, water, and ice cause weathering and erosion.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, transformation, and destruction.

Front

What is the role of time in rock formation?

Back

Time allows for the processes of weathering, erosion, and sedimentation to occur, leading to the formation of new rocks.

Front

What is an example of a sedimentary rock?

Back

An example of a sedimentary rock is limestone.
