Cooling and solidification.

Front

What is erosion?

Back

The geological process in which earthen materials are worn away and transported by natural forces such as wind or water.

Front

How are sedimentary rocks primarily formed?

Back

By deposition and compaction of sediments.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from cooling magma, while sedimentary rocks form from the accumulation and compaction of sediments.

Front

What is the rock cycle?

Back

The continuous process of rock formation and transformation, including igneous, sedimentary, and metamorphic rocks.

Front

What is weathering?

Back

The breaking down of rocks and minerals through natural processes such as wind, water, and temperature changes.

Front

What is deposition?

Back

The geological process where sediments are laid down in new locations after being transported.

Front

What are metamorphic rocks?

Back

Rocks that have been changed from their original form due to heat and pressure.
