Rocks and the Rock Cycle

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock that forms from sediment that gets cemented or pressed together under pressure.

Front

How are metamorphic rocks formed?

Back

Metamorphic rocks are formed through the process of heat and pressure.

Front

Can a sedimentary rock become an igneous rock?

Back

False. A sedimentary rock can change into an igneous rock through melting and cooling.

Front

What is weathering?

Back

Weathering is the process when rocks break into smaller pieces due to exposure to natural elements.

Front

What are sediments?

Back

Sediments are the particles of weathered rock.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rocks changing from one type to another over time.

Front

What is igneous rock?

Back

Igneous rock is formed from the cooling and solidification of molten rock (magma or lava).

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are rocks that have been changed from their original form due to heat, pressure, or chemically.
