What are the three main types of rocks?

Back

Igneous, Sedimentary, Metamorphic.

Front

How are igneous rocks formed?

Back

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

Front

What is sedimentary rock made of?

Back

Sedimentary rock is made of particles of sand, silt, clay, and organic materials that have been compacted and cemented together.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that have been changed by heat, pressure, or chemical processes.

Front

What is the process of weathering?

Back

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

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often by water, wind, or ice.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation, involving igneous, sedimentary, and metamorphic rocks.

Front

What role does heat play in the formation of metamorphic rocks?

Back

Heat causes changes in the mineral structure of existing rocks, leading to the formation of metamorphic rocks.

Front

What is cementation in the rock cycle?

Back

Cementation is the process where dissolved minerals crystallize and glue particles of sediment together to form sedimentary rock.

Front

What type of rock is formed from volcanic activity?

Back

Igneous rock is formed from volcanic activity when magma cools and solidifies.
