Rocks and Rock Cycle

Front

What is sediment?

Back

Sediment is material that comes from rocks that have been broken down into smaller pieces, usually as a result of weathering.

Front

What causes igneous rocks to form?

Back

Igneous rocks form from the cooling of magma or lava and the pressure applied during this process.

Front

What can geologists find in old rocks?

Back

Geologists can find fossils in old rocks.

Front

What is weathering?

Back

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

Front

What type of rock is formed by smaller pieces of rock that settled at the bottom of a lake?

Back

This type of rock is called Sedimentary rock.

Front

What is erosion?

Back

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do sedimentary rocks form?

Back

Sedimentary rocks form from the compaction and cementation of sediments over time.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through various geological processes.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks due to heat, pressure, or chemically active fluids.
