Rock Cycle

Front

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

Back

Sedimentary rock is formed by the accumulation and compaction of sediments.

Front

What process changes metamorphic rock into sediments?

Back

Weathering and erosion break down metamorphic rock into smaller particles.

Front

What type of rock has grains arranged in parallel bands of white and black crystals?

Back

Metamorphic rock often has a banded appearance due to the alignment of minerals.

Front

What is formed when heat and pressure cause a rock to melt?

Back

Magma is formed when rocks melt due to extreme heat and pressure.

Front

What is the process called when rocks break into smaller pieces due to natural elements?

Back

Weathering is the process that breaks down rocks into smaller fragments.

Front

What are the three main types of rocks in the rock cycle?

Back

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

Front

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of magma or lava.

Front

What is the role of compaction and cementation in the rock cycle?

Back

Compaction and cementation transform sediments into sedimentary rock.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form inside the Earth, while extrusive igneous rocks form on the surface.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things.
