Front

What type of rock is formed from the accumulation of sediments?

Back

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

Front

What is the process called when rocks are broken down into smaller pieces?

Back

Weathering is the process by which rocks are broken down into smaller pieces by water, wind, ice, and temperature changes.

Front

What type of rock is formed from molten magma that cools and solidifies?

Back

Igneous rock is formed from molten magma that cools and solidifies.

Front

What does extrusive mean in relation to igneous rocks?

Back

Extrusive igneous rocks are formed from lava that cools quickly on the Earth's surface.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly underground, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are changed by heat, pressure, or chemically active fluids.

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 erosion?

Back

Erosion is the process by which sediments are transported from one location to another by water, wind, or ice.

Front

What role does compaction play in sedimentary rock formation?

Back

Compaction is the process that squeezes sediments together, reducing the space between them and forming sedimentary rock.
