Front

What is deposition in geology?

Back

Deposition is the process where particles settle as loosely packed sediment.

Front

Where do intrusive igneous rocks form?

Back

Intrusive igneous rocks form underground.

Front

What is the difference between extrusive and intrusive igneous rocks?

Back

Extrusive igneous rocks form from lava that cools quickly on the Earth's surface, while intrusive igneous rocks form from magma that cools slowly underground.

Front

What are sedimentary rocks primarily made of?

Back

Sedimentary rocks are primarily made of particles and sediments that have been compacted and cemented together.

Front

What is the process of sedimentation?

Back

Sedimentation is the process by which sediments settle out of a fluid, such as water or air.

Front

What is the role of weathering in rock formation?

Back

Weathering breaks down rocks into smaller particles, which can then be transported and deposited to form sedimentary rocks.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface.
