Click on the flashcard to see the answer


What are the three main types of rocks?

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

Which type of rock is formed from the cooling and solidification of magma or lava?

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

Which type of rock is formed from the deposition and compaction of sediments?

Sedimentary rocks are formed from the deposition and compaction of sediments.

Which type of rock is formed from the transformation of existing rocks through heat and pressure?

Metamorphic rocks are formed from the transformation of existing rocks through heat and pressure.

What are some examples of igneous rocks?

Examples of igneous rocks include granite, basalt, and obsidian.

What are some examples of sedimentary rocks?

Examples of sedimentary rocks include limestone, sandstone, and shale.

What are some examples of metamorphic rocks?

Examples of metamorphic rocks include marble, slate, and quartzite.

How are igneous rocks classified?

Igneous rocks are classified based on their texture and composition.

How are sedimentary rocks formed?

Sedimentary rocks are formed through weathering, erosion, deposition, compaction, and cementation.

How do metamorphic rocks form?

Metamorphic rocks form through the heat and pressure applied to existing rocks.

What is the rock cycle?

The rock cycle is a continuous process that describes the formation, breakdown, and reformation of rocks.

What is weathering?

Weathering is the process of breaking down rocks into smaller particles.

What is erosion?

Erosion is the process of transporting and removing weathered materials from one location to another.

What is deposition?

Deposition is the process of laying down or depositing sediments in a new location.

What is compaction and cementation?

Compaction is the process of squeezing sediments together, and cementation is the process of binding them into solid rock.
