Science 8: Chapter 4 Lesson 1

Front

What is the main classification method used by geologists for rocks?

Back

Geologists classify rocks based on how they form.

Front

Do igneous rocks form as a result of erosion, deposition, compaction, and cementation?

Back

No, igneous rocks form from the cooling and solidification of magma or lava.

Front

How can sedimentary rocks form?

Back

Sedimentary rocks can form when water evaporates and minerals crystallize.

Front

What is compaction in the context of rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, not related to temperature or fluids.

Front

Can each rock type follow only one pathway in the rock cycle?

Back

No, each rock type can follow multiple pathways in the rock cycle.

Front

What are the three main types of rocks?

Back

Igneous, sedimentary, and metamorphic.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process where rocks are formed, broken down, and reformed.

Front

What is an igneous rock?

Back

Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava).

Front

What are sedimentary rocks primarily composed of?

Back

Sedimentary rocks are primarily composed of particles from other rocks, minerals, and organic materials.

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are changed by heat, pressure, or fluids.
