ES Chapt 3 Test Rock Cycle

Front

What is an extrusive igneous rock?

Back

An extrusive igneous rock is formed from lava that cools and solidifies on the Earth's surface. Example: Rhyolite.

Front

What is the highest quality type of coal?

Back

Anthracite coal is the highest quality type of coal, known for having the most energy.

Front

What processes change limestone into marble?

Back

Limestone is changed into marble through heat and pressure during the metamorphic process.

Front

What is contact metamorphism?

Back

Contact metamorphism occurs when hot magma forces its way into existing rock, altering its structure and composition.

Front

What type of rock forms when lava cools and crystallizes?

Back

Extrusive igneous rock forms when lava cools and crystallizes.

Front

Define sedimentary rock.

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is the rock cycle?

Back

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

Front

What is metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed by heat, pressure, or chemically active fluids.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is the role of heat and pressure in the rock cycle?

Back

Heat and pressure are crucial in transforming sedimentary rocks into metamorphic rocks.
