Chapter 4 Rock and the Rock Cycle Review

Front

What is igneous rock?

Back

Rock formed when molten rock solidifies.

Front

What type of metamorphism occurs when ions dissolved in hot water cause chemical changes in a rock?

Back

Hydrothermal metamorphism.

Front

Why is limestone found at the highest point on Earth, Mount Everest?

Back

The limestone formed when the rock that became Mt. Everest was under the sea.

Front

What is extrusive igneous rock?

The continuous process of rock formation, breakdown, and reformation through various geological processes.

Front

What are the three main types of rocks?

Back

Igneous, sedimentary, and metamorphic.

Front

How are sedimentary rocks formed?

Back

Through the accumulation and compaction of sediment.

Front

What is metamorphism?

Back

The process by which rocks are changed by heat, pressure, or chemically active fluids.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

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