Rock Cycle Review

Front

What type of weathering is caused by animal actions?

Back

Mechanical Weathering: This type of weathering occurs when animals, such as burrowing creatures, break down rocks into smaller pieces.

Front

What are examples of chemical weathering?

Back

Chemical Weathering: Includes processes like dissolution, hydrolysis, hydration, oxidation, and acid rain that change the chemical composition of rocks.

Front

What are the three major types of rocks?

Back

Igneous, Metamorphic, Sedimentary: These are the three main categories of rocks based on their formation processes.

Front

Which rock is formed from the cooling of volcanic ash on Earth's surface?

Back

Extrusive Igneous Rock: This type of rock forms when lava cools quickly on the Earth's surface, often resulting in a fine-grained texture.

Front

What is the process called when rocks break into smaller pieces due to exposure to natural elements?

Back

Weathering: This is the process that breaks down rocks into smaller fragments through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion: The process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is sediment?

Back

Sediment: Small particles of rock and soil that are transported by wind, water, or ice and can accumulate in layers.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive Igneous Rocks: Formed from magma that cools slowly beneath the Earth's surface. Extrusive Igneous Rocks: Formed from lava that cools quickly on the surface.

Front

What is metamorphism?

Back

Metamorphism: The process by which existing rocks are transformed into metamorphic rocks through heat, pressure, and chemical processes.

Front

What is the rock cycle?

Back

The Rock Cycle: A continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic.
