Rocks & Minerals Unit Review

Front

What are sediments?

Back

Small particles of rock, minerals, and organic material that are transported by wind, water, or ice.

Front

What are sedimentary rocks?

Back

Rocks formed from the accumulation and compaction of sediments.

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which sediments are moved from one location to another by natural forces such as water, wind, or ice.

Front

What are metamorphic rocks?

Back

Rocks that have been changed from their original form due to heat, pressure, or chemical processes.

Front

What is a mineral?

Back

A naturally occurring inorganic substance with a definite chemical composition and crystalline structure.

Front

What is the significance of crystal size in igneous rocks?

Back

The size of mineral crystals in igneous rocks indicates the rate at which the molten rock cooled; slower cooling results in larger crystals.

Front

What is the rock cycle?

Back

The continuous process of rock formation and transformation, including the formation of igneous, sedimentary, and metamorphic rocks.

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.

Front

What is the role of pressure in the formation of metamorphic rocks?

Back

Pressure can cause changes in the mineral structure and texture of rocks, leading to the formation of metamorphic rocks.
