What are intrusive igneous rocks?

Back

Intrusive igneous rocks are types of rocks that form from molten rock (magma) that cools and solidifies beneath the Earth's surface, characterized by large crystal sizes.

What is the process that forms metamorphic rocks?

Back

Metamorphic rocks form from existing rocks that have experienced intense heat and pressure, causing physical and chemical changes.

Front

What is erosion?

Back

Erosion is the process by which running water, wind, or ice carry away bits of broken-up rock.

Front

What is needed for the formation of metamorphic rock?

Back

Existing rock is needed for the formation of metamorphic rock.

Front

How are igneous rocks formed?

Back

Igneous rocks are formed when molten rock cools and solidifies through a process called crystallization.

Front

What are extrusive igneous rocks?

Back

Extrusive igneous rocks are formed from lava that cools and solidifies on the Earth's surface, typically resulting in smaller crystal sizes.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks into smaller pieces, while erosion is the movement of those pieces from one location to another.

Front

What is sediment?

Back

Sediment refers to small particles of rock, minerals, and organic material that are transported by wind, water, or ice.

Front

What is cementation?

Back

Cementation is the process by which dissolved minerals crystallize and glue particles of sediment together, forming sedimentary rock.

Front

What is crystallization?

Back

Crystallization is the process by which molten rock cools and solidifies, forming crystals in igneous rocks.
