Types of Rocks*

Front

What is a nonfoliated metamorphic rock?

Back

A type of metamorphic rock where the mineral grains are arranged randomly, unlike foliated rocks which have a layered appearance.

Front

What does 'coarse' mean in terms of rock texture?

Back

Coarse refers to rocks that have large, easily visible mineral grains.

Front

What type of rock forms from heat and pressure?

Back

Metamorphic rock.

Front

In which type of rock can you find fossils?

Back

Sedimentary rock.

Front

What does 'fine' mean in terms of rock texture?

Back

Fine refers to rocks that have small, barely visible mineral grains.

Front

What are igneous rocks?

Back

Rocks that form from the cooling and solidification of molten rock (magma or lava).

Front

What are sedimentary rocks?

Back

Rocks formed from the accumulation and compaction of mineral and organic particles.

Front

What is the process of metamorphism?

Back

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

Front

What is foliation in metamorphic rocks?

Back

The alignment of mineral grains in a rock, resulting in a layered or banded appearance.

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.
