Three types of Rocks

Front

What is a nonfoliated metamorphic rock?

Back

A type of metamorphic rock where the mineral grains are arranged randomly, without any visible layers.

Front

What is a foliated metamorphic rock?

Back

A group of metamorphic rocks that have visible layers or bands of minerals within them.

Front

What is compaction in geology?

Back

The process that presses sediments together, reducing their volume and increasing their density.

Front

In which type of rock can you find fossils?

Back

Fossils are typically found in sedimentary rocks.

Front

What is needed for a metamorphic rock to form?

Back

Heat and pressure are required for the formation of metamorphic rocks.

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 sediments, often containing fossils.

Front

What is the rock cycle?

Back

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

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 soil and rock are removed from one location and transported to another by natural forces.
