Rock Types and the Rock Cycle

Front

What is a metamorphic rock?

Back

A metamorphic rock is a type of rock that has been changed from its original form due to heat, pressure, or chemically active fluids.

Front

What process transforms sandstone into quartzite?

Back

The process of metamorphism transforms sandstone into quartzite through heat and pressure.

Front

What is the role of weathering and erosion in the rock cycle?

Back

Weathering and erosion break down rocks into smaller particles, which can then be transported and deposited to form sedimentary rocks.

Front

What is regional metamorphism?

Back

Regional metamorphism is the process where rocks are altered over large areas due to high pressure and temperature, often associated with tectonic activity.

Front

What sedimentary rock is transformed into marble?

Back

Limestone is the sedimentary rock that is transformed into marble during metamorphism.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.

Front

How do igneous rocks form?

Back

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is sedimentation?

Back

Sedimentation is the process by which sediments settle out of a fluid, such as water or air, and accumulate to form sedimentary rocks.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including melting, cooling, erosion, and sedimentation.
