Rock TYPES

Front

What is the rock cycle?

Back

The rock cycle is a process that changes one type of rock into another type of rock.

Front

What are the three main types of rocks?

Back

Igneous, sedimentary, and metamorphic.

Front

How are all rocks related to one another based on the rock cycle?

Back

All rocks can create any other type of rock.

Front

What process is responsible for the formation of metamorphic rocks?

Back

Metamorphic rocks are formed through heat and pressure.

Front

What are sediments?

Back

Sediments are mud, sand, and tiny bits of rocks that cement together to form a type of rock.

Front

What is an igneous rock?

Back

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

Front

What is a sedimentary rock?

Back

Sedimentary rocks are formed from the accumulation and compaction of sediments.

Front

What is a metamorphic rock?

Back

Metamorphic rocks are formed from existing rocks that are changed by heat, pressure, or chemically.

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 role do weathering and erosion play in the rock cycle?

Back

Weathering breaks down rocks into sediments, and erosion transports these sediments to new locations.
