What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic.

Front

How are igneous rocks formed?

Back

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

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed when existing rocks are transformed by heat, pressure, or chemically active fluids.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has reached the Earth's surface.

Front

What process leads to the formation of sedimentary rocks?

Back

Sedimentary rocks are formed through the processes of weathering, erosion, deposition, compaction, and cementation.

Front

What is the role of heat and pressure in the rock cycle?

Back

Heat and pressure can cause existing rocks to change into metamorphic rocks through a process called metamorphism.

Front

What type of rock is formed from the cooling of lava on the Earth's surface?

Back

Igneous rock is formed from the cooling of lava on the Earth's surface.

Front

What is an example of a sedimentary rock?

Back

An example of a sedimentary rock is limestone, which can form from the accumulation of marine organisms' shells.

Front

What happens during the melting phase of the rock cycle?

Back

During the melting phase, rocks are heated to the point where they become molten, forming magma.
