Rock Cycle

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes how rocks change from one type to another over time through processes like melting, cooling, erosion, and compaction.

How does magma become an igneous rock?

Back

Magma becomes an igneous rock through the process of cooling.

Front

What type of rock is most likely to contain fossils?

Back

Sedimentary rocks are most likely to contain fossils because they form in layers that help preserve them.

Front

What type of igneous rock forms from lava that cools quickly on the Earth's surface?

Back

Extrusive igneous rock forms from lava that cools quickly on the Earth's surface.

Front

What type of rock is formed when heat or pressure changes an existing rock?

Back

Metamorphic rocks are formed when heat or pressure changes an existing rock.

Front

Where are the oldest layers of sedimentary rock typically found?

Back

The oldest layers of sedimentary rock are typically found towards the bottom.

Front

What is the process called when sediments are pressed together to form sedimentary rock?

Back

The process is called compaction.

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 erosion in the context of the rock cycle?

Back

Erosion is the process by which rocks and soil are worn away and transported by natural forces such as wind or water.

Front

What role does heat play in the formation of metamorphic rocks?

Back

Heat can cause existing rocks to change their structure and mineral composition, leading to the formation of metamorphic rocks.
