Rock Cycle 6th grade

Front

How do igneous rocks form?

Back

Igneous rocks form when magma or lava cools and hardens.

Front

What causes metamorphic rocks to form?

Back

Metamorphic rocks are formed when heat and pressure cause buried rock to change into new rock.

Front

What is the rock cycle?

Back

The rock cycle is the process by which rocks change into different types of rocks.

Front

What is the process by which igneous rocks are formed?

Back

Igneous rocks are formed through the melting and cooling of lava and magma.

Front

What is weathering?

Back

Weathering is the process by which wind and water change rocks and the Earth's surfaces.

Front

What are the three main types of rocks?

Back

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

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

How does erosion differ from weathering?

Back

Erosion is the process of moving weathered material from one location to another, while weathering is the breaking down of rocks.

Front

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

Back

Pressure causes the minerals in the rock to realign and change, resulting in metamorphic rock.

Front

What is the significance of the rock cycle in geology?

Back

The rock cycle illustrates how rocks are continuously transformed and recycled in the Earth's crust.
