ECB Unit #8 Types of Rock and Rock Cycle

Front

What are the three main types of rocks?

Back

Igneous, Sedimentary, Metamorphic.

Front

How do igneous rocks form?

Back

Igneous rocks form when magma cools and solidifies.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation.

Front

What conditions are necessary for metamorphic rocks to form?

Back

Extreme pressure and heating.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive rocks form underground, while extrusive rocks form on the surface.

Front

What is sedimentary rock made from?

Back

Sedimentary rock is made from fragments of other rocks and minerals.

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks into smaller pieces.

Front

What role does erosion play in the rock cycle?

Back

Erosion transports weathered materials from one location to another.

Front

How does the rate of cooling affect igneous rock texture?

Back

The faster the magma cools, the smaller the crystals in the rock will be.

Front

What is metamorphism?

Back

Metamorphism is the process by which rocks change due to heat and pressure.
