Rock Cycle

Front

What are organic sedimentary rocks?

Back

Rocks made from the remains of once-living plants or animals.

Front

What is non-foliated texture in rocks?

Back

A texture where mineral grains grow and rearrange but do not form layers.

Front

What type of igneous rock is formed from magma cooling at or near Earth’s surface?

Back

Extrusive igneous rock, which has small grains.

Front

What process can flatten mineral grains in rocks without melting them?

Back

Pressure.

Front

What is formed when temperature and pressure are great enough to melt rock?

Back

Magma.

Front

What are the three main types of rocks in the rock cycle?

Back

Igneous, sedimentary, and metamorphic rocks.

Front

How are igneous rocks formed?

Back

By the cooling and solidification of magma or lava.

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive rocks form from magma that cools slowly beneath the surface, while extrusive rocks form from lava that cools quickly on the surface.

Front

What are clastic sedimentary rocks?

Back

Rocks formed from the accumulation of fragments of other rocks.

Front

What is the role of weathering in the rock cycle?

Back

Weathering breaks down rocks into smaller particles, which can then form sediment.
