ROCKS AND ROCK CYCLE

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of transformation of rocks from one type to another, including igneous, sedimentary, and metamorphic rocks.

Front

What are igneous rocks?

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.

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things, often formed through weathering.

Front

What is clastic sedimentary rock?

Back

Clastic sedimentary rock is formed from fragments of other rocks that are compacted and cemented together.

Front

What is organic sedimentary rock?

Back

Organic sedimentary rock is formed from the remains of once-living plants and animals, such as coal and limestone.

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.
