Ch. 3 Rocks and the rock cycle

Front

What is the rock cycle?

Back

The rock cycle is the continuous process by which rocks are formed, broken down, and transformed into different types of rocks over time.

Front

What are the three main types of rocks?

Back

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

Front

How are igneous rocks formed?

Back

Igneous rocks are formed by the cooling and solidification of magma or lava.

Front

What is sedimentary rock made of?

Back

Sedimentary rock is made of small pieces of rock, minerals, and organic materials that have settled and compacted over time.

Front

What is metamorphic rock?

Back

Metamorphic rock is rock that has been changed from its original form due to heat, pressure, or chemical processes.

Front

Can sedimentary rocks become igneous rocks?

Back

Yes, sedimentary rocks can become igneous rocks through processes like melting and cooling.

Front

What determines the crystal size in igneous rocks?

Back

The crystal size in igneous rocks is determined by how quickly the magma or lava cools.

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks into smaller pieces by natural forces like wind, water, and ice.

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often by water, wind, or ice.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the Earth's surface, while lava is magma that has reached the surface.
