Front

What is the Rock Cycle?

Back

The Rock Cycle is a continuous process where rocks are formed, broken down, and reformed over time. It is always happening.

What happens to a rock during weathering and erosion?

Back

When a rock undergoes weathering and erosion, it breaks down into smaller pieces called sediment.

Front

What are examples of sediment?

Back

Loose pebbles, dirt, and shells are all examples of sediment.

Front

How do you test the streak color of a mineral?

Back

You test the streak color by scratching or dragging the sample across a streak plate.

Front

What type of rock is formed by heat and pressure?

Back

Metamorphic rock is formed when any rock or mineral is subjected to heat and pressure.

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 from the cooling and solidification of molten rock (magma or lava).

Front

What is sedimentary rock made of?

Back

Sedimentary rock is made of particles of sediment that have been compacted and cemented together.

Front

What is the process of turning sediment into sedimentary rock called?

Back

The process of turning sediment into sedimentary rock is called lithification.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces like wind, water, and temperature changes.
