Rock Transformations: Chapter 2

Front

What is the process by which all rocks on Earth's surface can weather and become sediment?

Back

Weathering is the process that breaks down rocks into smaller pieces, which can then become sediment.

Front

How does energy from different sources affect the formation of different rock types?

Back

Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, while energy from the sun causes rock to weather into small pieces.

Front

What do we call the process of sediment being pressed and glued together?

Back

Compacting and cementing.

Front

What is matter?

Back

Anything that has mass and takes up space.

Front

Can sedimentary rock change into igneous rock?

Back

Yes, if sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.

Front

What is the main source of energy that causes weathering of rocks?

Back

The sun is the main source of energy that causes weathering of rocks.

Front

What is the difference between igneous rock and sedimentary rock?

Back

Igneous rock forms from the cooling and solidification of molten rock, while sedimentary rock forms from the accumulation and compaction of sediment.

Front

What role does heat and pressure play in rock transformation?

Back

Heat and pressure can change sedimentary rock into metamorphic rock.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface.
