4.4 Rock Transformations Unit Assessment

Front

What is the role of energy in rock formation?

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

Can igneous rock form from sedimentary 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

How does wind and rain affect rock?

Back

Wind and rain interact with rock, breaking it into small pieces, which can lead to the formation of sand.

Front

What is gneiss?

Back

Gneiss is a type of metamorphic rock that forms when existing rocks are heated and put under pressure.

Front

Can sedimentary rock form from igneous rock?

Back

Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is metamorphic rock?

Back

Metamorphic rock is formed from existing rock that has been changed by heat, pressure, or chemically.

Front

What is igneous rock?

Back

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

Front

What is weathering?

Back

Weathering is the process by which rocks are broken down into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind or water.
