Rock Transformations - Pre-Unit Assessment 8th

Front

What are the two main types of rocks based on their formation processes?

Back

Igneous rocks and sedimentary rocks.

Front

How do igneous rocks form?

Back

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

Front

What is sedimentary rock primarily composed of?

Back

Sedimentary rock is primarily composed of small pieces of rock, minerals, and organic material that have been compacted and cemented together.

Front

Can sedimentary rock transform into igneous rock? If so, how?

Back

Yes, sedimentary rock can transform into igneous rock if it is subjected to high temperatures and pressures, causing it to melt into liquid rock.

Front

What role does energy play in the formation of different rock types?

Back

Energy from Earth's interior can melt rock into liquid rock, forming igneous rock, while energy from the sun can weather rock into small pieces, forming sedimentary rock.

Front

What is the process called when one tectonic plate moves beneath another?

Back

Subduction.

Front

What happens to a tectonic plate during subduction?

Back

The subducting plate sinks into the mantle and can lead to melting and the formation of magma.

Front

What is the significance of plate tectonics in the formation of rocks?

Back

Plate tectonics explains how rocks can be formed, transformed, and recycled through processes like subduction, melting, and sedimentation.

Front

What is the difference between magma and lava?

Back

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

Front

What is weathering in the context of rock formation?

Back

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