• Soil conservation
• Deposition
• Abrasion
• Erosion

When all the grains in a rock are large and easy to see, the rock is described as _____.

• Extrusive
• Fine grained
• Coarse grained
• Non-banded

When all the grains in a rock cannot be seen without the help of a microscope, the rock is described as _____.

• Non-banded
• Coarse grained
• Fine grained
• Extrusive

The process by which sediment settles out of the water or wind carrying it is _____.

• Erosion
• Deposition
• Cementation
• Compaction

Heat and pressure deep beneath Earth's surface can change any rock into _____.

• Chemial rock
• Gemstones
• Metamorphic rock
• Sedimentary rock

In which type of rock would you most likely find fossils?

• Sedimentary Rock
• Igneous Rock
• Metamorphic Rock
• Angiedaddy's Rock

Sedimentary Rocks are formed by __________ that have ________________ together

• sediments, compacted and cemented

• sediments, melted

• lava, melted

• sediments, gone through metamorphosis

_____________ are formed when _______________ cools and solidifies.

• Igneous rocks, lava or magma

• Metamorphic rocks, sediment

• Igneous rocks, sediment

• Metamorphic rocks, lava or magma

Could the material for igneous rock come from sedimentary rock?

• Yes, if sedimentary rock is exposed to energy from the sun at Earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock.

• 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.

• No, igneous rock can only form from other igneous rocks. Sedimentary rock cannot change into igneous rock.

• No, igneous rock forms under Earth’s outer layer due to energy from Earth’s interior, but sedimentary rock only forms at Earth’s surface.

How does metamorphic rock form?

• It was heated and put under pressure.

• It broke into sediment and then compacted.

• It melted and cooled.

• Rocks don’t form; they stay as they are.
