Rocks and Minerals Review

What has to be present in order for metamorphic rocks to form?

• Melting and Cooling

• Heat and Pressure

• Weathering and Erosion

• Compaction and Sedimentation

What type of rock is formed by the cooling of magma?

• Sedimentary rock

• Metamorphic rock

• 
  Igneous rock

• Clastic rock

Which of the following correctly lists the steps of sedimentary rock formation?

• Particles are compacted and cemented into new sedimentary rock. → High heat and pressure compact large rocks into sediments. → Particles are compacted and cemented into new sedimentary rock.

• Wind and water move and help the sediment particles collected. → High heat and pressure compact large rocks into sediments. → Particles are melted and cooled into new sedimentary rock.

• High heat and pressure compact large rocks into sediments. → Particles are compacted and cemented into new sedimentary rock. → Wind and water move and help the sediment particles collected.

• Weathering and erosion break down large rocks into sediment. → Wind and water move and help the sediment particles collected. → Particles are compacted and cemented into new sedimentary rock.

What is the Mohs hardness scale used to figure out?

• the shape of the mineral

• the color of the mineral's streak

• which minerals reflect the most light

• which minerals can scratch other minerals

Lana is comparing two minerals by shining a bright light on them and seeing how much is reflected off. What is Lana measuring?

• color

• streak

• luster

• hardness

The picture shows a mineral being tested.

Which mineral property is being tested in the picture?

• color

• hardness

• streak

Choose the picture that shows a mineral.

The picture shows an object.

Which of the following best describes the object?

• a rock, because it is made up of different minerals

• a mineral, because it is made up of different rocks

• a rock, because it is made up of only one kind of mineral

• a mineral, because it is made up of only one kind of rock

A diamond is a 10 on the Mohs hardness scale. What will happen when a diamond is scraped against a mineral with a lower hardness rating?

• The diamond will chip.

• The diamond will increase in hardness.

• The diamond will scratch the other mineral.

• The diamond will lose hardness to the other mineral.

How are rocks and minerals identified?

• Rocks are identified by their color, and minerals are identified by their size.

• Rocks are identified by how they were formed, and minerals are identified by the structure of their crystals.

• Rocks are identified by where they are found, and minerals are identified by how they were formed.

• Rocks are identified by where they are found, and minerals are identified by how they were formed.
