Rocks & Minerals Test Review

How is Igneous Rock formed?

• Compaction & Cementation

• Extreme heat & pressure

• Melting, cooling & hardening

• Weather, erosion & deposition

Determine the hardness of Mystery Mineral #1 using the data below.

• Mystery Mineral has a hardness between 1 & 2.

• Mystery Mineral has a hardness between 4 & 5.

• Mystery Mineral has a hardness between 6 & 7.

• Mystery Mineral has a hardness between 2 & 3.

A student is creating a model to show the process of how rocks are formed. She gets the tiniest of pebbles. Uses a cup to make layers of pebbles and glue and then she smashes the layers down as much as possible.

The student is modeling the formation of which rock?

• Igneous Rock

• Magma Rock

• Sedimentary Rock

• Metamorphic Rock

Luster is a physical property that can be used to identify minerals. How can luster be described?

• The color of the powder of a mineral

• The way the surface of mineral reflects light

• The color of a mineral

• The scratch resistance of a mineral

Using the rock cycle diagram. What processes are taking place in between Igneous Rock and Sediments?

• Melting and cooling

• Weathering and erosion

• heat and pressure

• compacting and cementing

• Weathering and erosion

How is Metamorphic Rock Formed?

• Cooling and hardening

• Cementing and compacting

• Extreme heat and pressure

• Weathering & erosion

Which statement about the formation of rocks is true?

• Heat and pressure can change igneous rock to sedimentary rock

• Weathering and erosion can change igneous rock into sediments.

• Heat and pressure can cause metamorphic rock to weather and erode

• Weathering and erosion can cause magma to change into igneous rock.
