B) They can rub the minerals together to see if one will scratch the other.
C) They can shine light on the minerals to see how much light they reflect.
D) They can rub the minerals on something hard to see what color streak they leave.
D) They can rub the minerals on something hard to see what color streak they leave.

A scientist wants to find out what type of mineral she has. What is the best way for her to find out?
A) She could look at the color, hardness, and luster.
B) She could look at the weight, hardness, and color.
C) She could look at the color, weight, and size.

Granite is an igneous rock and is formed by what processes.
A) Heat and Pressure
B) Melting (molten magma) and Cooling
C) Weathering, Erosion, Deposition, Compaction, and Cementation
B) Melting(molten magma) and cooling
Granite is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
400
Which of these would be the least useful when identifying a mineral?
A) luster
B) hardness
C) shape
D) color
C) shape
400
This rock is found in places that have volcanos?
A) sedimentary rock
B) metamorphic rock
C) igneous rock
C) Igneous Rock
Are igneous rocks always formed by volcanoes?
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
