Unit 12: Rock Cycle

What does the color of a mineral refer to?

• The color of the mineral when it is wet

• The appearance of the color on the surface of the entire mineral

• The color of the mineral when it is broken into pieces

• The color of the mineral under ultraviolet light

What is a streak in terms of mineral properties?

• The color of the mineral in powdered form when mixed with water

• The color of the mineral when it is heated

• The color of powder left behind when the mineral is scratched

• The color of powder left behind when rubbed on a streak plate

Why should one be careful when identifying minerals by color alone?

• The color of the mineral can change when exposed to sunlight

• The color of the mineral can be different from the streak color

• The color of the mineral can be the same for all minerals

• The color of the mineral can fade over time

What does the term "luster" refer to in mineral properties?

• The color of the mineral

• How light reflects off the surface of the mineral

• The weight of the mineral

• The smell of the mineral

Which scale is used to measure the hardness of minerals?

• Richter Scale

• Mohs Hardness Scale

• Beaufort Scale

• Saffir-Simpson Scale

What is the hardness of a mineral that can scratch calcite but not fluorite according to Mohs Hardness Scale?

• 3

• 4

• 5

• 6

Which of the following objects has a hardness just below diamond on the Mohs Hardness Scale?

• Steel Nail

• Copper Penny

• Masonry Drill Bit

• Fingernail

What type of luster would a mineral have if it reflects light like glass?

• High/Metallic Luster

• Low/Glassy Luster

• Dull Luster

• Pearly Luster

What is density defined as in the context of physical properties of matter?

• The amount of space an object occupies.

• The amount of mass in an object per unit of volume.

• The amount of weight an object has.

• The amount of surface area an object covers.

How is density calculated?

• Density = Mass + Volume

• Density = Mass / Volume

• Density = Mass x Volume

• Density = Volume / Mass
