Lesson 3: Rocks and Minerals

Question 1

rock that is hot
enough to the point of being
molten

Answer 1

Magma

Question 2

igneous rock that forms within crust; centuries – millions of years to form

Answer 2

Intrusive

Question 3

igneous rock that forms above surface; seconds to years to form

Answer 3

Extrusive

Question 4

Part of bedrock exposed at the

surface.

Answer 4

Outcrop

Question 5

The smaller particles from the rocks after
weathering, erosion, transportation, and deposition
process

Answer 5

Sediments

Question 6

Unless they are moved, they will be buried by

more sediments. At depths of hundreds of meters, they are compressed and cemented.

Answer 6

Sedimentary rocks

Question 7

Rocks that are buried deeper and heated up, squeezed

Answer 7

Metamorphic rocks

Question 8

the process of bringing material buried under the surface onto the surface

Answer 8

Uplift

Question 9

Getting material into deeper depths

Answer 9

Burial

Question 10

Process involved in breaking

down rocks and transferring to another place until it settles in a place

Answer 10

Weathering, erosion, transportation, and deposition

Question 11

Come from magma

Answer 11

Igneous rock

Question 12

Can form from metamorphic rocks

Answer 12

Magma

Question 13

Can come from any kind of rock as long as they are buried deep enough to experience great temperature and pressure

Answer 13

Metamorphic rock

Question 14

Inorganic materials and occur as solids

Answer 14

Minerals

Question 15

Minerals are arranged in a certain form (referred to as its _)

Answer 15

lattice

Question 16

The color of the mineral in its powdered form

Answer 16

Streak

Question 17

Not the most reliable way to describe minerals by itself

Answer 17

Color

Question 18

The way a mineral reflects light

Answer 18

Luster

Question 19

Measure of ability to scratch or be scratched by another.

Answer 19

Hardness

Question 20

It is used to determine how hard a

mineral is by scratching it against reference minerals.

Answer 20

Moh’s Scale of Hardness

Question 21

The way a mineral breaks along a plane easily and smoothly based on its lattice.

Answer 21

Cleavage

Question 22

The mineral’s plane of breakage

Answer 22

Cleavage plane

Question 23

The way a mineral will break if there are no cleavage planes.

Answer 23

Fracture

Question 24

Mass/Volume of a mineral.

Answer 24

Density

Question 25

the density multiplied by g (9.81) to transform mass into

weight.

Answer 25

Specific Gravity
