Q

What kind of rock forms when minerals dissolve in a crystalize dewater solution

A

Chemical rock

15
Q

A rock that forms another rock as a result of heat and pressure

A

Metamorphic

16
Q

Where are metamorphic rocks found?

A

In mountains near masses of igneous rock

17
Q

What are ways that metamorphic rocks form

A
  1. While Lava pockets rise through the crust its heat temperature can change rock to metamorphic
  2. pressure can form metamorphic rock, deeper the rock is the more pressure on the rock
18
Q

How are metamorphic rocks classified

A

According to The arrangement of the grains that make up the rock

19
Q

Metamorphic rock that have parallel lines or bands of grains

A

Foliated rocks(slate)

20
Q

Non foliated rocks(marble or quartzite)

A

Grains in rocks are randomly arranged

21
Q

What are marble and slate used for

A

Building and sculpting
