Rocks and minerals are extracted from the earth through a process called
Mining
Are the preserved remains of plants and animals that were once living on Earth

Is used to describe how rocks are formed, how they break apart, and how they reform into other rocks
Marble is an example of which type of rock?
Metamorphic

Where are rocks found?
Everywhere!
What is one mineral that if often extracted from streams of water?
Gold
Is a measure of how resistant a material is to being scratched
Hardness
This type of mining is done by scraping soil away from the earth’s surface
Surface Mining
For fossilization to occur, remains must be covered in small pieces of rock called:
sediment
What are the three types of rocks?
Igneous, Sedimentary, & Metamorphic
The hardest mineral on the Moh’s Scale is:
Describes how light interacts with the surface of an object (shiny or dull)
Lustre
This type of mining happens when miners go underground into a mine shaft
Underground Mining
How long does the fossilization process take?
About 10,000 years
Sedimentary
The softest mineral on the Moh’s Scale is:
Talc
Streak
This form of mining is when minerals are extracted from rivers
Panning
Is the study of the earth’s history based on fossils
