Plate Tectonics
Rock Cycle
Mining
Weathering and Erosion
100
Are distribute unevenly around the globe.
What elements and/or minerals?
100

In this type of plate boundary the plates slide horizontally.  These boundaries are often responsible for earthquakes.

What are transform boundaries?

100
Solid chemical substances with uniform structures that form under specific temperatures and pressures.
What are minerals?
100

This law regulates mining processes and attempts to minimize the effect of mining on the environment.

What is surface mining control and reclamation act

100

The mechanical breakdown of rocks and minerals

What is physical weathering?

200

This sphere of the Earth contains all the organisms both currently alive and previously alive

What is the biosphere

200

This is the name of the supercontinent that included nearly all land on the current continents

What is Pangea

200
These rocks form directly from magma
What are igneous rocks?
200
The type of mining where miners remove the top of a mountain with explosives.
What is mountaintop removal?
200
The breakdown of rocks and minerals by chemical reactions, the dissolving of chemical elements from rocks, or both.
What is chemical weathering?
300

These a minerals that are good conductors of electricity and are shiny.

What are metallic minerals?

300
The process where oceanic plates meet continental ones. The old oceanic crust is pulled down beneath the continental lithosphere, and the heavier oceanic plate slides underneath the lighter continental plate.
What is seafloor spreading?
300
Form when sedimentary rocks or igneous rocks are subjected to high temperatures and pressures.
What are metamorphic rocks?
300
The process of looking for metals and precious stones in river sediments.
What is placer mining?
300
Physical removal of rock fragments from a landscape or ecosystem
What is erosion?
400

Composed of several layers- each layer has a different density and is made of different minerals.  This is the layer were minerals form.

What is the geosphere?

400
This is made by a plate moving over a geologic hot spot.
What is a volcano?
400

An example of this type of rock is slate

What is a metamorphic rock?

400

This is the process of returning mined land to the original state or better. 

What is reclamation

400

More of this will cause an increase in the rate of erosion of an ecosystem

What is more precipitation and higher temperature

500

These are 2 spheres are most directly impacted when a forest fire occurs. 

What are the biosphere and the atmosphere. 

500

This is likely the greatest human hazard of plate tectonic movement

What are earth quakes

500

This type of rock may contain fossils and is caused from weathering and compaction. 

What is sedimentary rock?

500
The most dangerous type of mining for humans to work with
What is subsurface mining?
500

More of this will decrease the rate of erosion in an ecosystem

What is vegetation?
