Weathering and Erosion
Wildcard
100

The outermost/thinnest layer of the earth. Made up of loose materials like rocks, soil, and seabed.

What is the crust?

100
Solid sections of rock that float on earth's molten mantle.
What are tectonic plates?
100
Earthquakes are an example of this type of change (slow/rapid)
What is a rapid change.
100

This type of erosion usually causes deltas to form.

What is water erosion?

100

A earthquake and a volcano are examples of this type of process (slow/quick)

What is quick?

200
This layer makes-up about 85% of earth's mass.
What is the mantle?
200

The place where the plate comes together is called this.

What is plate/fault lines?

200
This is what magma is called when it reaches earth's surface.
What is lava?
200
This kind of weathering breaks down materials with acid.
What is chemical weathering?
200
These usually occur in an area known as the "ring of fire."  Bonus* explain why?

What are earthquakes and/or volcanoes. This occurs because this is an area where many plates come together.

300
The innermost layer of the earth.
What is the inner core?
300

Scientist use these to study plants an animals from the past. Bonus* Where are they found?

What are fossils? They are found in the layers of the earths crust.

300
These occur when tectonic plates rub against one another.
What are earthquakes?
300
This kind of weathering breaks down materials through forces like friction.
What is physical weathering?
300

A deep canyon (like the Grand Canyon) is usually formed by this type of erosion.

What is water erosion?

400
The first 50 miles of this layer are hard rock, the next 150 miles are molten rock.
What is the mantle?
400

A canyon or mountain forming is an example of what type of change? (slow or quick)

What is a slow change?

400
Volcanoes occur when this bursts out of earth's crust.
What is magma?
400
This process moves materials that have been broken down through weathering.
What is erosion?
400

The name for the dirt/broken down material that gets eroded by wind and water.

What is sediment?

500
Because of extremely high pressure, the iron and minerals that make-up this layer of the earth cannot melt.
What is the inner core?
500

This happens when plates push together and one gets submerged or both rise.

What is mountains form?

500
This state was created by volcanoes.
What is Hawaii?
500

A sand dune, or mushroom rock are formed by this type of erosion.

What is wind erosion?

500

A scientist will not whine about a problem to determine a solution, but he will a_______e it.

What is analyze?
