A mountain is formed from which kind of fault or plate boundary?

Continental Convergent

True or False: Weathering is the carrying away of sediments caused by wind and water?

False, weathering is the process of creating new soil by breaking down rocks into smaller fragments known as sediments.

The cooling of magma or lava
300

What type of boundary causes magma to come through to the surface causing the Mid-Atlantic Ridge?

Divergent Boundary

300

Give an example of PHYSICAL weathering.

-Running Water -Wind -Extreme Heat - Freezing of water between cracks of rocks - Plants growing between cracks in rocks

400
What is the variable that is changed by the experimenter called?
Independent variable
400

What do you call the movement of heat from the core towards the crust?

convection currents

400

How are sedimentary rocks formed?

Sediment compacting and cementing

400

What type of boundary mostly causes earthquakes?

Transform Boundary

400

Give and example of CHEMICAL weathering.

-Rocks destroyed by acid rain -plants produce acids and break down rocks.

Name the 3 main types of boundaries and tell what each do.

Convergent - Plates push toward each other   Divergent - Plates move away from each other. Transform- Plates slide past each other.

What is erosion?

The movement of sediments.
