Question 8
8.

Click and drag each item to the corresponding category. (Items may be used more than once or not be used at all.)

  • creation of new crust
  • San Andreas Fault
Question 9
9.

Describe how a 'Strike-Slip Fault' is different from a 'Transform Fault'.

Question 10
10.

What is the name of the process of one tectonic plate going under another?

Question 11
11.

Oceanic Crust and Continental Crust converge.

Which goes under, and why?

Question 12
12.

Why does the top of the continental crust deform and fracture in a subduction zone?

Question 13
13.

The crust melting from the subducting plate causes magma to 'float up' to the surface and create volcanoes.

Question 14
14.

What is the driving force behind the movement of the tectonic plates?

Question 15
15.
When oceanic and oceanic plates converge, the __________ plate tends to subduct because it is often the one with the __________ density.
Question 16
16.

Check off anything that makes the following statement true.

When continental and continental plates converge ...

Check all boxes that complete the statement.

Continental crust is...

Oceanic Divergent
Continental Divergent
Transform
translation
tranformation
neither plate is dense enough to go into the mantle
neither technically 'subducts'
they typically form volcanoes
they create a melange of rock
Aleutian Islands
