Match the Plate Tectonics term/key idea with it's description.

Pay attention to the names of the terms. They often offer BIG hints towards their meaning!

Column A
1.
The rise of hot less dense magma and the fall of cooler, more dense magna in the asthenosphere creates this process:
2.
Animal Fossils that were found on several different continents, that could not have swam the ocean to get there.
3.
Tropical Plant fossil found in Antarctica that suggests the climate of Antarctica has changed from tropical to arctic!
4.
The name of the process that creates new ocean crust at the Mid-Ocean Ridge::
5.
Wegener's unsupported Theory that the continents were all one big landmass, and then moved apart to present day.:
6.
The name of the Supercontinent:
7.
Plate boundary that collides together:
8.
Plate boundary that separates:
9.
Conservative Plate boundary that doesn't create landforms, but just slides past each other:
10.
Two oceanic plates collide, resulting in this string of volcanoes out in the middle of the ocean:
11.
Point underground where an Earthquake originates.:
12.
Point on the surface, directly above where the earthquake originated. This is where the magnitude is felt the most.
13.
Theory that explains why the Continents have moved: Convection in the asthenosphere have moved the plates in the lithosphere
14.
In a convergent boundary between two crusts of different densities, the more dense crust will sink down. This is called_____________
15.
When oceanic crusts subduct under another crust, this DEEP landform in the ocean is created. If you flew above it, it would be a dark line in the water.
16.
Geologist and Naval officer Harry Hess discovered the longest underwater mountain range when he was looking for enemy submarines during World War II. He named it the _________________________:
17.
A plate boundary that results in Earthquakes is called a _________________ (San Andreas has a famous one...)
18.
Hawaii was made from one of these, where magma plumes upward through the middle of a plate, instead of seeping out at a plate boundary.
19.
A study of ocean floor rocks, and how the iron and nickel alignment suggest the Earth's poles have reversed several times.
20.
Convergent boundary of two continental crusts (with similar density) uplift to form this landform. Ex: Himalayas and Appalachians!
