Name the four layers of the Earth
Inner core, Outer core, Mantle layer and Lithosphere

What is the name of the last supercontinent?
Pangaea. Scientists believe that the all the continents use to be together because of a lot of evidence such as the related fossils and rocks near the coasts of the continents.
100
What are large mountain ranges caused by? What is an example of them?
-Large mountain ranges are caused by plate convergence, an example of this is the Himalayas
100
What between two plates determines the plate boundary?
the relative motion between the plates
200
Which layer are the tectonic plates located in?
The Lithosphere
200
Who proposed the theory of Continental drift and that the continents separated may have use to be connected?
Alfred Wegener in 1915. Although he was not the first to realize that the continents fit together like a puzzle, he was the first to realize that the continents move over time.
200
What are volcanoes caused by?
Most of the earths volcanos are caused by subduction, which is when two plates converge on one another
200
A boundary where plates slide along each other is called this?
A transform boundary
300
How is a push ridge formed?
A push ridge is formed when molten rock from the mantle layer escapes through cracks in the earth's surface. It then hardens and pushes the land away from it, creating a ridge.

In 1928, Arthur Holmes proposed what could be the driving force to making these ‘plates’ move?
Arthur Holmes proposed that the conventions currents inside the mantle would cause them to move.
300
Why does lava boil up to the surface? What is an example of this?
Lava boiling to the surface is caused by plate separation. An example of this is the Mid-Atlantic Ridge along the Atlantic Ocean where lava boils to the seafloor.
300
What is an example of a Divergent Boundary?
The mid-atlantic ridge
400
The movement pattern in the mantel layer is known as?
A convection cell
400
What are two well-known mountains that were known to form through two plates colliding?
Himalaya and Appalachian mountains are known to be formed this way.
400
What causes an earthquake?
When two plates are shifting and one plate falls lower than the other that is called a fault and is what causes an earthquake
400
Convergent Boundaries can also be called this because of what they form.
Destructive boundaries
500
Explain two ways the tectonic plates move?
Tectonic plates move because of the movement of molten rock in the mantle layer, and also because of changes in temperature which cause the lithosphere to swell or sink.
500
What did Arthur Holmes compare thermal convection to be like?
A conveyor belt
500
What small plate located near the United States causes most volcanoes in the area?
The Juan de Fuca plate, located on the Northwest part of the United States is largely responsible for the volcanoes that occur there
