Continental Drift
Who first proposed the idea of continental drift?
Alfred Wegener
Which layer of Earth's interior is slowly drifting over time?
Lithosphere ( Crust )
This type of plate boundary creates mountain ranges.
Convergent: Continental/Continental
Which type of volcano has steep sides and a small opening, often being the most dangerous volcanoes?
Stratovolcano or Composite Volcano
Which Hot spot can be found in the Continental United States?
Yellowstone Hot Spot
What was the first and weakest piece of evidence used to support the theory of continental drift?
The continents appear to be able to fit together like puzzle pieces.
Which process drives plate tectonic motion?
Convection
Which type of plate boundary is responsible for Earthquakes?
Transform
This type of volcano has very broad slopes and is often not very active?
Shield Volcano
What type of plate boundary runs along the West coast of South America?
Convergent
Which two continents were the fossils of Mesosaurus found?
South America and Africa
The layer in which convection occurs is know as what?
Asthenosphere
The Mid Atlantic Ridge spans the entire length of the Atlantic Ocean and is an example of this type of boundary
Divergent
The Hawaiian Islands are the result of a stationary magma plume known as a ________ ________.
Hot Spot
What is the density of Oceanic Crust?
3.0 g/cm3
What is the name of the plant fossil that linked multiple continents together?
Glossopteris
Describe why convection can happen in the Asthenosphere
Because this layer is partially melted and behaves like plastic.
This term describes one plate overriding another that sinks back into the mantle.
Subduction
A small hill like formation made from ejected volcanic material is better known as what?
Cinder Cone
Name the boundary that is responsible for Earthquakes on the West Coast of the US
San Andreas Fault
What is the name of the Supercontinent that existed before they drifted apart?
Pangea
At roughly what rate do tectonic plates move?
2 to 10 cm per year
Which factor will cause one plate to sink back into the mantle in a convergent boundary?
That plate has a high density
Lava can flow at different rates due to this factor regarding its consistency
Viscosity
Which plate is the Hawaiian hot spot found ?
The Pacific Plate
