100
This is the name of the proposed "supercontinent" where all the earth's continents were once joined together.
What is Pangaea?
100
Seafloor Spreading occurs at what type of plate boundary?
What is a divergent boundary?
100
This is the underlaying (plastic-rock) flowing layer which allows the earth's plates to move.
What is the Asthenosphere?
100
This type of plate boundary involves two plates moving apart from one another.
What is a divergent boundary?
100
These features are produced on earth when two continents (continental plates) collide.
What are mountains?
200
This is the meteorologist who first proposed the Theory of Continental Drift
Who is Alfred Wegener?
200
This is where seafloor spreading occurs.
What are mid-ocean ridges?
200
This is the rigid upper layer of the earth which includes the earth's crust and upper most mantle.
What is the lithosphere?
200
This type of plate boundary involves two plates moving toward each other.
What is a convergent boundary?
200
These features are produced on the coasts of continents where oceanic crust moves underneath the continent.
What are volcanoes or volcanic arcs?
300
This is how many years ago earth's "supercontinent" began to split apart.
What is 200-250 million years ago?
300
This ocean is currently growing in size due to seafloor spreading.
What is the Atlantic Ocean?
300
What causes the tectonic plates to move?
Convection Currents
300
This type of plate boundary involves one plate sliding past another plate.
What is a transform boundary?
300
These natural disasters occur when a sudden movement occurs along transform boundaries.
What are earthquakes?
400
What are the four types of evidence that were used to support the Theory of Continental Drift.
What are fossil evidence, glacial evidence, continent fit evidence and landforms evidence?
400
This is the name for the marks on rocks caused by glaciers.
What are striations?
400
Name the layers of Earth from the outside to the inside.
What are the crust, the mantle, the outer core and the inner core
400
This is the term for one plate being forced underneath another plate.
What is Subduction?
400
This is the name of fault found in California where several major earthquakes have occurred.
What is the San Andreas Fault?
500
Give the example for the landform evidence for Continental Drift theory
What are the coal fields in Europe and North America
500
Name the evidence that supported Hess' theory.
What are drilling samples, molten material, and magnetic stripes.
500
Name the two types of crust found on earth and their composition.
What is continental crust made up of granite and oceanic crust made up of basalt
500
Name the term for a break in Earth's crust where rocks have slipped past each other.
What is a fault?
500
Of the three collisions that may occur, which one does not involve subduction?
continental and continental
