What is the mantle?
The scientist that came up with the Theory of Continental Drift
Who is Alfred Wegener?
The term used to describe the way plates move and relate to each other.
What is: plate boundary?
What is: divergent?
Which three plates meet in the Indian Ocean?
What is: The Arabian, Eurasian, and Indian Plates?
Pangaea was a landmass around this many years ago.
The phrase used to describe the breaking apart of Pangaea and the ongoing movement of land masses.
What is continental drift?
Define a divergent boundary.
The plate boundary found in the Pacific Ocean between the United States and Russia.
What is a convergent plate boundary?
Three effects of the movement of plates.
What are:
- Creation and eruption of volcanoes
- Earthquakes
- New land masses formed
- Creation of mountains and islands
- New ocean/continent shapes

This period occurred around 65 million years ago.
What is: Cretaceous?
Name at least TWO pieces of supporting evidence for the Theory of Plate Tectonics.
What are:
- Fossils of similar animals and plants found on different continents
- Shapes of the continents can be pieced together like a puzzle
- Rocks in mountain ranges in different continents match each other
The term used to describe when two plates slide past each other.
What is: transform boundary?
Name three features near the Nazca Plate.
What are:
- Galapagos Hot spot
- Convergent Boundary
- Divergent Boundary
- Easter Island Hot Spot
True/False: Plate boundaries move land masses a few feet each year.
Name a rift valley.
What is: African Rift Valley,
The definition of a tectonic plate.
What is: Huge slabs of rock that move along the mantle?
The term used to describe the plate that sinks below another at a convergent plate boundary.
What is: subduction plate.
The San Andreas fault indicates that this area experiences...

Describe how a mid-ocean ridge forms.
What is: When magma rises through oceanic crusts, cools, hardens, and pushes older rock to the side?
Describe the connection between moving plates and volcanoes.
What is: Plate movement causes volcanoes to form and erupt. Conversely, volancoes form where these plates move apart, meet, and even in the middle of them!
