What are the three types of boundaries and draw arrows to show how they move?
Boundaries are Convergent (-----><------) Divergent (<----- ----->) Transform. -------> <------

What is the name for Wegener's supercontinent?
Pangaea
200
What happens at a transform boundary?
Earthquakes.
200
What layer is made up of solid iron and nickel?
Inner Core
200
The linear surface along which rocks break and slide past each other is called what?
A fault.
200
What are the two types of volcanoes?
Shield and stratovolcano.
200
What causes tectonic plates to move?
Convection currents in the Earth's mantle.
300
What happens when two continental plates converge?
Mountains are built.
300
What two layers are made up of fluids?
Outer core and the mantle
300
What is the scientific name for the location where an earthquake occurs?
Epicenter
300
What is a volcano?
A break in the earth's surface where magma and other materials escape from the Earth's interior.

Wegener theorized that all of the continents were one large landmass at one time but have drifted into their current places. List the four pieces of evidence for his theory.
1. Fossils (same species, opposite sides of the ocean) 2. Continents fit together like puzzle pieces 3. Climate evidence (glaciers and coal) 4. Rock types (same rocks, opposite sides of the ocean)
400
What happens when an oceanic plate and a continental plate converge?
1. Subduction of the oceanic plate 2. Creation of volcanoes
400
What are the two types of crust?
Oceanic and continental
400
What are seismic waves used for?
To figure out the location of an earthquake.
400
What explodes from a stratovolcano?
Gas, ash, and light igneous rocks.
400
What is the name of this theory. "The growth of oceanic crust at the mid-ocean ridge as magma escapes through weak sections of the crust."
Seafloor spreading.
500
Where do you find a divergent boundary in the ocean?
Mid-ocean ridge.
500
What layer do tectonic plates float on?
The mantle
500
Which type of seismic waves travels fastest?
Primary or P-waves.
500
What is the shape of a shield volcano?
Shallow slope and not very tall.

Coal has been found in Antarctica beneath the ice. How is this possible? Explain you answer using the theory of Continental Drift.
All the continents use to be one large landmass and have now drifted to there current place. Antarctica use to be in the tropics, near the equator.
