What are the four other volcanic landforms?
What are Calderas, Neck & pipes, Lava plateaus, and Plutons?
200
What are the four pieces of evidence that Alfred Wegner used to prove his hypothesis?
What are continental shape, matching fossils, rock types & structures, and ancient climates?
200
What are the 3 types of plate boundaries?
Divergent, Convergent, and Transform Fault.
200
what are the 2 types of lava flows?
What are Aa lava, and Pahoehoe?
200
what are the 3 types of volcanos?
What are Shield volcano, Cinder cone, and Composite cones?
200
What causes a caldera to form?
When a magma chamber empties and collapses in on itself.
300
What is the large land mass that is known as the super continent?
What is Pangaea?
300
What is which plate boundary moves past each other?
What is Transform Fault?
300
If a volcano erupts violently and the lava flows as fast as water, how high is the viscosity?
The viscosity would be very low.

What is an effect of a stratovolcano?
What are Lahars?
300
What is an example of Necks & Pipes?

400
Why did Wegener's hypothesis get rejected?
Wegener couldn't explain how the continents were moving.
400
What are the three Mechanism of plate motion?
What are Slab-pull, Mantle convection, and Ridge-push?

What are Lava flows, Gases, and Pyroclastic materials?
400
Which volcano created Mt. Fugi?
What is Composite Cones or Stratovolcanoes?
400
What causes Neck & Pipes?
When the magma cools in the vent of a volcano and the mountain around it erodes away.
