Volcanoes that occur in the middle of plates and not at plate boundaries are caused by ___________?
Hot Spots
100
What is formed when two continental plates collide?
Mountain ranges are formed.
100
Where are volcanoes most likely to occur?
At or near a plate boundary.
100
Why can't we watch the continents move?
They are moving so slowly, about the rate of fingernail growth.

A Plate Boundary where to plates slide past each other is called a ______________?
Transform Fault Boundary.
200
Much of the land on Earth was formed by __________.
Volcanic Activity.
200
How do the shapes of continents (like S. America and Africa) show evidence for plate tectonics?
The continents fit together like puzzle pieces.
200
Do individual organisms adapt to changes in their environments?
No.
300
The volcano that is forming the Hawaain Islands is caused by ______________?
A Hot Spot
300
What type of plate boundary caused the mid-ocean ridge in the Atlantic between Africa and S. America?
A Divergent Boundary
300
A Transform Fault Boundary results in this type of natural disaster.
Earthquake

What caused/is causing the shape of the land and mountains on Earth?
Plate tectonics
300
What would happen to the fur color of a species of brown rabbits if there was an ice age and they were surrounded by snow and ice?
The fur would evolve to a whiter color.

What type of plate boundary occurs when one plate slide under another plate?
A Subduction Zone
400
What happens when one plate subducts under another plate?
The rock melts under heat and pressure and can rise back to the surface as magma.
400
How long did it take the continents to separate from Pangaea to their current positions?
Millions of years
400
When did life first appear on the Earth?
3.5 Billion Years Ago

500
Which type of boundary produces earthquakes but not volcanoes?
Transform Fault Boundaries
500
Where do most geologic events (like earthquakes, mountain building, and volcanoes) happen here?
At tectonic plate boundaries.
500
The same fossils existing on opposite sides of an ocean are evidence for ____________.
Plate Tectonics
500
How does natural selection lead to evolution?
Beneficial traits help organisms survive and pass on their genes, bad traits die out.
