Faults and Folds
What type of fault goes with a divergent boundary?
Tension.
Where is the oldest part of the sea floor spreading?
The outside.
What plate boundary divides?
Divergent.
What is Earth's thinnest layer?
Crust.
An example of a hot spot.
Hawaii islands.
What type of fault goes with a convergent boundary?
Compression.
What causes sea floor spreading?
Convection Currents.
What plate boundary collides?
Convergent.
What layer do convection currents occur in?
The asthenosphere.
True or False: Hot spots are random.
True.
What fold has a downward fold?
Syncline.
Where is the youngest part of the sea floor spreading?
In the middle.
What plate boundary slides?
Transform.
What is the most dense layer?
Inner core.
What is a hot spot?
A hot spot is a large plume of hot mantle material rising from deep within the Earth.
What fault goes with the transform boundary?
Shearing.
What ocean is the sea floor spreading found in?
Atlantic Ocean.
What happens in an oceanic-oceanic boundary?
Seafloor spreading and mid-ocean ridges.
True or False: The lithosphere is the crust and upper mantle.
True.
Where do hot spots occur?
In the mantle.
What fold has a slope downward from the horizontal in the same direction?
Monocline.
When does seafloor spreading occur?
At a divergent boundary.
What happens at an oceanic-continental collision?
Larger earthquakes and higher volcano activity.
What is in the mesosphere?
The lower mantle.
Why do hot spots occur?
Hotspots form over exceptionally hot regions in the mantle.
