What does lithosphere mean?
The lithosphere is is the upper mantle of the earth.
100
Name a characteristic of a p-wave.
It's the fastest earthquake wave. It travels through solids and liquids. Travels through the planet. Travels paralel to the direction of motion.
100
What is a caldera
a large depression on a volcano.
100
what is continental drift 
it's an idea where earth's continents drifted from one landform called pangea 
100
why does uniformitarianism require such a long time 
because earth has to be way older than previously thought to explain earth's geological landmarks
200
What is below the lithosphere?
The asthenosphere.
200
Describe a normal fault
The foot wall goes above the hanging wall.
200
What is the difference between the vent and the throat of a volcano.
The vent releases the lava, and the throat pushes it up.
200
what proof has been found supporting this theory 
they found the same dinosaur bones in to different places

Name one catastrophic thing caused by and earthquake?

Describe the mantle.
The mantle is the thickest layer and is made from hard rock.
300
Explain how an earthquake will affect earths surface.

300
Name a characteristic of a shield volcano
broad mountain with gently sloping flanks, erupts runny lava, produces quiet eruptions, forms at hot spots.
300
explain seafloor spread
there is a magnetic field on the seafloor that pules the continents apart
300
What's a reverse fault?
It is where the hanging wall goes above the foot wall.

What's the difference between a cinder cone and a composite.

A cinder cone is a cone shaped mountain that has steep flanks and at the summit it has a bowl shaped crater. A composite is a large mountain with steep sloping flanks

400

What's the density of the oceanic crust?
3.3 g/cm cubed
