How many estimated tectonic plates are there along the surface of the Earth?
There are about 20 plates.
What is an epicenter?
An epicenter is the location directly above the earthquake on the surface of the earth.
Where do tectonic plates move and what is the motion?
They mainly move in the mantle by convection.
How many quakes were in the New Madrid Earthquakes.
There were about 1,874 different quakes.
How does the density affect the movement of plates.
More density will make the earthquakes rise and less will make it sink.
What is a Fault?
A Fault is an area of stress in the earth where broken rocks slide past each other
What is the name of the location below the earth’s surface where the earthquake starts?
It is called the hypo-center.
What causes an earthquake.
An earthquake is caused by compressional, tensional and sheer stress.
What was the highest level of earthquakes on the Richter Scale.
The highest level was in excess of 7.5.
What are the 3 different types of movement in the tectonic plates.
The three types are transform,convergent and divergent.
What are tectonic plates?
Tectonic plates are rigid plates that move relative to one another.
What is a fore-shock?
A fore-shock is a smaller earthquake that happens in the same place as the larger earthquake.
Which part of the earth's geosphere do earthquakes typically occur.

What are the 4 main layers of the earth.
The layers are the inner core, the outer core, the mantle and the crust.
What are aftershocks?

What happens to a fault when an earthquake occurs.

What is the difference between a Tsunami and a Tidal Wave.
A Tsunami is cause by an underwater earthquake while a Tidal Wave is caused by the forces of the moon, sun, and planets upon the tides
Why does the earth shake when there is an earthquake?
It shakes because, when the friction releases, all the stored up energy is released.
Where does an earthquake happen.
Earthquakes happen within the earth's crust.
How big were these earthquakes compared to the San Francisco earthquakes.
They were nearly ten times bigger.
If there are more earthquakes in this area, there are more _____ in this area
If there are more earthquakes in the area, there are more fault lines in this area.
