Plate Tectonics

madisonw0516 — 2015-03-19 18:15:49 UTC

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere.

Whats a richter scale

madisonw0516 — 2015-03-19 18:17:54 UTC

The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.

Divergent Boundries

madisonw0516 — 2015-03-23 18:10:42 UTC

Is a linear function that occurs when two boundaries are moving away from each other.

Convergant Boundries

madisonw0516 — 2015-03-23 18:22:19 UTC

Are Boundries that move towards each other and one ends up going under each other

Mantle

madisonw0516 — 2015-03-23 18:28:24 UTC

One of three main layers of the eartih, it lies between the inner most layer and the crust. It consists of dense, semisolid rock

How Do They Form

madisonw0516 — 2015-03-24 18:04:00 UTC

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little.

Theory of plate tectonics

madisonw0516 — 2015-03-24 18:07:16 UTC

Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface relative to each other, like slabs of ice on a lake

Transform Boundries

moving horizontally,moving in opposite directions: grinding against each other.

Outer Core

madisonw0516 — 2015-03-24 18:22:56 UTC

The Earth's outer core is a liquid layer about 2,300 km (1,400 mi) thick composed of iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.

Inner Core

madisonw0516 — 2015-03-31 17:47:00 UTC

The Earth's inner core is the Earth's innermost part and according to seismological studies, it is a primarily solid ball with a radius of about 1220 kilometers, or 760 miles (about 70% of the Moon's radius).

Crust

madisonw0516 — 2015-03-31 17:48:37 UTC

In geology, a crust is the outermost layer of a planet. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.

P wave

madisonw0516 — 2015-03-31 17:50:24 UTC

P-waves are a type of body wave that is the first wave to arrive at the seismograph, called seismic waves in seismology, that can travel through a continuum. The continuum is made up of gases (as soundwaves), liquids, or solids, including the Earth. P-waves can be produced by earthquakes and recorded by seismographs

madisonw0516 — 2015-03-31 17:51:17 UTC

S wave

madisonw0516 — 2015-03-31 17:52:57 UTC

a transverse earthquake wave that travels through the interior of the earth and is usually the second conspicuous wave to reach a seismograph.

France

madisonw0516 — 2015-03-31 18:25:24 UTC

I would like to live in France and it has had earthquakes, the last one was 8 years ago. France is not on a fault line or boundry!

Average Magnitude of Earthquakes in SC?

madisonw0516 — 2015-04-07 17:56:26 UTC

3.1 is the average

What causes earthquakes the most?
