Natural events such as volcanic eruptions and meteor impacts can cause earthquakes

earthquakes

Earthquakes strike suddenly, violently and without warning at any time of the year and at any time of the day or night.

fault lines:

key vocabulary:

abigailrf0519 — 2015-03-24 16:15:07 UTC

A fault is a thin zone of crushed rock separating blocks of the earth's crust

epicenter and focus picture:

key vocabulary:

The epicenter is the center point of the earthquake,

key vocabulary:

focus: The location where the earthquake begins

a transform boundry is a type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction

An S Wave, or seiesmic wave, is a seismic bodywave the happens as an aftershock of the earthquake.

key vocabulary:

abigailrf0519 — 2015-03-24 16:58:17 UTC

P Wave: alternatingly compressional and extensional, and cause the rocks they pass through to change in volume

key vocabulary

abigailrf0519 — 2015-03-31 17:02:37 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.

How earthquakes are formed

abigailrf0519 — 2015-04-07 15:55:32 UTC

Earthquakes are caused when rock underground breaks along a fault. This sudden release of energy causes the s 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 techtonichs

abigailrf0519 — 2015-04-07 16:04:51 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

Ideal place to live:

I would most likely live in a country that is in the middle of a plate tectonic so there wouldn't be earthquakes that would effect the way i live and the ares around me
