Earthquakes
The earth we live on consists of the ocean, and the continents. Below the ocean and continents we have the earth’s crust, which can very in length for miles. Under the earth’s crust we encounter small breaks in the earth, which is caused by the slow movement of mantle. With this movement we find the plates of the continent breaking apart and causing earthquakes (Nicholls, Bill 2). The earth’s mantle roughly extends about 1,798 miles. The density of the mantle changes because of pressure and heat. The further down the mantle is the more pressure and heat we encounter (Nicholls, Bill 1). The world’s lithosphere covers the entire earth (outer shell) and can be broken in many places to form what is called plates. These continental and oceanic plates are constantly moving and they never stop. With the concurrent movement of our lithosphere many mountains, volcanoes, and earthquakes will be created because of these plates (Spall, Henry 1).
