how do earquakes originate. they are caused by tectonic plates shifting beneath the surface of the earth. the movement causes part of the surface to shake which we call earthquakes.
The prism is a three dimensional object. 3-D objects do not just have area. They have something call surface area, which is the amount of around on the surface of the object. 3-D objects also have volume. Volume is the amount of space inside the object. You can not work out the surface area of volume of just a prism. There are many many prisms out there. Prisms have many shapes and sizes.
An ellipse is a two dimensional shape, so it does not have a "surface area", only an "area". Any ellipse has two radii, the major one and the minor one. We'll call them R1 and R2. The area of the ellipse then can be calculated with the function: a = πR1R2 You will notice that this is the same equation as the area for a circle. The circle is a special case though, because it is an ellipse in which both axes are the same length. In that case, R1 equals R2, so we can simply call it r and say: a = πr2

The Oceans make up about 70% of the surface area of this planet. Seems kinda odd, then - why do we call it "Earth", and not "Water" ?
Scientists call a rock that strikes the Earth's surface a meteorite.

It is magma
Molten rocks under the Earth's surface are called magma. When magma reaches the Earth's surface, it is then called lava.

The area directly above the focus of an earthquake is called the epicenter. This is the point on the Earth's surface directly above where the earthquake originates in the crust.
