The surface of the earth was not flat like the previous allegations, but there was a lower high. Appearance on the surface of the Earth is often called the relief, the high and low state of the earth's surface. Relief is not only found on the mainland, but also present in the ocean.
Earth is divided into several layers, including:
a. Core (barisfer) consisting of nickel and Ferrum (NiFe) solid
b. Asthenosphere or mediator layer, a layer of liquid and incandescent
c. The lithosphere is the outer layer of the earth. This layer consists of a layer of aluminum silisium (unlucky) and silisium magnesium (sima).
Based on the theory of plate tectonics states that the Earth consists of several major plates and extra plates. The plate is divided into two major continental plates and oceanic plates, cover plates Asia, straightforward African American plate, Pacific Plate, Australian Plate, and Antarctic plates. The plates are not stationary but moving at a speed varying between 3-6 cm per year with different motions. In between there is the movement of these plates are colliding (convergent), nothing apart (divergent), and there's a rub against each other.
The two plates are colliding with the Asian plate as the Australian plate is formed mountain trails, trenches and seismic lines. The plates are rubbing together will form section. While the plates are far from each other will be formed ridge (ridge) or cracks.
As a result of the movement of the plates that form the earth there as there is today. These movements were the result of an enormous power contained in the earth.
