Document Summary
Plate tectonic are important part because it is the reason for the earthquakes and volcanos. Earth"s internal energy: find the origin, the source, it is good for the aging how old is the rock and find out all the radio active materials. Started with rotation of the cloud (solar nebus) , ice, gas , dust. With compression of the disk, the speed of rotation increases. Began the formation of planets , combination of gravitational energy. With fusion, high temperature the small molecules combine with other molecules to create complex molecule. Density and strength r the two types in the layers. Center part of the earth soild, and outer is liquid part which is spinning in circular rotation. Mentle is the most important part of the plate tectonic , heavy rock effect the plates (density) makes the plate move. Soft plastic and stiff plastic are part of lithosphere. Metal is divided into lithosphere and asthonsphere.
