Plate Tectonics
Ever since the beginning on time, Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth, and possibly of what the Earth may become at a certain point in time, has a great influence on understanding all aspects of living things, either in the past, present, or future. The study of Plate tectonics is accredited to most of the creations of Mountain Ranges, the drifting of continents, earthquakes, and volcanic activity. Plate tectonics and mountains also play a big part in the geological features of our planet or any planet for that matter.
Geophysics, which studies the physics of the Earth, has led to many important findings about the Earth and how it is made. Seismologic studies of planet Earth have revealed new information about the inside of the Earth that has helped to give new openings in understanding plate tectonics. The Earth is made of several significant layers. Each one of these layers has its own properties. The crust is the outermost layer of the Earth. The crust is made up of the oceans and continents. The crust has a fluctuating thickness, being thirty to seventy-five kilometres thick in the continents and ten to fifteen kilometres thick in the ocean basins. The crust is made up mainly of alumino-silicates (Fowler p472).
The layer underneath the crust is the mantle, which is made up mainly of ferro-magnesium silicates. The mantle is approximately two thousand, nine hundred kilometres thick, and is separated in to the upper and lower mantle. It is in the mantle where most of the centralized heat of the Earth is located. Big convective cells in the mantle disperse heat and produce the plate tectonic processes.
The core is the last layer of the Earth, which is broken down into the liquid outer core and the solid inner core. The inner core
