Answers & Comments
Answer:
1. Plate tectonics is a scientific theory describing the large-scale motion of the plates making up Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago.
2. These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
3. Most movement occurs along narrow zones between plates, plate boundaries, where the results of plate-tectonic forces are most evident. Atlantic ocean, along a global system of mountain ridges, Earth's plates are growing and spreading apart.
4. Convergent, divergent and transform-fault boundaries.
5. ENDOGENIC PROCESSESS are the processes of internal origin. It takes place inside the globe and are started by the forces of the Earth. ... Exogenic processes are forces on or ABOVE Earth's surface while Endogenic processes are tectonic movements BELOW the surface of the Earth.
