Plate Techtonics
Plate tectonics is the model we use to understand how our planet works. To go into detail it is a model that explains the origins of continents and oceans, folded rocks and mountain ranges, earthquakes and volcanoes, and continental drift. plate tectonics was first brought over 100 years ago but barely became a part of geology about 50 years ago.
Types of Boundaries:
There are three different types of boundaries; divergent, convergent and transform.
Divergent
The act of boundaries moving apart is divergent. where new oceanic crust is created from magma derived from partial melting of the mantle caused by decompression as hot mantle rock from depth is moved toward the surface
Convergent:
When two plates move towards each other it is known as a convergent boundary.
