What happens when divergent boundaries procedure inside

What are plateTetons? Plate tectonics is a concept in which the Earth’s surface is dividedinto numerous plates that glide over the mantle. A mantle is a gravel innerlayer above the earth’s core.

Plate tectonics helps to explain how earthquakes,volcanoes, mountains, and continents are formed. There are three kinds of plateboundaries, divergent, convergent, and transform. A divergent boundaryis when plates getting pulled apart from each other. Example, Red Sea basin.There are spreading centers along this plate. Spreading center is an area wherenew crust is formed, where two crustal plates are moving.

Example, mid-oceanicridge. Continental rifting happens when divergent boundaries procedure inside continentallandmasses. When this happens usually large lakes, rivers, and beaches are theresult. Crustal extension also occurs in a divergent plate.

Crustal extensionis where divergent plate forms under a continual landmass. A convergentboundary is when plates are being pushed together. Example, Andes Mountains.Transform boundary is two plates passing by each other.

Example, San AndreasFault. There are threedifferent types of convergent plate boundaries, OC/CC, OC/OC, CC/CC. Subductionof ocean crust beneath continental crust (OC/CC), this area is denser and hasthinner ocean crust which is subducted under less dense continental crust.

Deepand shallow tsunami are usually produced as well as explosive volcanoes in thisarea. Example, Andes in South America. Subduction of ocean crust beneath oceancrust (OC/OC), this area is denser, cooler, and older. Cooler ocean crust issubducted under less dense, younger, and warm ocean crusts. Deep and shallow tsunamiand volcanoes are not as explosive as OC/CC. Example, Aleutian Islands(Alaska). Continental Collisions (CS/CS), neither of continental crusts aresubducted.

This area is where large mountains are formed. Example, Himalayas. There arehotspots in the earth’s upper mantle that has very hot magma.

Hotspots underneaththe earth’s lithosphere which are caused by plumes rising. Example, Hawaii and YellowstoneNational Park. Some hotspots can remain in the same place for 10 million years.They can also happen underneath any type of crustal.

How are platesmoved? According to researchers, the convective flow in the earth’s mantle isthe basic force which moves the plate tectonics. There are three forces whichdrive the plate motion. Slab-pull, this is the slow pull of mantle from a highlocation to a low sinking location. Slab-suction, high density of cold oceancrust that is sinking into mantle, which pulls crust along with it.

Ridge-push,warm new ocean crust rises above the ocean floor while pushing cooler oldercrust away. Because of the plate tectonics theory, we are able to under andexplain earth’s big processes. Continental Accretion is when material is addedto plate tectonic plate. Baja California, part of the southern San Andreas Faultis being torn away from North America continent. California is the most studiedregion due its subduction zone activity and earthquakes. Californiatransitioned from an inactive margin to an active boundary with the transitionto subduction zone.
