What Are The 4 Types Of Plate Tectonics?

What are the types of plate tectonics?

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries.

This image shows the three main types of plate boundaries: divergent, convergent, and transform..

What are the 5 types of plate boundaries?

Plate Boundaries and Hotspot DemonstrationDivergent Plate Boundary. Volcanic eruptions and shallow earthquakes are common where plates rip apart.Convergent Plate Boundary. … Transform Plate Boundary. … Hotspot.

What are the 3 theories of plate tectonics?

Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth’s geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes.

What happens when two plates collide?

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. … The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.

How old is the African plate?

What are the 4 types of tectonic plate movement?

There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones.

Do all tectonic plates move?

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.

What are the 12 major plates?

Primary platesAfrican plate.Antarctic plate.Indo-Australian plate.North American plate.Pacific plate.South American plate.Eurasian plate.

What are the 7 plates on Earth?

There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.

What is the most studied transform fault in the world?

San Andreas FaultThe San Andreas Fault is one of the most intensely studied faults on the planet. It is a continental transform that separates the Pacific plate from the North American plate along its entire trace.

What are the 13 major plates of the world?

There may be scientific consensus as to whether such plates should be considered distinct portions of the crust; thus, new research could change this list.African Plate. … Antarctic Plate. … Australian Plate. … Caribbean Plate. … Cocos Plate. … Eurasian Plate. … Nazca Plate. … North American Plate.More items…

What causes the plates to move?

The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other.

What are the three types of plate tectonics?

Tectonic Plates and Plate BoundariesThere are three main types of plate boundaries:Convergent boundaries: where two plates are colliding.Divergent boundaries – where two plates are moving apart.Transform boundaries – where plates slide passed each other.

What are the smallest plates?

By far, the smallest plate in this list is the North Galapagos microplate.
