Divergent boundary
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary. This supplies the area with vast amounts of heat and a reduction in pressure that melts rock from the asthenosphere (or upper mantle) beneath the rift area forming large flood basalt or lava flows. Each eruption occurs in only a part of the plate boundary at any one time, but when it does occur, it fills in the opening gap as the two opposing plates move away from each other.

Two types of Divergent Plate Boundaries
Divergent plate boundaries occur when two tectonic plates move away from one another. Divergent plate boundaries are considered constructive boundaries. If you look at a map of the major tectonic plates you can see several divergent plate boundaries. There are two major types of divergent boundaries. Continental and continental lithosphere and oceanic and oceanic lithosphere. An example of an oceanic and oceanic divergent boundary is the mid-ocean ridge. The mid-ocean ridge runs around the world including going right through Ice land. A famous example of a continental and continental divergent boundary is the African rift valley.

Explanation of divergent plate boundaries and shield volcano's
Now that you know what plate tectonics is and what the structure of the earth is, we can look at the movement of the plates. Divergent zones are explained in this video. These are zones where the plates move apart. As you have seen in the previous video, the continental crust is much thicker than the oceanic crust. Under a continental crust, the mantle can therefore become very hot, because the mantle cannot lose the heat. The rock expands due to the heat. If the heat makes the rock fluid, it can expand even more. The expanding magma causes the continent to rise. The continent can therefore break, due to the pressure. Gravity then ensures that the broken plate will slip. This force is called ridge push. This is one of the reasons that plates move. A very long crack appears in the crust ...

Now that you know what plate tectonics is and what the structure of the earth is, we can look at the movement of the plates. Divergent zones are explained in this video. These are zones where the plates move apart.
As you have seen in the previous video, the continental crust is much thicker than the oceanic crust. Under a continental crust, the mantle can therefore become very hot, because the mantle cannot lose the heat. The rock expands due to the heat. If the heat makes the rock fluid, it can expand even more.
The expanding magma causes the continent to rise. The continent can therefore break, due to the pressure. Gravity then ensures that the broken plate will slip. This force is called ridge push. This is one of the reasons that plates move.
A very long crack appears in the crust where the plates move apart. Here material can rise from the mantle and solidify on the surface as basalt. This new crust is deeper than the previous continental crust. As a result, water flows to this low point. If the plates keep moving apart and more oceanic crust is created, an ocean can form.
The crack where oceanic crust is made sometimes lies exactly between 2 continental plates, and therefore in the middle of the ocean. Here the ocean is usually about 2500 meters deep, which is relatively shallow for the ocean. As a result, places where the plates move apart are also called Mid-Ocean ridges.
Close to the Mid-Oceanic Rug, the oceanic crust is relatively young and also warm. Over time, the crust moves away from the Mid-Oceanic Rug. The crust grows older, becomes cooler, which increases the density. This causes the crust to lie deeper, making the ocean 5.5 kilometers deep.
The part of the oceanic crust that is further away from the Mid-Ocean Ridge is already older, which means that more sediment layers have been deposited there, while with the younger crust, closer to the Mid-Ocean Ridge, fewer sediment layers could be deposited. This is proof that the crust at the Mid-Oceanic Rug is younger and therefore originated there.
Because the plate is stretched at starting divergent zones, it becomes thinner. You can compare this process to stretching an elastic band. Stretching will lower the crust. The low-lying part in the middle of the divergent zone is called a graben. The sides remain relatively high. We call these high-lying parts a horst. This causes some relief in the region.
With a divergent movement, basaltic magma emerges. Because basaltic magma is very liquid, shield volcanoes arise in divergent zones. These are volcanoes that are very wide, but not very high. That is because the liquid basaltic magma flows away very easily, making the volcano very wide but not high. The volcano eruption is effusive. These are eruptions that go relatively smoothly.
So you have learned how a divergent movement arises, what consequences this has for the depth of the ocean and what type of volcanoes and volcanism can arise there.
In the next video, Convergent movements are explained.

Divergent plate boundaries occur when two tectonic plates move away from one another.
Divergent plate boundaries are considered constructive boundaries.
If you look at a map of the major tectonic plates you can see several divergent plate boundaries.
There are two major types of divergent boundaries.
Continental and continental lithosphere and oceanic and oceanic lithosphere.
An example of an oceanic and oceanic divergent boundary is the mid-ocean ridge.
The mid-ocean ridge runs around the world including going right through Ice land.

Now that you know what plate tectonics is and what the structure of the earth is, we can look at the movement of the plates. Divergent zones are explained in this video. These are zones where the plates move apart.
As you have seen in the previous video, the continental crust is much thicker than the oceanic crust. Under a continental crust, the mantle can therefore become very hot, because the mantle cannot lose the heat. The rock expands due to the heat. If the heat makes the rock fluid, it can expand even more.
The expanding magma causes the continent to rise. The continent can therefore break, due to the pressure. Gravity then ensures that the broken plate will slip. This force is called ridge push. This is one of the reasons that plates move.
A very long crack appears in the crust where the plates move apart. Here material can rise from the mantle and solidify on the surface as basalt. This new crust is deeper than the previous continental crust. As a result, water flows to this low point. If the plates keep moving apart and more oceanic crust is created, an ocean can form.
The crack where oceanic crust is made sometimes lies exactly between 2 continental plates, and therefore in the middle of the ocean. Here the ocean is usually about 2500 meters deep, which is relatively shallow for the ocean. As a result, places where the plates move apart are also called Mid-Ocean ridges.
Close to the Mid-Oceanic Rug, the oceanic crust is relatively young and also warm. Over time, the crust moves away from the Mid-Oceanic Rug. The crust grows older, becomes cooler, which increases the density. This causes the crust to lie deeper, making the ocean 5.5 kilometers deep.
The part of the oceanic crust that is further away from the Mid-Ocean Ridge is already older, which means that more sediment layers have been deposited there, while with the younger crust, closer to the Mid-Ocean Ridge, fewer sediment layers could be deposited. This is proof that the crust at the Mid-Oceanic Rug is younger and therefore originated there.
Because the plate is stretched at starting divergent zones, it becomes thinner. You can compare this process to stretching an elastic band. Stretching will lower the crust. The low-lying part in the middle of the divergent zone is called a graben. The sides remain relatively high. We call these high-lying parts a horst. This causes some relief in the region.
With a divergent movement, basaltic magma emerges. Because basaltic magma is very liquid, shield volcanoes arise in divergent zones. These are volcanoes that are very wide, but not very high. That is because the liquid basaltic magma flows away very easily, making the volcano very wide but not high. The volcano eruption is effusive. These are eruptions that go relatively smoothly.
So you have learned how a divergent movement arises, what consequences this has for the depth of the ocean and what type of volcanoes and volcanism can arise there.
In the next video, Convergent movements are explained.

Cosmology & Astronomy on Khan Academy: The Earth is huge, but it is tiny compared to the Sun (which is super huge). But the Sun is tiny compared to the solar system which is tiny compared to the distance to the next star. Oh, did we mention that there are over 100 billion stars in our galaxy (which is about 100,000 light years in diameter) which is one of hundreds of billions of galaxies in just the observable universe (which might be infinite for all we know). Don't feel small. We find it liberating. Your everyday human stresses are nothing compared to this enormity that we are a part of. Enjoy the fact that we get to be part of this vastness!

This video describes the characteristics of divergent plate boundaries including the distribution of earthquakes, the elevation of the sea floor, and the age of the rocks along the oceanic ridge system. We spin some globes, fade some maps and label some sketches to show you what happens when a continent is split apart to form a new ocean basin. You will visit remote locations in east Africa and the Red Sea and figure out why the Pacific Ocean is wider than the Atlantic even though they are the same age and were formed by the same processes.

Divergent boundary
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.
Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary. This supplies the area with vast amounts of heat and a reduction in pressure that melts rock from the asthenosphere (or upper mantle) beneath the rift area forming large flood basalt or lava flows. Each eruption occurs in only a part of the plate boundary at any one time, but when it does occur, it fills in the opening gap as the two opposing plates move away from each other.
