Question

distinguish between convergent and divergent plate boundary ? give three point

Answer 1

Hello friend,

Divergent boundary:-
1. Divergent boundaries are boundaries where plates pull away from each other.
2. They form mild earthquakes and volcanoes as magma comes to the surface.


Convergent boundary:-
1. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands.
2. They are the sinking oceanic plate.

Hope it helps

Answer 2

Now, as plates pull apart, several things may occur. First of all, volcanic activity is common in these areas since mantle easily moves to the surface through the thin, fractured rock as it separates. Volcanoes are a sign of a divergent boundary. This happens all along the mid-ocean ridge where magma is constantly streaming to the surface, creating new ocean floor as the plates separate.

If a continent happens to be a place where a divergent boundary occurs, then the continent will begin to be torn apart as the sides of the plates separate, creating a rift valley. The African Rift Valley in East Africa is an example of this occurrence. Eventually, the ocean will separate East Africa from the rest, Divergent BoundaryConvergent Boundary

A second way cars interact (unfortunately) is by colliding. When cars impact each other or another solid object, the energy is transferred to the cars themselves, showing up as dents, ripples, or cracks. Plates also show tell-tale signs of colliding, too, depending on the kind of crust colliding.

Remember that at divergent boundaries, new crust is being made, but the earth is not getting larger. Why not? Well, at the opposite ends, crust is being pushed into the earth's interior by colliding plates and being re-melted at the same rate new crust is formed. This happens at a convergent boundary. A convergent boundary is a boundary where two separate plates are pushing into each other.

There are two kinds of surface features that are associated with a convergent boundary. The first is a deep ocean trench that forms a line of the two colliding plates. One plate made of oceanic crust can slide down underneath another plate, forming this narrow, deep trench. This happens because oceanic crust is more dense than continental crust, making it more likely to be pushed back into the mantle. These trenches are the deepest places on the face of the earth, extending over 30,000 feet below the ocean surface. You could take Mount Everest and sink it in the Mariana Trench, the deepest point in the ocean, and still have a mile to the surface of the ocean. That's deep!

As one plate is forced under the other one, it begins to melt, and a line of volcanoes forms in a parallel line to the trench. If the other plate is oceanic crust, the line of volcanoes will become islands, like the Philippines, and if it is continental crust, then it will become a line of volcanic mountains, like the Cascade Range in the western U.S. or the Andes Mountains in South America.

The first way two cars can move relative to each other is in divergent directions, like passing a car going the other way. Plates also can pull apart from each other. This is known as a divergent boundary.
