Question

In the divergent boundary, the plates __________.
A. Move toward each other
B.Sinks another another
C.Slide horizontally
D.Pull away from each other

Answer 1

Hint:Earthquakes are common in divergent boundaries and mantle is seen rising from the earth’s mantle to the surface which solidifies to create a new oceanic crust.

Complete answer: Divergent boundary is a linear feature in the theory of plate tectonics that takes place between two tectonic plates when they pull away from each other.This occurs due to the rise in convection currents.When a divergent boundary occurs in the continents,it creates a rift and later on creates a rift valley. The oceanic plates and mid-oceanic ridges are the most common places for a divergent boundary to occur. Divergent boundaries often give rise to volcanic islands. When a divergent boundary takes place beneath the lithosphere,the convection current underneath it rises,which lifts the lithosphere,creating a mid oceanic ridge. Tectonic Plate theory is a scientific explanation that the outer covering of the earth is divided into several plates which slide over the mantle, which is the rocky inner layer above the core. The outer layer is known as lithosphere which has a thickness of 100 km.

So, the correct answer is option D.

Note: The continental drift theory was first proposed by Alfred Wegener. This theory was developed from the 1950's through 1970’s. According to the world Atlas, there are nine major plates around the earth.These plates have been named after the landforms which were found on them.Therefore the names of the plates are: North American, Eurasian,African, Indo-Australian,Australian,Indian,South American and Antarctic.
