Question

how are Continental plates destroyed

Answer 1

As we know the continental plates are constantly being pushed and therefore keeps moving slowly. As a result of this movement one plate pushes another neighbouring plate. A lot of pressure is exerted by each of them on the other. One plate is pushed under into the mantle while the other plate is pushed up to form a chain of mountains. In the margin of plates where one plate meets another often the incoming plate and goes into the mantle and becomes molten due to the heat of the mantle. Thus the plates eventually get destroyed.

$\huge{\bold{\underline{Answer:}}}$

• According to geologists continents and oceans are actually situated on massive base of rocks called plates, that are floating on the mantle.

• Continental plates are formed due to the activities like sea floor spreading in which the lava raising up from the mantle are hardened into rock creating new rocks.

• These plates are constantly pushed and therefore keep moving slowly.

• This movement of plates is called plate tectonics.

• While this movement continues, they pushes/collide each other, a lot of pressure is excreted by each of them on the other.

• The plate thus going under into the mantle becomes molten.

• It actually pulls the rest of the plate in to the mantle. Thus the plate is destroyed.
