Which of the above statements is/are correct?
Q. Consider the statements regarding different types of plate boundaries:
Which of the above statements is/are correct?
The correct option is D Neither 1 nor 2
Explanation:
Statement 1 is incorrect: Divergent plate boundary or constructive plate boundary: A tectonic boundary where two plates are moving away from each other and a new crust is forming from magma that rises to the earth's surface between the two plates. The middle of the Red Sea and the mid-ocean ridge are divergent plate boundaries.
Statement 2 is incorrect: Convergent plate boundary or a destructive plate boundary: It is a tectonic boundary where two plates move towards each other. If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone. However, in the case of a divergent plate boundary, a consistent upwelling of molten magma takes place due to the incessant convection current in the mantle.
