For the formation of a rift valley, which of the following processes should occur in the earth’s crust?

Options

  • Compression

  • Tension

  • Weathering

MCQ

Solution

Tension

Explanation:

When the energy waves within the earth’s mantle move away from each other, they create tension on the layers of rock surrounding the waves leading to fractures in the earth’s crust. Sometimes, two fractures can occur parallel to each other and the crust between these fractures subside forming the rift valley.
