Question

Explain the process of formation of Rift valley.

Answer 1

• When horizontal movements on the earth’s surface act in opposite direction, it causes tension on the rocks in the earth’s crust. 
• When tension increases, fractures develop in the rocks leading to the formation of faults. 
• Consequently, rocks on both the ends slide and the continuity in the layers of rocks is not found. 
• Sometimes, two fractures develop side-byside in the earth’s crust and land in between the two fractures subsides. This subsided deep part is called the rift valley.
