Question

Explain the terms Divergent Margin, Convergent Margin and Transform Margin.

Answer 1

Instructions:

• Explain the meaning of each term
• Give examples to substantiate (1 x 3 = 3 Marks)

Solution:
The above three terms are with respect to the plate boundary movements. We know that the lithosphere is not a continuous layer and it floats on asthenosphere. This causes the movement of the lithospheric plates and it leads to plate interacting among themselves.

• Divergent Margin : When two plates move away from each other, the fault is created and the divergent margin is formed. E.g. Mid-Oceanic Ridge, African Rift Valley
• Convergent Margin: When two plates move towards each other, the fold is created and a convergent margin is formed. E.g. Himalayas
• Transform Margin: When two plates slide past each other, fault is created and tremors are felt. E.g. San Andreas Fault
