Question

The rift valley formed when the crust pulled apart.
The rift valley formed due to subduction.
The rift valley formed similarly to an island arc.
The rift valley formed at a convergent boundary.

Answer 1

Answer:

The rift valley formed when the crust pulled apart.

Explanation:

The Great Rift Valley in Africa formed when the crust pulled apart along a divergent margin.

• Rift valley systems are produced within a continent at divergent margins within a plate.
• The rifting system makes the earth in that region prone to frequent earthquakes as the continents continues pulling apart.
• It results from the divergence of the Arabian plate and the Somalia/Nubian plate.
• It is one of the longest rift valley systems on earth.
