Answer :

Final answer:

Rift valleys are created at divergent plate boundaries through the process of crustal thinning and splitting due to magma upwelling, leading to the formation of unique landscape features called rift valleys.


Explanation:

Rift valleys are formed by divergent plate boundaries, where plates move away from each other. This process involves the rising of magma beneath the continent, thinning and splitting the crust, ultimately resulting in the formation of a rift valley. Examples include the East African Rift and the Great Rift Valley in Africa.
