GEOLOGY

Detailed explanation-1: -A rift valley is a lowland region that forms where Earth’s tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

Detailed explanation-2: -Divergent plate boundaries, which are associated with the formation of rift valleys, occur when plates move away from one another. Convergent plate boundaries move toward one another, pushing into one another and are likely to create mountain ranges.

Detailed explanation-3: -Divergent Boundaries As the plates separate along the boundary, the block between the faults cracks and drops down into the soft, plastic interior (the asthenosphere). The sinking of the block forms a central valley called a rift. Magma (liquid rock) seeps upward to fill the cracks.

Detailed explanation-4: -Explanation: Two major landforms that are created from divergent boundaries are the rift valleys and mid-oceanic ridges.

Detailed explanation-5: -The earthquakes that occur along these zones, called spreading centers, are relatively small. The Great Rift Valley in Africa, the Red Sea and the Gulf of Aden all formed as a result of divergent plate motion. Convergent (Colliding): This occurs when plates move towards each other and collide.
