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: -The area where the plates are pulling apart is known as a divergent boundary. The valley floor is called a graben and the valley sides are called horsts. Well-known rift valleys under the ocean are the Mid-Atlantic Ridge and the East Pacific Rise.

Detailed explanation-3: -The East African Rift Valley (EAR) is a developing divergent plate boundary in East Africa. Here the eastern portion of Africa, the Somalian plate, is pulling away from the rest of the continent, that comprises the Nubian plate.

Detailed explanation-4: -The Rift Valley, located in Eastern Africa, covers just over 2% of the continent and spreads over seven countries (Map 5 and Table 29). min. max. The Rift Valley consists of a group of independent interior basins, extending from Djibouti in the north to Tanzania in the south, nearly half being located in Ethiopia.

Detailed explanation-5: -The Great Rift Valley is the well known rift valley in the world. It stretches from the Middle East in the north to Mozambique in the south. It is well known for volcanoes, hot springs, geysers, and frequent earthquakes.
