1. The plate tectonic theory explains the presence of the East African Rift System, a series of rift valleys that run through East Africa. This is caused by the divergence of the African Plate and the Somali Plate, leading to the stretching and thinning of the Earth's crust in this region.
2. The theory also explains the presence of the East African Plateau, a highland region that covers much of East Africa. This plateau is believed to have formed as a result of the uplift of the crust due to tectonic forces.
3. The theory helps to explain the presence of volcanic activity in East Africa, particularly in the East African Rift System. This is due to the movement of magma from the mantle to the Earth's surface along the rift valleys.
4. The theory also explains the presence of the Great Rift Valley, a large trench that runs through East Africa. This is believed to have formed as a result of the movement of tectonic plates and the stretching of the Earth's crust.
5. The theory helps to explain the presence of the African Plate moving northward and colliding with the Eurasian Plate, leading to the formation of the Ethiopian Highlands in East Africa.
6. The theory also explains the presence of the East African Plateau being uplifted and eroded over millions of years, leading to the formation of various landforms such as mountains, valleys, and plains.
7. The theory helps to explain the presence of the East African Lakes, such as Lake Victoria, Lake Tanganyika, and Lake Malawi. These lakes are believed to have formed as a result of tectonic forces creating depressions in the Earth's crust that were later filled with water.
8. The theory also explains the presence of the East African Mountains, such as Mount Kilimanjaro and the Rwenzori Mountains. These mountains are believed to have formed as a result of tectonic forces causing the uplift of the Earth's crust.
9. The theory helps to explain the presence of fault lines and earthquakes in East Africa, particularly along the East African Rift System. These are caused by the movement of tectonic plates and the release of built-up stress in the Earth's crust.
10. Overall, the plate tectonic theory provides a comprehensive explanation for the present landforms in East Africa, highlighting the role of tectonic forces in shaping the region's geology and topography.

10 Ways Plate Tectonics Explains Present Landforms in East Africa:
1. Rift Valley Formation: The Great Rift Valley is a consequence of the divergence of the African Plate, creating deep trenches and uplifted shoulders.
2. Mount Kilimanjaro: A stratovolcano formed at the intersection of three tectonic plates, resulting in volcanic activity and the creation of its prominent peak.
3. Mount Kenya: Another stratovolcano formed by the subduction of the Indian Ocean Plate beneath the African Plate, leading to magma rise and eruption.
4. Lake Victoria: A remnant of the ancient Lake Mega-Chad, which formed in a depression created by extensional forces during the separation of the African Plate.
5. Serengeti Plains: A vast savanna formed on the stable Tanzanian Craton, which has been uplifted and eroded over time.
6. Ethiopian Highlands: Formed by the collision of the African and Arabian Plates, resulting in the uplift of the Ethiopian Plateau.
7. Red Sea: A consequence of the divergence of the African and Arabian Plates, creating a narrow body of water between the two landmasses.
8. Socotra Archipelago: A group of islands formed by the collision of the African and Eurasian Plates, creating a unique geological setting.
9. Madagascar: A large island that separated from Africa 165 million years ago due to continental drift and the formation of the Indian Ocean.
10. Okavango Delta: A wetland created by the flooding of the Okavango River, which flows into a depression created by extensional forces during the separation of the African Plate.
