Final answer:
The African Transition Zone divides Africa into two distinct regions; North Africa and Sub-Saharan Africa, with different climates and cultures, and the Great Rift Valley is a significant physical feature in East Africa.
Step-by-step explanation:
The physical feature that divides Africa into two distinct regions is the African Transition Zone. This zone separates North Africa from Sub-Saharan Africa, characterized by differences in climate and cultural dynamics. While the northern part experiences a dry, arid climate predominantly present in the Sahara Desert, the southern region features tropical climates.
The Great Rift Valley is a significant and prominent physical feature of East Africa. It extends from North to South and is evidence of a tectonic plate split, creating the Somalian and Nubian Plates.
Due to global climate changes and its geography, Africa hosts a variety of terrains that have historically influenced the movement and interactions of people, cultures, and technologies across the continent.
