4. Biodiversity:
The equatorial rainforests in Africa are home to a wide range of plant and animal species. The Congo Basin, located in Central Africa, is the second-largest rainforest in the world and is known for its rich biodiversity. The continent's unique position on both sides of the equator contributes to the diverse ecosystems found in Africa.

In conclusion, Africa is the continent that lies on both sides of the equator. Its location, equatorial countries, climate, and biodiversity all contribute to its unique geographical features.
