Equatorial forests are located on both sides of the equator in the Congo Basin and along the Gulf of Guinea north of the equator. Equatorial forests are located on both sides of the equator in the Congo Basin and along the Gulf of Guinea north of the equator. The formation of the zone is due to a large amount of heat and moisture throughout the year. The formation of the zone is due to a large amount of heat and moisture throughout the year.
