The landscape of Nigeria varies with mangrove forests and swamps bordering the southern coast, and hardwood forests further inland.
The Niger and Benue River valleys make up Nigeria's most expansive region, merging into each other to form a distinctive 'Y' shape.
The Mambilla Plateau, the highest in the country, forms the area southeast of the Benue, and is punctuated by hills and mountains, extending into the border with Cameroon.
Filling in the space between the far south and far north is a vast savannah made up of three zones: The Guinean forest-savanna mosaic, Sudan savannah and the Sahel savannah. Rain falls sparsely in the Sahel savannah, located in the northeast, and subsequently the Sahara Desert is encroaching.
Nigeria's highest point is Chappal Waddi at 7,936 ft (2,419 m); the lowest point of the country is the Atlantic Ocean (om).
The country shares Lake Chad in the northeast with Niger, Chad and Cameroon.
