What is the terrain and geography like in Nigeria?
The country's major geographical features are the Niger and Benue Rivers. The two rivers form the upper arms of a flattened letter Y, coming together in the south-central part of the country, and proceed due south as the Niger River, fanning out into a large and intricate delta as the waters reach the Gulf of Guinea. Most of Nigeria's oil deposits are found in the Niger delta or in the coastal waters. The country's highest peaks are in the eastern highlands bordering Cameroon, with elevations up to 7,936 feet. The most extensive upland area is the Jos Plateau in east-central Nigeria, a region 2000 to 4000 feet above sea level with elevations up to 5841 feet.
A distinctive feature of Nigerian weather is the harmattan, a dry northeasterly wind that carries sand from the Sahara south as far as Nigeria's coast during the months of December through February. The effects of the harmattan are felt strongest in the northern part of the country and decrease gradually the further south one goes. Visually, the harmattan creates a haze that on certain days can almost block the views of the surrounding hills in the Abuja region. Many people experience eye, nose and throat problems during this time of year.
