Physical geography
Sierra Leone is located on the west coast of Africa, between the 7th and 10th parallels north of the equator. Sierra Leone is bordered by Guinea to the north and northeast, Liberia to the south and southeast, and the Atlantic Ocean to the west. The country has a total area of, divided into a land area of and water of.Sierra Leone has four distinct geographical regions: coastal Guinean mangroves, the wooded hill country, an upland plateau, and the eastern mountains. Eastern Sierra Leone is an interior region of large plateaus interspersed with high mountains, where Mount Bintumani rises to.
Geology
Sierra Leone can be split into three geological areas, in the east is part of the West African craton, the western area consists of the Rokelides, an orogenic belt, and a 20- to 30-km coastal strip of sediments.Extreme points
This is a list of the extreme points of Sierra Leone, the points that are farther north, south, east or west than any other location.- Northernmost point – the northern section of the border with Guinea, Northern Province*
- Easternmost point – the tripoint with Guinea and Liberia, Eastern Province
- Southernmost point – unnamed peninsula south of the town of Mano Salija at the mouth of the Mano River, Southern Province
- Westernmost point – the point at which the border with Guinea enters the Atlantic Ocean, North West Province
- *''Note: Sierra Leone does not have a northernmost point, the border being formed here by 10th parallel north''
Climate
The climate is tropical; although it could be classified as a tropical monsoon climate, it could also be described as a climate that is transitional between a continually wet tropical rainforest climate and a tropical savanna climate.There are two seasons; dry season and rainy season.
December to January are the coolest months of the year, although temperatures can still exceed, lower to moderate humidity makes the heat around this time of the year more tolerable. Unlike March and April, the months that it gets hot and humid with temperatures around and a solid 50% humidity, making the heat index higher than the actual temperature. The average sea temperature is.
Average rainfall is highest at the coast, per year; moving inland this decreases and at the eastern border of the country, the average rainfall is.
Environment issues
Rapid population growth in Sierra Leone has put pressure upon the natural environment. Environmental problems include the overharvesting of timber, the expansion of cattle grazing and slash and burn agriculture have resulted in deforestation and soil exhaustion, and overfishing.Sierra Leone is party to several environmental agreements:
- Biodiversity
- Climate Change
- Desertification
- Endangered Species
- Law of the Sea
- Marine Life Conservation
- Nuclear Test Ban
- Ramsar Convention
