Africa is a
land of diversity and contrasts. This is true of its land,
climate, people, and wildlife. The continent of Africa
comprises one-fifth of the total Earth's land mass. It is
the second largest continent and is divided into 53
different countries. In 1994, the population of the
continent was estimated to be around 683,000,000 and is
comprised of several thousand different ethnic groups.
Africa's
coastline is 18,950 miles long, with very few inlets and
bays. From north to south the continent measures
approximately 5,000 miles in length. From east to west above
the Equator it measures approximately 4,600 miles.
Africa's land
mass was formed by a rigid platform of rock that serves as
the base for the widespread plateaus of the interior. From
the higher plateaus in southeastern Africa the land descends
into the plains and coastal lowlands of northeastern Africa.
The average elevation is 2,200 feet. Basically the plateau
can be divided into two regions. The southeastern portion
includes the Ethiopian Plateau, the East African Plateau and
the Drakensberg Range.
The
northeastern portion contains the Sahara Desert with the
Ahaggar Mountains, and in northwestern Africa, the Atlas
Mountains.
When viewing a
topographical map of Africa you will notice the East African
Rift System which runs from the north to the south of the
continent. It is made up of the Western Rift Valley and the
Eastern Rift Valley. It begins with the Red Sea basin,
follows along the Ethiopian Plateau with heights of 15,000
feet and includes the Virunga Mountains' volcanic
formations.
Mt. Kilimanjaro
is the most well known of the African mountains with an
elevation of 19,340 feet. Other mountains include the
Ruwenzori Range with elevations over 16,000 feet. in central
eastern Africa.
The Drakensberg
Range at 11,000 feet is on the southeastern coast. Up along
the northwestern coast are the Atlas Mountains at 13,000
feet however, the remainder of this region averages between
500 and 1,000 feet. It is also the region that contains the
Sahara Desert.
The world's
largest desert is The Sahara. It is a major land feature of
the continent since it is one-fourth of Africa's land mass.
It is located in the northwestern portion of the continent
and divides the continent into three regions - north of the
Sahara, the Sahara and Sub-Sahara. In southwestern Africa
there are two other notable deserts, the Kalahari and the
Namib. |
