A summary of the northern hilly

This division of Africa into almost two equal parts lengthwise across the equator makes the climatic and physical conditions in the north repeat themselves in the south. For example, the Kalahari Desert is the south's answer to the Sahara; the Karoo matches the Maghreb, while the conditions in the Cape area are almost identical to those of the Mediterranean region.

Africa is the most tropical of all continents. Climate and vegetation range from equatorial rainforests, tropical deserts and savanna grassland to Mediterranean.

The Sahara Desert, the largest of its kind anywhere in the world, is over Its surface is almost invariably consisting of a geologically stable land mass made up of the pre-Cambrian basement rock overlain in part by sedimentary cover of a later period. The continent is made up of very old crystalline, metamorphic, and sedimentary rocks of great hardness collectively known as 'basement complex'.

Africa's land mass is made up of a simple tectonic plate some geographers attempt to separate the Rift Valley system from the rest of the continent.

The continent has some extensive areas of faulted plateau. It has however suffered little in terms of folding hence young folded mountain similar to the Rockies and Andes are missing. Most of the highlands and mountains are the result of recent volcanic activities e.

Lower average altitudes characterize most of the areas in the North. The Southern and Eastern areas have most of the highest areas of the continent m. The African plateau is underlain primarily by Precambrian rock that dates back to more than years.

The Rift Valley System Fig 2. The Rift Valley begins from the Red Sea and extends through the Ethiopian highlands to the Lake Victorian region where it subdivides into an east and west segments and continues southward through Lake Malawi to Mozambique.

Its total length is estimated to be 6, miles 9, m. Average width ranges between 20 miles 32 km and 50 miles 80 km. The valley system has been occupied by elongated lakes lying within very deep trenches Lakes Tangayika, feet m below sea level, Malawi, Turkana, Albert, Nyansa.

Volcanic highlands and block moountains e. Ruwenzori massif 16, feet, m rises within the valley floor in places. The shape of Africa is relatively simple with a remarkably smooth outline. The rivers plunge off the edges of the plateau into the sea in a series of falls and rapids.

The coast is fringed with coral reefs, sand bars, mangrove swamps and lagoons that block passage to the continents interior. The coastline of Africa is remarkably straight, free from the indentations that make for good natural harbors. The narrow continental shelf is related to the steep face that the continent generally presents to the sea and the faulting that has produced its general shape.

The only place with an extended continental shelf is the Agulhas Bank extends kms or miles off shore. The absence of any major continental shelf as in Europe and the northeastern part of North America limits the development of fishing grounds and the opportunities of exploring for major petroleum sources of the coast.

No major coastal island except Madagascar - the 4th largest island in the world.

Cycling the North Sea Route

The coastline is generally smooth. The rivers are not effective as transportation routes due to the existence of a large amount of rapids and cataracts.

Almost all the rapids are found at points where the rivers descend the interior plateau some few kilometers from the coast.

For example, the Zaire River is interrupted by 32 rapids and cataracts which constitute the Livingstone Falls in a descent of approximately meters over a distance of kilometers. In other continents the rivers offer the best entry into the interior from the coast e. Lawrence and Mississippi and also served as a cheaper means of transportation for industrial goods but this is not the case in Africa.

Despite being impediments to transportation, most of the rivers provide a great potential for the production of hydro-electricity.EXPEDITION SUMMARY. This wolf volunteering expedition will take you to the beautiful lowlands of Lower Saxony, a federal state in northern Germany, to .
