Namibia has more than 300 days of sunshine per year. It is situated at the southern edge of the tropics; the Tropic of Capricorn cuts the country about in half. The winter (June–August) is generally dry, both rainy seasons occur in summer, the small rainy season between September and November, the big one between February and April.
The Namibian education system has been evolving since the nation achieved independence, although the dream of equal education for all remains tantalizingly unreached. A program of pre-primary education is unrolling, and is hoped to be completed by 2013. Pupils spend their first 7 years at primary school from age 6, where they are promoted from grade to grade on the basis of competencies.
A river is a large body of water that flows over land in a long channel. Most rivers begin high in the mountains or hills. A river's source may be a melting snowfield or glacier (although in Namibia we generally rule these 2 options out!), a spring, or an overflowing lake. As a river flows in its channel, it receives more water from streams and other rivers, and from rainfall. At the end of a river is its mouth, where the water empties into a larger river, a lake, or an ocean.
