The countries of Africa (Egypt and the South African Republic)

Egypt

Two-third of the area of Egypt is covered by desert. The arable lands lie on the two coasts of the River Nile where 55 million inhabitants live. The Capital is Cairo, the „city of mosques”. (There are 500 mosques and minarets in Cairo.) The official language is arabian, the most widespread religion is the Muslim.

Global Warming

From the 20th century the warming of the air is continously strenghtening.The deforestation and the desertification also help the warming of the air because CO2 in 50% is responsible for global warming.

The role of the ozone layer is decisive because if the ozone layer hurts the ultraviolet radiation can reach the earth’s surface which destruct human beings.

The atmosphere

Composition:

The atmosphere is a mixture of different gases, but it also contains particles in liquid and solid states.

The energy policy of the world

The operation of the economy and the life of the society would be unimaginable without power generation.

The Global Air Circulation

On the sphere-shaped ^{gömb alakú} Earth warming up differs at the different places. It is the strongest along the Equator, and the weakest at the poles, and due to this the air pressure is low at the Equator and high at the poles. Low pressure zones form in the district of the latitude 60 and high pressure zones around the latitude 30. Due to the cyclones and anticyclones forming in the jet streams, the moving of the air is ascending (low-pressured zones) and descending (high-p.z.).

Europe

Europe lies mainly ont he northern and eastern hemisphere, but a little part of it lies ont he western one as well. Europe ont he east tightly belongs to Asia that is why it is sometimes called the peninsula of Asia. Their common name is Eurasia.
