In Asia, home to more than half the world’s population. If you look at the figures, you can see that Asia has 3981 million people throughout 48 countries. The population settled unevenly due to the different climate. Despite its sometimes harsh weather conditions, Asia is the most densely populated part of the world.
This continent occupies 1/5 of the land. Africa is the second largest continent on the planet, there are 53 countries, home to 960 million people. Most of the space is state of the Sudan. Africa is considered to be the hottest continent. The snow here is only on the tops of the volcanoes. This continent is situated on 30 000 000 sq. km.
