. The coldest regions in the world are the polar regions near the North and South Poles. They have an arctic climate. The hottest regions are in South Asia, North Africa and Central America, They are in the Tropics. Their climate is tropical.
The countries between the polar and tropical regions have a temperate climate. This is the climate of Europe. The average temperature there is warmer than at the Poles and cooler than that of the tropics.
The plant growth in a particular region is called its vegetation. The vegetation of an area depends on its climate. In wet, tropical regions, jungles (丛林) are the commonest vegetation. In theses jungles the tops of the trees are large, and meet overhead. Underneath there are smaller trees. The forests in the temperate regions are different. They do not have the thick undergrowth that is found in the tropical jungles. These forests, therefore, are more open than the jungles.
The deserts are the driest areas. They have very little vegetation at all. The regions farthest north and south of the Equator (赤道) experience ice, snow and frost all year round. Here, too, there is little or no vegetation.
