Final answer:
The rainfall is centered in different areas depending on the region. Areas with high rainfall include Central and South America, Western Africa, and Southeast Asia where rainforests grow. Conversely, areas with little rainfall turn into deserts, such as North Africa, the Middle East, western North America, and Central Asia. In South Asia, tropical forests receive a significant amount of rainfall, and the monsoon rains bring moisture up to the Himalayas, feeding major rivers like the Brahmaputra, Ganges, and Indus.
Step-by-step explanation:
The rainfall is centered in different areas depending on the region. In Central and South America, Western Africa, and Southeast Asia, there are areas of high rainfall. These regions receive most of the world's rain and are where rainforests grow. On the other hand, areas with very little rainfall, such as North Africa, the Middle East, western North America, and Central Asia, turn into deserts. In South Asia, tropical forests receive nearly half of the world's rainfall, and the monsoon rains bring moisture to the region up to the Himalayas, feeding major rivers like the Brahmaputra, Ganges, and Indus.
