Final answer:
The tropics receive more rainfall than other places on earth due to several factors, including warm air holding more moisture, proximity to the equator causing frequent rainstorms, and the influence of the ocean and mountain ranges.
Step-by-step explanation:
The tropics receive more rainfall than other places on earth due to several factors. One of the main reasons is that warm air can hold more moisture than cold air, so tropical areas receive more rainfall. Additionally, the tropics are closer to the equator, where the intense sunlight heats the air and causes it to rise and cool, leading to frequent rainstorms. The proximity to the ocean and mountain ranges also plays a role in the amount of precipitation received in tropical areas.
