What do the boundaries of the earth (tropics) receive most of and greatest of?

The boundaries of the Earth known as the tropics, specifically the Tropic of Cancer and the Tropic of Capricorn, receive the most direct sunlight throughout the year, leading to consistently high temperatures. This region experiences the greatest amount of solar energy and typically has high levels of precipitation, particularly in tropical rainforests. Consequently, the tropics support lush biodiversity and rich ecosystems due to these favorable climatic conditions.
