The Tropics of Capricorn and Cancer are linked to several distinct physical features. The Tropic of Capricorn passes through dry regions like the Kalahari and Atacama Deserts due to high-pressure zones. Near the Tropic of Cancer, the towering Himalayas influence regional climate and rainfall. Both tropics also cross warm ocean areas that support rich marine life, such as the Great Barrier Reef near the Tropic of Capricorn.
