Tropical forests do more than store carbon; they also help to produce their own rain. Through a mech_____ called transp_______, trees abs___ water fr__ the so__ and rel____ it a_ vapor thr____ tiny po___ in lea___. This moisture rises, cools, and forms clouds that later fall as rain over the same region or over areas farther inland. When large tracts of forest are cleared, less vapor enters the air, and local rainfall can decline. Some scientists warn that extensive clearing could push parts of the Amazon toward a drier, savanna-like state.
