While a mountain’s windward side gets soaked, the other side can dry out. Air rises, drops rain, then descends, warms, and loses moisture—creating a rain shadow.
A riverbed isn’t as fixed as it looks. When rains swell flow, sand and gravel move; bends shift, and a river can abandon an old path and carve a new one.
Sun warms the surface by day; at night the surface loses heat by radiating it into space. Clouds, humidity, and wind change this ‘heat escape,’ making some nights biting and others mild.
