why does warm air rise and cold air sink
Answer (1)
Answer:Warm air rises and cold air sinks because of differences in density and buoyancy.1. Density Difference – Warm air is less dense than cold air. When air is heated, its molecules move faster and spread apart, making it lighter. Cold air has molecules that move slower and stay closer together, making it denser.2. Buoyancy – Because warm air is less dense, it is pushed upward by the denser, heavier cold air. This process is similar to how oil floats on water because it is less dense.3. Convection – This rising and sinking motion creates convection currents, which drive weather patterns and airflow in the atmosphere.This principle is why hot air balloons rise, warm air moves up in a room, and weather systems form.
