1. What is convection?
2. What resulted when cold air sinka?
3. What resulted when warm aur rises?
4. What resulted when the cool air flows to take the place of the rising warm air ?
- Convection is the transfer of thermal energy by particles moving through a fluid. … Moving particles transfer thermal energy through a fluid by forming convection currents. Convection currents move thermal energy through many fluids, including molten rock inside Earth, water in the oceans, and air in the atmosphere
- When air sinks, the air pressure at the surface of the Earth is raised. The sinking air will then compress and heat. The cold, dry air that sinks becomes warmer and dries out—leading to the rise of hot air once agai
- If warm moist air rises, it will expand and cool. As it cools, the relative humidity will increase and water will condense. It can then fall back to the earth as precipitation. … As air rises, it expands because there is less atmospheric pressure at higher altitudes.
- Since warm air is less dense and creates less air pressure, it will rise; cold air is denser and creates greater air pressure, and so it will sink
