What exactly causes wind?
In: Physics
differences in air pressure. hot air has more energy, so it pushes against colder air, and wants to go to where the cold air is (the area of less energy). these masses of air pushing against each other and changing places is what we feel as wind.
Wind on our planet starts at our star, so ultimately wind is caused by a large nuclear fusion reaction.
Ultimately, it’s caused by the sun.
When air gets hot, it expands, the density gets lower. When air cools, it contracts, the density gets higher. The sun doesn’t heat all the air on the planet evenly, resulting in some areas having high density and others low density.
The air all wants to be an even density, so air molecules will flow from high-density regions to low-density regions to even it all out. That flow of air molecules is the wind.
The bigger the difference between the high density and low density areas, the more rapidly the air moves, the stronger the wind.
It’s like when you boil water and it makes the water move around. Except the stove is the sun, the pot is our atmosphere, and the air is the water.
Convection. Warm air rises and cool air falls. The horizontal motion of these Hadley Cells is called “wind”
Food contains tiny air pockets trapped inside as you eat it. Inside the colon, the fart will form and that causes you to pass winds.
