How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/physics/15-wind-and-weather/). - [0](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/0/) — Wind is simply air on the move, and air moves from places where it presses harder to places where it presses less, like a crowd spilling out of a full room into an empty one. - [1](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/1/) — On a sunny afternoon at the beach the sand warms faster than the sea, the warm air above it rises, and cooler air from the sea rushes in to take its place: that is the sea breeze on your face. - [2](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/2/) — Moving air pushes on whatever is in its way, so it can lift a kite, flip an umbrella, slam a door or, when it is very fast, push a tree over. - [3](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/3/) — The wings of a plane turn the air downwards, and the air pushes back up on the wings strongly enough to hold up a giant jet. - [4](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/4/) — Weather forecasters watch the air pressure: high pressure usually means calm, settled days, low pressure means clouds, wind and rain. - [5](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/5/) — Wind is air moving from where it presses harder to where it presses less. - [6](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/6/) — On a sunny day the land warms faster than the sea, so warm air rises over the land and cooler sea air blows in; at night the land also cools faster than the sea, so the breeze often turns round and blows out to sea. - [7](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/7/) — High pressure usually brings calm, settled weather, and low pressure usually brings clouds, wind and rain. - [8](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/8/) — A barometer measures air pressure, and a falling barometer warns that bad weather may be coming. - [9](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/9/) — The push of the wind grows very quickly with its speed: wind twice as fast pushes about four times as hard. - [10](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/10/) — A kite flies because the wind is turned downwards by the tilted kite and pushes it up, while the string holds it at an angle. - [11](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/11/) — A windsock shows which way the wind blows, and pilots take off into the wind because it gives the wings more air flowing over them. - [12](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/12/) — An umbrella turns inside out when a gust pushes up underneath it harder than from above. - [13](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/13/) — A plane's wings turn air downwards and make the air over the top flow faster with lower pressure, so the air pushes the wings up; the faster the plane goes, the more lift (upward push) its wings make, so it races along the runway first. - [14](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/14/) — A tornado is a column of air spinning very fast with very low pressure in its middle, and its winds can rip off roofs and lift cars. - [15](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/15/) — In a tornado people shelter in a cellar or a small room in the middle of the house, away from windows. - [16](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/16/) — Wind through an open window can push a door shut with a slam, which is why a door stop keeps fingers safe. - [17](https://md.mova.elamur.ai/free/en/corpora/school/physics/15-wind-and-weather/17/) — Blowing out a candle pushes the flame's hot gas away from the wick, while very gentle blowing can bring more air and make it brighter. - ← previous: [The air presses on everything](https://md.mova.elamur.ai/free/en/corpora/school/physics/14-the-air-presses-on-everything/) - next →: [Pressure tricks: pumps, tyres and vacuums](https://md.mova.elamur.ai/free/en/corpora/school/physics/16-pressure-tricks-pumps-tyres-vacuums/) - ↑ back to [Physics](https://md.mova.elamur.ai/free/en/corpora/school/physics/)
