Things we already know Wind is what state of matter? Convection currents occur in __________ or ____________
Other things we know -Cold air is more dense than warm air -As air is warmed it rises
Things are heated at different rates by the sun!
The basics of wind View the website wind/index.htm wind/index.htm Read for information : Pages in your textbook and fill in your notes sheet with your elbow buddy
Winds are caused by differences in air pressure Differences in air pressure are caused by unequal heating of the atmosphere Air over a heated surface becomes less dense and rises, cool dense air falls and causes wind
Wind directions is measured using a wind vane Wind speed is measured using an anemometer Wind-chill factor is caused because wind removes heat as it blows over your body
Local winds blow over short distances Caused by unequal heating within small areas, near mountains or water
Sea breeze- when the wind blows from an ocean or lake towards the land; happens in the day when the land warms faster than the water
Land breeze- happens at night when the land cools more quickly than the water; wind blows from the land to the water
