Marano Weather 2
| Question | Answer |
|---|---|
| air | mix of gases many of tiny molecules that press against whatever is holding it in place |
| air pressure | all the air molecules pushing on you |
| The higher up you are the (lower, higher) the air pressure | lower |
| barometer | measures air pressure |
| mercury barometer | long glass tube filled with mercury and placed, open end down, in a dish or mercury |
| aneroid barometer | a flat metal box that has a vacuum chamber, the higher the pressure the more the box is squeezed together |
| atmosphere (atm) | average pressure exerted by the Earth's atmosphere at sea level |
| Torr | pressure needed to push a column of Mercury up 1 mm or millibar (mb) |
| Rising pressure usually signals the approach of ____ weather | fair |
| Falling pressure mean that _____ | a storm is approaching |
| moisture= ____ presssure | low |
| The greater the temperature, the _____ the pressure. | lower |
| High pressure will always move to ____ pressure. | low |
| Horizontal movement of air parallel to the Earth's surface is ________. | wind |
| two parts in which wind is measured | speed and directions |
| wind speed is measured with | an anemometer |
| Wind speed is measured in | knots |
| wind direction is measured with a | weathervane |
| weathervane points to where the wind is (coming from, going) | going |
| Wind is named by whre the wind (came from, is going) | came from |
| Water needs a lot (more or less energy) to raise its temperature 1 degree and a lot more energy needs to be lost for it to lose 1 degree C. | more energy |
| By day, sea breeze water is _____, land is _____. | colder, warmer |
| By day sea breeze- pressure moves from (high, low) pressure to (high, low) pressure causing a sea breeze. | high, low |
| The Equator is hot and wet= ____ pressure. Winds will ____ the Equator | low, come to |
| Lighter air from the Equator then (rises, drops) | rises |
| As the air from the Equator rises, it will cool and drop to form a _____. | convection cell |
| Coriolis effect | Because the Earth rotates, winds are deflected to the right in the Northern Hemisphere, and deflected to the left in the Southern Hemisphere |
