GenSci 706 q1
| Question | Answer |
|---|---|
| The weight of the air pushing down on the Earth is called what? | air pressure |
| An anti-cyclone can occur in a _____ pressure area. | high |
| The tendency of a moving object to curve due to the Earth's rotation is called what? | The Coriolis effect |
| A cyclone can occur in a _____ pressure area | low |
| The temperature at which the air becomes saturated is called what? | The dew point |
| The amount of moisture in the air is called what? | humidity |
| The study of the atmosphere and the weather is called what? | meteorology |
| The moisture that falls from the clouds is called what? | precipitation |
| What element affects weather the most? | Temperature |
| What provides the energy needed for weather changes to occur? | The sun |
| Warm air does what? | It rises. |
| The general flow of air from the poles to the equator occurs where? | At the surface of the earth |
| If you are in _________, airborne objects tend to curve to the right. | The Northern hemisphere |
| What instrument is used to measure air pressure? | A barometer |
| What direction does air move around an anticyclone? | clockwise |
| What does air do as it cools down? | It sinks. |
| What instrument is used to determine the direction of air movement? | A wind vane |
| The general flow of air from the equator to the poles occurs where? | In the upper troposphere. |
| An instrument for measuring the speed of the wind is the ______ | anemometer |
| The primary cause of weather is the _______ in ___________ around the earth. | changes in temperature |
| The troposphere receives most of its heat energy directly from what? | The ground |
| Two standard scales for measuring temperature are: | Celsius Fahrenheit (Be sure you know how to spell them.) |
| Water freezes at __ degrees Celsius and at ___ degrees Farenheit. | 0 C 32 F (Pay attention on the test to whether they're asking you about C or F.) |
| Water boils at ___ degrees Farenheit. | 212 |
| Local winds can be caused by ________ heating of the Earth's surface. | uneven |
| Which air is more dense, cold air or hot air? | Cold |
| The overall global circulation of air is caused by ______ equatorial air, ______sinking polar air, and deflection of air to the ______ in the Northern Hemisphere. | The overall global circulation of air is caused by RISING equatorial air, SINKING polar air, and deflection of air to the RIGHT in the Northern Hemisphere. |
| A narrow band of high-velocity air in the upper troposphere is called the _________ . | jet stream |
| What is the standard sea level pressure? | 14.7 lb/sq inch |
| Areas of sinking cold air generally have _________ pressure and ______ weather. | high pressure sunny (or good or clear or fair) weather. |
| The measure of water vapor saturation of air is called what? | Relative humidity |
| When air is cooled, the relative humidity will do what? Why? | It will increase, because cooler air has less capacity to hold moisture, so the cooling air will be like a shrinking cup holding the water. It will become more full, which is higher "relative" humidity. |
| Rain falling through sub-freezing calm air will turn into what? | Sleet |
