| Question | Answer |
| how do you measure relative humidity | a psychrometer |
| what two conditions are necessary for cloud formation | cooling of the air and the presence of particules in the air |
| what are the large clouds called that often produce thunderstorms | cumulonimbus clouds |
| what do we call any form of water that falls from clouds | precipitation |
| What type of air mass produces cold,dry air that affects the northern United States | continental polar air mass |
| What kind of weather would a continental tropical air mass that formed over northern Mexico produce in the southwestern United States | hot,dry |
| From which direction to which direction do the prevaling westerlies,the major wind belt over the continental United States push air masses | west to east |
| What type of front forms when a rapidly moving cold air mass overtakes a slow moving warm mass | cold front |
| What is the major difference between cyclones and anticyclones | cyclones-low air pressure (weather clouds,wind and precipition)anticyclones-high pressure(weather dry,clear) |
| what type of weather is generally associated with an anticyclones | dry clear weather |
| What is a funnel shaped cloud that touches Earth's surface called | tornadoes |
| In what types of clouds do thunderstorms form | cumulonimbus clouds |
| What states are included in the designation Tornado Ally | nebraska,iowa,kanas,oklahoma,texas |
| where do hurricanes typically form | over warm ocean water as a low pressure area |
| What is a dome of water that sweeps across the coast where a hurricane makes landfall | a storm surge |
| what are conditions within the "eye" of the hurricane | calm,clear |
| what is a storm | is a violent disturbance in the atmosphere |
| what are some of the best places to seek protection during a tornado | storm shelter,basement of a well built building(if outside lie in a ditch) |
| what are examples of safe places to be during a thunderstorm | indoors,away from water |
| when people are asked to evacuate during a hurricane watch,what are they being asked to do | leave the area imediately |
| what do we call scientists who study weather and try to predict it | meteorologists |
| what sources of weather data would enable a meteorologists to follow the path of an approaching thunderstorm | maps,charts,computers,radar,and satellites |
| what are isobars and what do they connect | isobars are lines joining places on the map that have the same air pressure |
| within what types of clouds do tornadoes form | thick cumulonimbus clouds |
| what is the process that allows clouds to form when water vapor in the air becomes liquid | condensation |
| what is the process in which water vapor in the air changes from a liquid to a gas | evaporation |
| what is a cloud that forms near the ground and is called a stratus cloud | fog |
| what type of air mass can bring thunderstorms to the untied states in the summer | maritime tropical |
| what is a long lasting storm that begins over a warm surface of the ocean and has winds of at least 119 kilometers per hour or higher | hurricane |
| hot,dry air moves into the southwest in summer from what kind of air mass | continental tropical |
| what is the symbol for an isotherms | isotherms-equall temperature isobars-equall pressure |
| atmosphere | is the envelope of gases that surrounds the planet |
| air pressure | is the result of the weight of a column of air pushing down on an area |
| coriolis effect | is the effect of earth's rotation on the the direction of winds and currents |
| conduction | is the heat transfer within a materials that are touching |
| covection | is a heat transfer within a material or between materials that are touching |
| radiation | is transfer of energy through space |
| greenhouse effect | is the process by which gases hold heat in the air |
| global winds | are winds that blow steading from specific directions over long distances |
| barometer | is an instrument that is used to measure air pressure |
| weather | is the condition of earth's atmosphere at a particular time and place |
| what causes convection in the atmosphere | upwar movement of warm air downwar movement of cold air |
| what is the purpose of the ozone layer | it absorbs solar radiation and and ultraviolet radiation |
| what layer of the atmosphere does weather occur | troposphere |
| what happens to the air prssure as you increase in altitude | it decreases and so does density |
| scientists divide the earth's atmosphere into four main layers,classified according to changes in blank. | temperature |
| when a warm air mass and a cold air mass meet and neither can move the other,what front is fromed | stationary front |
| when a warm air mass overtakes a cold air mass it forms a what front | warm front |
