Question | Answer |
---|---|
Describe the 4 main clouds based on formation, altitude, and weather. | Cumulus:3,000 m. high, forms when warm air rises, indicates fair weather. Cirrus: 8,000 m. high,form when wind is strong, indicates change in weather. Stratus:1,000m high,formed when gentle lifting of the air into the atmosphere, and light to heavy rain |
Describe condensation and evaporation | Evaporation is when liquid water changes to a gas. Condensation is the change of state from a gas to liquid |
How are humidity, saturation, and condensation related | They all change a gas to liquid |
How are the 4 types of precipitation different from each other. | They are different sizes and form differently |
What are air masses and how are they characterized | Air masses are large bodies of air and there are characterized by moisture and temputure |
List the types of air masses and describe each based on their symbols | Martine tropical, forms over water, low pressure, warm, and humid Martine polar,forms over land, high pressure, cool and wind |
Describe the densities between warm and cool air. Why is this fact important in understanding fronts? | Warms air rise so it''s less dense and cool air sinks so it's very dense |
Describe the movements of air masses for each of the fronts. | Martine tropical: forms over water, low pressure, warm and humid Martine polar: forms over land, high pressure, cool and windy Continental tropical: forms over land, high pressure Continental polar:forms over water, low pressure |
What type of weather does each front bring | Cold front:Brings brief storms and cooler weather Warm front:Sometimes accompanied by precipitation Stat. Front:Brings long periods of precipitation Occluded front: Brings precipitation |
How are cyclones and anticyclones different | Cyclones: low pressure and warm Anticyclones: high pressure and cool |
How are tornadoes and hurricanes different | Tornadoes:forms over land and touches the ground Hurricanes:forms over water, tropical |
How do you stay safe from hurricanes, tornadoes, floods, and lighting | You have to stay indoors, avoid staying in high places, don't touch metal, have a radio, stay away from windows and doors, and drills |
How do weather ballons help in predicting the weather | Carries electronic equipment that measures weather conditions above Earth's surface |
How is an isobar and barometer related | They both have something to do with air pressure. One connects points or measures air pressure |
How is an isotherm and a thermometer related | The both have to do something wih temputure. One measures temp. at a certain and time and place |
How is technology used for weather predicated | The Doppler radar and the weather satilities |
How do you know which direction a front is moving | The way it's heading is the location it is |
Where is tornado alley and why is it there | It's in U.S, it's there because lots of Tornadoes in the area |
Describe the temp. and precipitation in the tropical forest | The percipitation is really rainy. The temp. is really humid |
