| Question | Answer |
|---|---|
| List the examples of local winds | sea and land breeze |
| what are the auroras and where are they located | radiate energy that shimmers is located in the ionsphere |
| our ozone layer absorbs which type of of harmful radiation from the sun | uv rays |
| how much oxygen and carbon dioxide is found in our air | 21% oxygen and less than1% carbon dioxide |
| which global wind blows away from the poles to the west | polar easterlies |
| what are the 2 most abundant gases found in the air | nitrogen and oxygen |
| describe air pressure | mixture of gases that protect the earth from the sun |
| what happens to the air pressure as altitude increases | pressure decreases as altitude increases |
| describe jet streams | narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere not regular paths,affect the movement of storms 400 km/hr |
| what is the greenhouse effect | the earth radiate the heat from the sun the radiate it back |
| explain the 3 ways that heat is transferred | conduction- direct touch radiation-can't touch convection- heat from liquid or gas |
| where do trade winds flow torward | toward the equator |
| what does the Coriolis effect make the winds do | go in circular patterns due to the rotation of the earth |
| discribe the doldrums | trade winds of the northern and southern hemisphere meet in the area around theequator |
| what is the ozone layer | layer that protects us from heating of the sun |
| where is it found | in the statosphere |
| describe the troposhere | turning or change gases turn or mix |
| what is the most common atmospheric gas | nitrogen |
| what parts of the earth cools off faster and heats up faster | land |
| what does this unequal heating create | air pressure or winds |
| what is smog | sunlight reacts with the ozone and vehicle exhaust |
| describe the movement of convection currents | cycle of warm air rising and cool air sinking moving in circles |
| which instrument measures air pressure | a barometer |
| what is significant about the troposphere | whether occurs |
| what kind of ways have human created air pollution | using cars that run on gas, burning fossil fuels |
| what is another name for the distance above sea level | elevation or altitude |
| what are global winds | combination of convection cells found at every 30 degrees of latitude and the Coriolis effect produces patterns of air circulation |
| what does the name of the wind tell you | what direction its coming from |
| how much of the sun's energy actually reaches earth | 2 billionths of it |
| what property are the layers of the atmosphere based on | based on the temperature |
| which calm area is located around 30 degrees north and south latitude | horse latitudes |
| what is the atmosphere | a mixture of gases that protect life from the dangerous chemicals from outer space |
| list the 3 global winds and the 2 calm areas | polar easterlies, westerlies, trade winds, and doldrums, horse latitudes |
| what is global warming | the belief that the earth is getting warmer everywhere |
| if air mass increases what happens to density | it decreases |
| what type of wind blows over short distances | local winds |
| how are winds created | movements of air caused by the differences in air |
