| Question | Answer |
|---|---|
| List the examples of local winds. | land breeze, ocean greeze |
| What are the auroras and where are they found? | polar regions these ions radiate energy as shimmering lights called auroras. The Ionopsphere |
| Our ozone layer absorbs which type of harmfull raciation from the sun? | UV rays |
| How much oxygen and carbon dioxide is found in our air? | Oxygen: 21% 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. | Oxygen and nytrogen |
| Describe air pressure. | is the measure of the force with which air molecules push on a surface. |
| What happens to air pressure as altitude increases? | as altitude (distance from sea level) increases, air pressure decreases. |
| Describe jet stream. | are narrow belts of high-speed winds that blow in the upper troposphere and lower stratosphere. |
| What is the green house effect? | s the process by which gases in the atmosphere, such as water vapor and carbon dioxide, absorb thermal energy and radiate it back to Earth. |
| Explain the 3 ways that heat is transferred. | Convection, Radiation, Thermal conduction |
| Where do trade winds flow towared? | the equator |
| What does the Coriolis Effect make the winds do? | the Coriolis effect makes winds curve |
| Describe the doldrums. | The trade winds of the Northern and Southern Hemispheres meet in an area around the equator called the doldrums. |
| What is the ozone layer? Where is it found? | the ozone layer is a thin layer of gas that keeps out harmful rays from the sun. Stratosphere |
| Describe the Thermosephere. | In the thermosphere, temperature again increases with altitude. Atoms of nitrogen and oxygen absorb high-energy solar radiation and release thermal energy, which causes temperatures in the thermosphere to be 1,000°C or higher. |
| What is the most common atmoshphere gas? | Nyrogen |
| What parts of the Earth cools off faster and heats up faster? What does this unequal heating create? | The land |
| What is smog? | Vehicle exhaust reacts with air and sun light to form ozone. Ozone reacts with vehicle exhaust to form smog. |
| Describe the movement of convection currents. | Cool air is denser it sinks. As cool air sinks. it pushes warm air up. cool air is eventually heated by the Earth’s surface and begins to rise again. This cycle of warm air rising and cool air sinking causes a circular movement of air. |
| Which instrument measeres air pressure? | |
| What is significant about the Trophoshere? | we live in it and it has enough oxygen that we can live in it |
| What kind of ways have humans created air polution? | human sources include carbon monoxide, dust, smoke, and chemicals from paint and other substances. In urban areas, vehicle exhaust is a common source of primary pollutants. |
| What is another name for the distance above sea level? | altitude |
| What are global winds? | The combination of convection cells found at every 30 degrees of latitude and the Coriolis effect produces patterns of air circulation called global winds. |
| What does the name of a wind tell you? | it happens all over the globe |
| How much of the the sun's energy actually reaches the Earth? | 50% |
| What property are the layers of the atmoshere based on? | |
| Which calm area is located around 30 degrees north and sounth latitued? | |
| What is the atmoshere? | The atmosphere is a mixture of gases that surrounds Earth. In addition to containing the oxygen you need to breathe, the atmosphere protects you from the sun’s damaging rays. |
| List the 3 global winds and the 2 calm areas. | polar easterlies, westerlies, trade winds. doldrums and horse latitudes |
| What is global warming? | scientists have become concerned about data that show that average global temperatures have increased in the past 100 years. Such an increase in average global temperatures is called global warming. |
| If air mass increases what happens to denstiny? | density increases |
| What type of winds blow over short distences? | local winds |
| How are all winds created? | differences in air pressure |
