Study Guide
| Question | Answer |
|---|---|
| List the examples of local winds. | Sea breezes and land breezes |
| What are the auroras and where are they found? | The auroras are a group of shimmering lights. They are fond in the ionosphere. |
| Our ozone layer absorbs which type of harmful radiation from the sun? | Ultra Violet(UV) rays |
| How much oxygen and carbon dioxide is found in our air? | Oxygen- 21%, Carbon Dioxide- less than one percent. |
| 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. | The measure of the force with which air molecules push on a surface. |
| What happens to air pressure as the altitude increases? | The air pressure decreases |
| Describe jet streams. | Narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere. |
| What is the greenhouse effect? | By which gases in the atmosphere such as water vapor and carbon dioxide, absorb thermal energy and bring it back to he earth. |
| Explain the 3 ways that heat is transferred? | Conduction-the direct contact of a cold object to a warm one. Convection-transfer of energy by circulation or movement of a gas. Radiation-transfer of energy as electromagnetic waves. |
| Where do trade winds flow toward? | Equator. |
| What does the Coriolis Effect make winds do? | It makes winds curve because of the Earth's rotation. |
| Describe the doldrums. | The trade winds of the Northern and Southern Hemisphere meet in an area around the equator. Very light or calm winds here. |
| What is the ozone layer? Where is it found? | A layer of thin gases that protects the Earth from harmful UV rays. It is found in the stratosphere. |
| Describe the thermosphere. | Aurora Borealis found here. Also the temperature is highest here. |
| What is the most common atmospheric gas? | Nitrogen |
| What parts of the earth cools up faster and heats up faster? What does this unequal heating create? | The land cools up faster and heats up faster.This creates winds. |
| What is smog? | A react with ozone and exhaust. |
| Describe the movement of convection cells? | With a heat source cold dense air pushes warm air up. |
| Which instrument measures air pressure? | Barometer. |
| What is significant about the troposphere? | It is where we live and where weather takes place. |
| What kind of ways have humans created air pollution? | Burning fossil fuels;exhaust,and chemicals. |
| What is another name for distance above sea level? | Elevation and altitude. |
| What are global winds? | Combination of convection cells at 30 degrees winds blow across long distances. |
| What does the name of a wind tell you? | The direction that it is coming from. |
| How much of the sun's energy actually reaches the earth? | 2 billionths |
| What property are the layers of the atmosphere based on? | Temperature. |
| Which calm area is located around 30 degrees north and south latitude? | Horse latitude. |
| What is the atmosphere? | A mixture of gases that surround the earth(layer) and protect us from UV rays |
| List 3 global winds and 2 calm areas? | Global winds:Trade winds,Polar easterlies and westerlies. Calm area: Doldrums,Horse Latitude |
| What is global warming? | A gradual increase in average global temperatures. |
| If air mass increases what happens to density? | The density increases |
| What type of wind blows over short distance? | Local winds. |
| How are all winds created? | Unequal heating of Earth's surface. |
