Study Guide
| Question | Answer |
|---|---|
| List the examples of local winds? | Valley breezes and Mountain breezes. |
| What are auroras and where are they found? | Formed by charged particles in the ionosphere. In the upper mesosphere and the lower thermosphere |
| Our ozone layer absorbs which type of harmful radiation from the sun? | The ozone layer absorbs Ultra Violet radiation from the sun. |
| How much oxygen and carbon dioxide is found in our air? | 21% |
| Which global wind blows away from the poles to the west? | Westerlies |
| What are the 2 most abundant gasses found in the air? | Oxygen Nitrogen Gas |
| Describe air pressure? | How tightly packed together air molecules are the closer to the core the more pressure there is. |
| What happens to air pressure as altitude increases? | pressure decreases |
| Describe Jet streams? | Narrow belts of high speed winds that blow in the upper troposphere and lower stratosphere. |
| What is the Green house effect? | sunlight and heat can come in but the heat is trapped. |
| Explain the 3 ways that heat is transferred? | Conduction, |
| Where do Trade winds flow toward? | Equator and doldrums |
| What does the Coriolis Effect make the winds do? | Move in a circular information |
| Describe the doldrums? | A spot in the middle of where both trade winds blow with little to no wind for sail or anything. |
| What is the ozone layer? Where is it found? | The ozone layer protects us from harmful U.V. rays. It is in the mesosphere |
| Describe the Thermosphere? | Hottest part of the atmosphere. |
| What is the most common atmospheric gas? | Nitrogen Gas |
| What part of the Earth heats up faster and cools off faster? What does the unequal heating create | The ground cools off faster and heats up faster. The unequal heating creates Local winds. |
| What is smog? | A mixture of smoke and fog |
| Describe the movement of convection currents? | cold sinking dense air pushes warm light less dense air continues in a cycle |
| Which instrument measures air pressure? | Barometer |
| what is significant about the troposphere? | We live there and all of our weather takes place in this layer of the atmosphere |
| What kind of ways have humans created air pollution? | By: Burning fossil fuels and smoking |
| What is another name for the distance above sea level? | Altitude or Elevation |
| What are Global winds? | convections cells at every 30 degrees latitude Blow across long distances |
| What does the name of the wind tell you? | The direction it's going |
| How much of the sun's energy actually reaches the Earth? | 2 billionth |
| What property are the layers of the atmosphere based on? | temperature |
| Which calm area is located around 30 degrees north and south latitude? | Trade winds |
| What is the atmosphere? | A mixture of gasses that protect the Earth from harmful U.V rays and space debris |
| List the 3 Global winds and the 2 calm areas? | Westerlies, Easterlies, and Polar |
| What is Global warming? | The increase in average temps on Earth |
| If air mass increases what happens to density? | Decreases |
| What type of winds blow over short distances? | Local winds |
| How are all winds created? | Unequal heating |
