| Question | Answer |
|---|---|
| List the examples of local winds | Polar easterlies westerlies easterlies |
| What are auroras and where are they found? | Shimmering lights found in the ionosphere (thermosphere) |
| Our ozone layer absorbs which type of harmful radiation from the sun? | Thermal gasses |
| Which global wind blows away from the poles to the west? | Westerlies |
| What are the 2 most abundant gases found in the air? | Nitrogen and oxygen |
| Describe air pressure | Gravity pulls molecules to the surface causing air pressure |
| What happens to air pressure as altitude increases? | Air pressure decreases |
| Describe jet streams | They are fast movement of streams that can track storms that are coming |
| What is the greenhouse effect? | Process by which gasses in the atmosphere absorb thermal energy |
| Explain the 3 ways that heat is transfered | Convection-energy through a liquid or gas Conduction-material is heated by direct contact Radiation-EM waves ( can't touch) |
| Where do trade winds flow toward? | The equator |
| What does the Coriolis Effect make the winds do? | It produces patterns of circulation |
| Describe the doldrums | Trade winds from the northern and southern hemisphere meet up in an area around the equator |
| What is the ozone layer? Where is it found? | The outside surrounding layer around earth that protects us from ultra violent rays from the sun The ousted layer of the earth |
| Describe the thermosphere | Uppermost layer of the atmospheretempurature increases here due to the suns radiation |
| What parts of the earth cools off faster and heats up faster? | At the poles it cools faster and at the equator it warms up faster |
| What does this unequal heating create? | Wind precipitation and clouds |
| What is smog? | A fog that is combined with smoke and other industrial pollutants |
| Describe the movement of convection currents | It goes in a pattern of circulation |
| Which instrument measures air pressure? | Barometer |
| What is significant about the troposphere? | Weather happens there |
| What kind of ways have humans created air pollution? | Burning fossil fuels because of cars and factorization |
| What is another name for the distance above sea shore? | Shoreline |
| What are globals winds? | Winds that blows causing ripples in surface water covered global winds from the equator and back |
| What does the name of wind tell you? | Where they are going |
| How much of the suns energy actually hits the earth? | 2 billionths |
| What property are the atmosphere layers based on ? | Temperature |
| Which calm area located around 30 degrees north and south latitude? | Horse latitudes |
| What is the atmosphere? | A mixture of gasses that surround the earth's layer |
| List 3 global winds and 2 calm areas | Westerlies polar easterlies doldrums horse latitudes trade winds |
| What is global warming? | Increase in greenhouse gasses in atmosphere may have caused this increase in temperature |
| If air mass increases what happens to density? | Density decreases |
| What type of winds blow over short distances? | Trade winds |
| How are all winds created? | The movement of air caused by differences in air pressure |
| How much oxygen and carbon dioxide is found in our air? | O=21% CO2=less than 1% |
| Which global winds blows away from the poles to the west? | Polar easterlies |
| What is the most atmospheric gas? | Nitrogen |
| Describe the movement of convection currents? | With a heat source cold sinking dense air pushes warm light less dense air continuing in a cycle |
| What is another name for the distance above sea level? | Elevation and altitude |
