| Describe air pressure? | How much the air above you weighs down on you is air pressure |
| What happens to air pressure as altitude increases? | Air pressure decreases |
| Describe jet streams? | Narrow belts of high speed winds |
| What are green house effect | Where heat and sunlight is let in but warmth can not escape |
| Explain the 3 ways that heat is transferred? | Thermal radiation, convection and conduction |
| Where do trade winds flow towerad? | At every 30 degrees and along the equator |
| What does the Coriolis Effect make the winds do? | Due to the earths rotation it causes winds to curv |
| Describe Doldroms? | A low pressure area around the equator |
| What is the ozone layer, where is it found? | The ozone layer is found in the stratosphere, and protects us from harmful U.V rays |

| What is the atmosphere? | |
| List the three global winds and the 2 calm areas? | Polar easterlies, Westerlies, local winds, doldrums, and horse latitdues |
| What is global warming? | due to the greenhouse effect warmth does not escape the earth so temperture is gradualy increasing |
