| Question | Answer |
|---|---|
| What is unique about our solar system's atmosphere? | It contains substantial amounts of oxygen. |
| What was contained in the earliest atmosphere of Earth? | Helium and hydrogen. |
| What happened to the atmosphere after the moon formed? | The atmosphere contained mainly carbon dioxide, carbon monoxide and water vapor. |
| What changed the atmosphere, reduced the amount of carbon dioxide and added oxygen? | Photosynthesis. |
| What creates weather? | Transfer of energy (heat) between the Earth's surface and atmosphere. |
| What is the major cause of weather? | Convection, which is when warm air rises because it's less dense and cold air sinks because it's more dense. |
| How does precipitation occur? | It occurs when the cloud droplets join together and grow large and heavy enough to fall from the cloud. |
| What does H mean on a weather map? | H (High barometric pressure) means air is sinking, so weather will be fair and clear. |
| What does L mean on a weather map? | L (Low barometric pressure) means air is rising (convection), so weather will be poor, cloudy and possibly have precipitation. |
| Which way do High Pressure Systems spin? Which way do Low Pressure Systems spin? | Clockwise; Counterclockwise. |
| What is usually found on the right side of low pressure stems? What is usually found on the left side? | Warm fronts; Cold fronts |
| Wind always moves from what pressure to what pressure? | High pressure to Low pressure. |
| Warm air is less or more dense than cold air? | Less dense |
