Science: Weather
| Question | Answer |
|---|---|
| What are Convection Currents | Help the air move around the Earth. Warm air at the equator moves towards the poles, while cold air at the poles travels to the equator. This creates a convection current. |
| Maritime Tropical | Forms: Water Humidity: Wet Temperature: Warm |
| Maritime Polar | Forms: Water Humidity: Wet Temperature: Cold |
| Continental Polar | Forms: Land Humidity: Dry Temperature: Cold |
| Continental Tropical | Forms: Land Humidity: Dry Temperature: Warm |
| Cloud Formation | Clouds form because of CONDENSATION which is when water turns from a gas into a liquid |
| What is Weather | The minute by minute changes in the atmosphere that include: temperature, wind speed, wind direction, pressure, humidity, precipitation |
| Cold front | Occurs when Cold air is traveling towards and meeting warm air |
| Warm Front | Occurs when warm air is traveling towards and meeting cooler air |
| Stationary Front | Occurs when warm and cold air meet and don't move |
| High Pressure | Clear, sunny skies, low to no wind, stable atmospheric conditions |
| Low Pressure | Windy, cloudy, unstable atmospheric conditions |
| Stationary Causes | Light rain, humidity, thin clouds |
| Warm Causes | Light rain, warmer temps, humidity, thin clouds |
| Cold Causes | Thunderstorms, very cloudy skies, high winds, cooler temps |
| Land Day | Warmer than sea, Land air goes up, cools down then goes to sea air |
| Land Night | Cooler than sea, Land air goes towards the sea air (Land breeze) |
| Sea Day | Cooler than Land air, Sea air goes towards the Land air (sea Breeze) |
| Sea Night | Warmer then Land air, Sea air goes up , cools down and goes to Land air |
| Humidity | the measure of the amount of water vapor in the air |
| Weather Front | The boundary between two air masses |
| Air Pressure | the force exerted by the weight of the atmosphere’s molecules on a surface |
| Air Mass | Body of air that takes on the characteristics of the surface below it. Consists of temperature and moisture |
| Climate | The weather conditions over a specific place for a LONG period of time - 30+ years |
