Weather Overview En
| Term | Definition |
|---|---|
| Atmosphere is | layers of gases surrounding the Earth, where weather is made (troposphere) |
| Atmosphere does | distribute Earth's energy through wind patterns |
| Weather is | current air conditions |
| Climate is | general patterns of weather over longer periods of time |
| The suns energy can be | refracted, scattered, reflected, absorbed |
| Variables that influence weather (6) | temperature, air pressure, moisture, air movement, cloud covering, precipitation |
| Temperature/Heat | measure of average kinetic energy of a material |
| Kinetic energy | energy of an object in motion |
| When temperature is hotter, particles move | more/faster |
| Potential energy | energy at rest (potential to do work) |
| Heat travels three ways | Convection, Conduction, Radiation |
| Convection | Hot material expands and rises, cool material contracts and sinks |
| Conduction | movement of heat from hot to cold surfaces, must be touching for heat to travel |
| Radiation | energy that moves via waves/particles |
| Air pressure | measure how compressed particles in the air are |
| 1 atm | pressure seen at sea level under the weight of the entire atmosphere |
| Dew point | temperature the air needs to be for dew or condensation to form |
| Type of air that holds more moisture | warmer air |
| Type of air with a higher dew point | warmer air |
| Relative humidity | percentage of moisture in the air |
