Core Elements of Weather:

• Temperature: A measure of heat energy in the air driven by uneven solar heating of the Earth.
• Air Pressure: The weight of the atmosphere. High-pressure systems bring clear skies, while low-pressure systems cause rising air, clouds, and storms.
• Wind: Air movement caused by pressure differences as warm air rises and cool air sinks.
• Humidity: The amount of moisture or water vapor in the air. Warm air holds more moisture than cold air.Precipitation: Condensed water vapor such as rain, snow, or sleet that falls when air cools to its dew point.
