Elements of Weather
Weather is described using several elements, including temperature, humidity, wind, precipitation, and air pressure.
Core concept
Temperature measures how hot or cold the air is, while humidity measures the amount of water vapour present in the air.
How it works
Wind refers to the movement of air, described by its speed and direction, which can range from a gentle breeze to a strong storm.
Why it matters
Precipitation refers to water falling from the sky, like rain, snow, or hail, which is essential for replenishing water sources on Earth.
Key detail
Air pressure, the weight of air pressing down on Earth's surface, influences weather patterns - low pressure often brings rain, while high pressure often brings clear skies.
