Weather describes short-term atmospheric conditions, while climate refers to long-term weather patterns in a region.
Weather is driven primarily by the uneven heating of Earth's surface by the sun, creating differences in air pressure and temperature.
The water cycle describes the continuous movement of water through evaporation, condensation, and precipitation.
Earth is divided into major climate zones, including tropical, arid, temperate, continental, and polar.
Long-term shifts in global temperature, driven by increased greenhouse gas concentrations, are altering ecosystems and weather patterns worldwide.
