causes of weather
what causes weather? Weather processes such as wind, clouds, and precipitation are all the result of the atmosphere responding to uneven heating of the Earth by the Sun. The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures). The atmosphere thus becomes a giant heat engine, continuously driven by the sun.
BIG IDEAS Weather affects the way we live, what we eat and wear and how we feel. We can describe weather conditions by using mathematics. LESSON 2 What Makes Weather? BIG IDEAS The sun heating the earth and its atmosphere causes the weather. We feel weather as wind, heat or cold, and humidity in the form of rain, ice and snow.
