Meteorology is the study of the climate and weather
Clouds form when (invisible) water vapor turns into visible water droplets or ice, it then becomes gas.
The rain occurs because the clouds have water droplets in them, they condense into each other and then fall to earth as rain.
Thunder is created when lighting passes through the air.

A meteorologia é o estudo do clima e do tempo
Nuvens se formam quando o vapor de água (invisível) se transforma em gotículas de água visíveis ou gelo, então se transforma em gás.
A chuva ocorre porque as nuvens têm gotículas de água, elas se condensam umas nas outras e caem na terra como chuva.
O trovão é criado quando a luz passa pelo ar.
