Clouds are classified by their altitude.
Cumulus Clouds These clouds look like fluffy, rounded piles of cotton. They from less than 2 km above the ground but can grow to reach as much as 18 km. Cumulus clouds usually indicate fair weather.
These clouds form in flat layers. Stratus clouds usually cover all or most of the sky. As stratus clouds thicken, they may produce drizzle, rain or snow.
Cirrus Clouds These clouds look wispy and feathery.\ They form only at high levels where temperatures are very low. Cirrus clouds are made of ice crystals. They indicate a change in weather within 24 hours.
