Answer 2

Two types of clouds that are commonly responsible for precipitation are cumulonimbus and nimbostratus clouds. 'Cumulonimbus' clouds create heavy downpours and are common in tropical and temperate regions. Nimbostratus clouds are thick and can be responsible for snow, ice or rain. These clouds produce moderate to heavy precipitation for prolonged periods.
