Stages in a Thunderstorm
answer
Developing stage, mature stage and dissipating stage.
Unlock the answer
question
Developing Stage
answer
Warm moist air moves up into the atmosphere and forms a thunderstorm cloud when it hits cool air.
Unlock the answer
question
Mature Stage
answer
Cloud grows and becomes too heavy to hold any more water so it precipitates and causes a downdraft.
Unlock the answer
question
Dissipating Stage
answer
Storm starts to fade when all the precipitation is released and the downdraft is greater than the updraft.
