HOW DO THEY HAPPEN?

• They get their energy from humid air

STEP 1

• Warm air rises and forms a cumulus cloud.
• Water vapor releases energy when condensed
• Energy increases air motion
• Cloud continues to build up

STEP 2

• Ice particles form
• Particles begin to grow, increasing size
• They begin to fall and pull cold air down with them
• This downdraft brings heavy rain or hail

STEP 3

• The downdraft can spread out and block warm air moving upwards
• The storm slows down and ends

LIGTHNING

• Happens between a positively charged area and a negative area

THUNDER

• Rapidly moving air

• The vibrations are a cause of a rapid expansion of air
