Being a dedicated tutor and a person who has nothing much to do during e weekends
I decide to try and solve my dear inquisitive student's question

"how are tornadoes and hurricanes form?"

Tornadoes


Tornadoes form where warm, moist air and cold, dry air meet and begin to create updrafts that develop into massive rotating cumulonimbus clouds or supercells.

Sometimes a spinning column of air called a vortex forms within these clouds. When this vortex becomes visible as a funnel cloud and reaches the ground, a tornado is created.

Hurricane
The generic, scientific term for these storms, wherever they occur, is tropical cyclone.

Hurricanes only form over really warm ocean water of 80°F or warmer. The atmosphere (the air) must cool off very quickly the higher you go. Also, the wind must be blowing in the same direction and at the same speed to force air upward from the ocean surface. Winds flow outward above the storm allowing the air below to rise. Hurricanes typically form between 5 to 15 degrees latitude north and south of the equator



Quite cool. =) but don't think I can explain all these to him. LOL
