SECONDARY IDEAS:Weather is caused by warmer air interacting with

cooler air.Convection currents are caused by less dense air

rising and more dense air sinking to fill in the “hole”.

Warmer air is LESS DENSE than cooler air. Less dense matter “floats” on top of more dense matter.

DENSITYLESS DENSE RISES!

What did I just say?

In sentence form, write what I recently said about DENSITY.

Now, ask your neighbor to READ YOUR STATEMENT and then to make a

meaningful comment about DENSITY.In sentence form, write what I recently said about how WARMER MATTER AND COOLER AIR interact.

LINED PAPER…

Hurricane Formation

In order for a hurricane to form, there must be a supply of warm, moist air for a long period of time.

• Formation begins in the tropic regions (5 to 20 degrees latitude).

• Energy comes from condensing water vapor due to unstable humid air rising.

When water vapor condenses to liquid water it releases 540 kcal per mole.

When liquid water freezes to ice, it only lets off 80 kcal per mole.

•For a hurricane to form it must begin to rotate (Coriolis Force).

-Hurricanes rotate counterclockwise in Northern Hemisphere.

-Hurricanes rotate clockwise in Southern Hemisphere.
