weather test

Which surface heats faster?

sand

Why? What is this called?

Specific heat- the amount of energy used to heat up something

sand has low specific heat

Which surface cools down faster?

sand

What causes wind?

The unequal heating and cooling of earth

What is convection?

The transfer of heat energy in a gas or liquid (heat ries, cools sinking)

What is the difference between a land and a sea breeze?

Sea Breeze- the breeze/ wind that comes from the sea

Land breeze- the breeze/ wind that comes form the land

How are global winds and ocean currents connected?

Because global winds push ocean currents

In what motion do ocean currents move in - what is this called? How does it look on a map?

1. Moves in a circular motion called a  gyre.

2. Gyres are driven by convection cycles

mP

-marine polar

-Form of Water

-Brings wet weather

mT

-marine Tropical

-Form over water

Brings wet weather

cP

-Continetal polar

-Form over land

Brings dry weather

cT

-Continental Tropical

-Form over land

Brings Dry weather

Can you identify each of the four weather fronts?

1. Cold front

   1. Moves quickly

   2. Brings cold weatherq

2. Warm front

   1. Brings warmer weather

   2. Brings drizzly rain followed by clear weather

3. Stationary front

   1. Brings many days of cloudy wet weather

   2. Does not have enough force to move

4. Occluded front

   1. Brings cool temperatures and large amounts of rain and snow

What are the four ingredients of a hurricane?

1. Warm ocean temp > 80^oF

2. Dry air moves over onto warm ocean

3. Water evaporates from the ocean, warm moist air rises, cools as it rises and creates massive rain clouds.

4. NE Trade Winds cause the storm to start rotating.

What happens to a hurricane when it hits land?

1. The hurricane loses its fuel 

   1. Its fuel is water

Why are the following important when studying hurricanes?

Wind speed

Wind direction

Air pressure

Because they are how a hurricane moves around
