Why do you think Texas weather changes so often? Do you believe what the weatherman says on the

news? Why or why not?

Density• The state or quality of being dense; compactness; closely set

or crowded condition.

P - Atmosphere–A mixture of gases that surrounds a

planet, such as Earth

P- Psychrometer

Tool used to measure moisture or relative humidity of the air (atmosphere).

P- Anemometer

A device for measuring wind speed.

P- Convection CurrentCircular movement caused by

differences in density of air depending on its temperature.

P - Upwelling

Process where water beneath the surface rises up to replace surface water pulled away by the wind.

P - Gyres

Ring-like system of ocean currentsrotating clockwise in the Northern

Hemisphere and counterclockwise in the Southern Hemisphere.

P- Gulf Stream

• The Sun heats up the water near the equator, and this water moves to the north.

Warm ocean current that flows North from the Gulf of Mexico, along the East coast of the United States.

P - Humidity

Amount of water vapor in the air.

P – Prevailing WindsWind that blows predominantly from a single general direction.

P- Air Mass

A large body of air that has

similar temperature and moisture

properties throughout.

P – Weather Front

the area wheretwo air masses with different temperatures and densities collide, but do not mix.

P – Jet Stream• Narrow band of air that moves at high

speeds caused by cold and warm air meeting.

P- Air PressureThe weight of the air pressing down on the Earth, the ocean, and on the air below causes air pressure.

P – Deep Water Current

Currents high in density because of the cold temperature that make up 90 percent of the ocean.

P – Surface CurrentCurrents low in density because of the warm temperature that make up 10percent of the ocean.

P – Coriolis effectThe rotation of the Earth

causes an interesting phenomena on free

moving objects on the Earth.

Objects in the Northern Hemisphere are deflected to the right, while objects

in the Southern Hemisphere are deflected

to the left.

P - Hurricane• A tropical storm with high winds. It

increases energy when coming in contact with warm water

S- Explain the difference between groups and periods on

the periodic table.

P PracticeGroup Discussion:When we were learning about the earth’s layers-

we learned about convection currents.

P PracticeThese convection currents were located in the mantle. They move the mantle around to keep it hot.

When it comes to convection currents in our atmosphere- the currents do the same thing!

Heat always rises- because it is less dense- so the warm air forces the cool air and this pattern continues over and over.

P PracticeThink about this:

Why is it usually cooler and windy at the beach than it is a few miles inland?

P Practice

3. The air above the ocean is cooler than the air above the land

1. The land warms the air above it and it rises.

4. Lastly, the cold air from above the ocean water moves in to take the place of the warm air that has risen.

2. The farther the air moves away from the “heat source”, the cooler it gets. So it then sinks back down (cold air sinks because it is more dense)

In your A section, write a descriptive paragraph of what you see.

Answer the following question as well:1. What is the purpose of the candle?

2. Why does the smoke rise through only one chimney?

3. What is the heat source for convection currents in our actual atmosphere?

P What is an Air Mass?Large pockets of moving air commonly form

that are separate from the surrounding atmosphere.

Two common properties of air masses are moisture content and temperature.

Types of air masses in North America:1. Maritime tropical 2. Continental tropical3. Maritime polar 4. Continental polar5. Continental Artic

Key Information***

Question to ask yourself did the air mass form over land or water?

Helpful Clues:Maritime: forms over the oceans-

wetContinental: forms over land- dry

A- Instructions for foldable• 1. Layer the 4 pieces of

printer paper so that an inch is showing.

• 2. Fold the other half of the paper over so you have 7 tabs.

• 3. Staple the very top of the foldable.

• 4. Label the foldable the following:

Blue=Maritime Tropical Orange= Continental Tropical Yellow=Continental Arctic

Green= Maritime Polar Red= Continental Polar

Maritime Tropical:

• Warm and humid, forms over a tropical ocean.

• Gulf of Mexico/Atlantic (will then go over SE US)

• Pacific (goes over West Coast)• Summer: showers/thunderstorms• Winter: heavy rain/snow

Maritime Polar

Cool, humid air masses form overNorth AtlanticNorth PacificTend to affect west coast more than

east coastBring rain, fog, and cooler temps.

Continental Tropical

Hot dry airForms over SW or Northern MexicoMove NE bringing hot dry weather

to Great Plains

Continental Polar

Bitter cold, dryForm over Central and Northern

Canada and Alaska (Arctic Circle)Winter: brings clear, cold, dry airSummer: brings milder temps, can

mix with warmer air and forms storms

Continental Artic

Extremely cold temperatures and very little moisture.

These usually originate north of the Arctic Circle and are mostly a winter air mass

How air masses move

1. Prevailing westerlies2. Jet streamsPush air masses west to east

Fronts: when two air masses meet the boundary is a front.

The less dense air mass floats on top of the other and storms tend to develop on frontal boundary.

C- Make sure you know the location of these regions and the type of weather conditions in

each.
