Multiple Choice

Which form of energy heats the Earth?

• Mechanical

• Radiant

• Electrical

• Chemical

Open Ended

In your own words, describe the Coriolis Effect. Your response must contain the words: rotation, curve, and wind.

Poll

Radiant/ solar energy spreads across ____, thus impacting climates all ove

• latitudes (horizontally)

• longitudes (vertically)

• the Equator (centrally)

Multiple Choice

Uneven heating impacts:

• Ocean Currents

• Global Climates & Local Weather

• The Hydrologic Cycle

• Wind & Air Masses

• All of the above

​Factors that Effect Global Climates

​Climate is the average weather conditions in a region over a certain period of time. Factors --> LOWERN

L- Latitudes

O- Oce​an currents

W- Wind & air masses

E- Elevation

R- Relief

N- Nearness to water​

​

Latitudes:

As a result of the sun's rays s​spreading across the latitudes:

The area closest to the _____ has ___ temps and moist air.

The area closest to the _____ have ___ temps and dryer

​Ocean Currents- Global Heat Distribution

​OCs determine the climate in a region (i.e. cold currents keep coastal air temps cold, creating colder climate conditions and vice versa). **Difference surfaces absorb

​

The California Current is the cold West Coast current; the Gulf Stream Current is the warm East Coast current.

​

The Coriolis Effect explains the direction OCs rotate in.

​

Density is determined by salinity and & temperature of the current --> heat rises, cold sinks.

​

​

​Ocean Currents- Global Heat Distribution

​Surface currents are controlled by wind

​

Deep currents are controlled by nearness to/ away from Equator (the latitudes)

​

An OC's density is determined by salinity & temperature --> warmer, less saltier water will rise while the colder, saltier water sinks.​

​

​Different surfaces (i.e. soil, sea ice, ocean, sun) absorb sunlight differently (more/ less sun will be absorbed).

How do ocean currents impact a region's climate?

Multiple Choice

How will a cold ocean current impact a region's climate?

• It would make an area that would normally have a warm climate cooler.

• It would have no impact on the region.

Multiple Choice

How will a cold ocean current impact a region's climate?

• It would make an area that would normally have a warm climate cooler.

• It would have no impact on the region.

Fill in the Blank

Which has more salinity/ higher salt concentratIon, freshwater or saltwater? Which is more dense, freshwater or saltwater? (Sentence Starter: ______ has more salinity and is ______ dense than ______. )

Multiple Choice

What determines how/ if surface currents will mix with deep currents?

• Differences in the density of the currents

• Differences in the volume of the currents

• Differences in the rotation of the currents

• They will not mix

• They will always mix

​Wind & Air Masses

​As convection currents cycle through warm and cool air, this produces wind/ air, thus air pressure.

​

Wind/ air moves from areas of higher pressure to areas of lower pressure, distributing heat and moisture around the world.

​

A jet stream separates colder northern air from warmer southern air, which impacts migration patterns of birds. ​

How do you think the jet stream impacts the migration pattern of birds? (Sentence starter: Weather _____ of the jet stream means ______ temperatures, meaning birds will migrate to areas __________ the jet stream.)

Multiple Choice

A large volume of air with the same temperature and moisture content is defined as the________.

• air presssure

• air mass

• air volume

• air density

Multiple Choice

The type of air mass is determined by:

• Direction of wind & ocean currents

• Area of origin & moisture

Multiple Choice

A boundary that forms between two air masses is called a

• deep current

• front

• aquifer

• cloud
