When an ocean current passes by a location, it can affect the air temperature of that place.
True
100
Surface currents are caused by what?
What is the wind
100
When particles that make up something move fast the temperature will be...
hot or warm
100
The distance north or south of the equator is called?
What is latitude
200
What is the source of energy that heats the Earth's oceans?
What is the Sun
200
How does this image explain warmer climates at the equator compared to the poles?
Direct light at the equator make those climates warmer than the indirect light hitting the poles making them colder.
200
When an ocean current hits this, it will change direction.
what is a continent
200
Heat always flows from...
hot to cold
200
Air temperature can also change as you go up in elevation. Another word for elevation (that starts with the letter A) is...
Altitude
300
When the ocean is warmer than the air, heat flows in what direction?
From the ocean to the air
300
Why does Iowa have a colder climate than Texas?
Because Iowa is further from the equator (it has greater latitude)
300
When the air is warmer than the ocean, energy will from the ___________ to the __________________.
Energy will go from the air to the water.
300
What is the vocabulary word for the idea that some things heat up faster and cool faster than other things?
heat capacity
300
What would happen to ocean currents if energy from the sun did not reach the ocean?
No currents would flow
400
What is ocean water flowing in a continuous direction?
ocean current
400
What is the factor, from this image, that can affect the climate of a place?
ocean currents
400
The currents of the Earth are moved by energy from....?
the sun
400
Why is the air temperature at the equator warmer than the poles?
Because the equator gets more direct light than the poles.
400
3 things that can affect the temperature of the air in a place (and were studied in the is unit) are...
latitude, altitude, ocean currents, distance from the ocean
500
In the worlds oceans, cold water will start at the _______________ and warm water will start at the __________________. This is caused by __________________ heating from the sun.
Cold currents start at the POLES. Warm currents start at the EQUATOR. This is because of UNEQUAL or INDIRECT heating from the sun.
500
Why does a city in Japan have a warmer climate at the same latitude compared to a city in California?
Because Japan has a warm current passing by and California has a cold current passing by.
500
What is the name of either....
The current that brings cold polar water south along the coast of California...
OR
The current that brings warm water north towards Florida from the equator...
The California Current
OR
The Gulf Stream
500
Why would a city near the ocean have more stable temperatures throughout the year than a city inland?
Because the ocean keeps the climate of the city more stable than a city inland. The city near the coast gains and loses heat slower than the city inland.
500
How does an El Nino or La Nina year affect ocean currents?
These events change the direction or strength of ocean currents.
