Circular movement of water within an ocean basin
Gyre
Gulf Stream
Salinity
Rip Current
The effect of Earth's rotation on the direction of winds and currents.
Gyre
Longshore Current
Coriolis Effect
When a surface current collides with land
Caused primarily by the wind and moves in a circular pattern due to the coriolis effect. Mixed by winds, waves, and currents.
warm surrent
surface current
Antarctic circumpolar current
when a surface current collides with land
Begins at the equator and results from higher temperatures at that latitude. Gulf stream is an example of this.
Coriolis effect in the Northern Hemisphere
Coriolis effect in the Southern Hemisphere
current
warm current
Begins at the polar caps and are the result of lower temperatures at that latitude. California Current is an example.
cold current
warm current
salinity

What is the name of large masses of moving air caused by uneven heating of the Earth's surface by the sun?
Land breeze
Global wind
Jet Stream
Coriolis Effect
What determines the three main types of climate zones?
Latitude
Longitude
ocean currents
wind patterns
Which of these are set in motion by the uneven heating of Earth's surface?
solar radiation
ocean waves
convection currents
surface water runoff
Because convection cells are in place in the atmosphere, and Earth is spinning on its axis, global winds appear to curve. This is known as the
Greenhouse effect
gravitational pull
Global Winds
Coriolis effect
Surface currents are a result of
Global wind patterns
density
Earth's rotation
all of them
Deep ocean currents are a result of
Global wind patterns
Earth's rotation
density
all of them
The Coriolis effect is caused by
Earth revolving around the sun
Earth rotating on its axis
The tides
Gravity

All of the following are true about the Greenhouse effect EXCEPT:
They block heat from escaping into space
They keep Earth warm
Nitrogen, Carbon, and Fluorine are the most important ones
They make life on Earth possible
Methane is a Greenhouse Gas. Where does most of the methane come from?
burning fossil fuels
agriculture and livestock
from upwelling
trees release it from their leaves during photosynthesis
