the average weather conditions in an area; the weather conditions in an area over time
on the side away from, or sheltered from, the wind
the conditions in the atmosphere at a particular place and time
on the side toward, or exposed to, the wind
altitude, latitude, proximity to water, ocean currents
what controls the temperature of a region?
their latitude suggests that they should have harsher winters, but their proximity to large bodies of water and the warm North Atlantic Current create a warmer climate.
Why are the winters in Englnd and Ireland mild?
The prevailing winds that blow into this area come from Asia and are relatively dry
The Sahara is close to the ocean. Why is it a desert?
the side of a mountain that has a dry climate because precipitation falls mainly on the other side
urban heat island
the effect of the built environment of a city, including buildings, asphalt, and concrete, retaining heat and therefore maintaining a higher temperature than surrounding countryside; the city is a comparatively warm island amid cooler surrounds
by cold, dry winter air blowing over relatively warm water. The moisture rises, cools, condenses, and falls in the form of snow on the leeward side of the body of water. The extent of the effect is proportional to the size of the body of water.
how is lake-effect snow caused? and on what side of large bodies do you find it?
the higher the temperature the ______ the latitude
the lower the temperature the _______ the latitude
_________ can distribute heat and moisture to otherwise cold areas.
_______ (polar vs. tropical, maritime vs. continental) influence temperature and moisture
Mountains act as ______ to wind movements
Higher elevations tend to have _______ temperatures and more __________; especially snowfall
a graphic representation of at least two climatic factors, most often mean values for precipitation and temperature for an area

a region on earth characterized by similar climate
a sublayer of soil that remains frozen year-round
an area on a mountain above which no more trees can grow
Rain forests are found in which climatic zone?
South America is a relatively narrow continent, and no area is far enough from the ocean for this climate to exist.
Why is there no temperate continental climate in South America?
a visible mass of particles (droplets or frozen cyrstals) of condensed water vapor suspended in the atmosphere
it decreases with elevation
How does temperature change with elevation?
the process by which a gas, such as water vapor, changes to a liquid. This process is how clouds form.
A particle on which condensation will occur
in air, the presence of the most water vapor possible under existing pressure and temperature
the amount of water vapor in the air divided by the amount that would have to be present in the same air to form a cloud or condense on a surface
when the evaporation of water lowers the temperature of a liquid or object that it is in contact with
the temperature at which water vapor begins, or would begin, to condense
it means the air is saturated
What does it mean if air has a relative humidity of 100 percent?
temperature and atmospheric pressure
What determines the dew point?
near the equator
Where are tropical rain forests found?

the process in which the absorption of short wave radiation by the atmosphere heats up a planet
carbon dioxide, methane, water vapor
Name three greenhouse gases.
No, the heating of the atmosphere is needed for life to exist
Is the greenhouse effect bad?
by burning fossil fuels
How can the concentration of greenhouse gases be increased?
a gas in the atmosphere that traps heat near the surface
they contain trapped air bubbles from ancient atmospheres
What does an ice core tell about past temperatures and atmospheric conditions?
A. Ice cores have trapped air bubbles that contain air from ancient atmospheres.
They give clues to what types of plants and animals were able to survive in that climate.
Why are pollen and fossils useful in determining past climates?
the study of annual growth rings in trees to infer conditions in past environments
a dark, cool region on the sun.
no, it varies
the sun's energy output remain the same, yes or no?
The movement of a ______ from one latitude to another will change the climate on that continent. The movement of _______ also alters global atmospheric and ocean circulation.
__________ eject a tremendous amount of ash and dust into the atmosphere. This dust can stay in the upper atmosphere for years, blocking the sun's energy.
the movement of cold water and nutrients to the surface waters in the ocean.
La Niña has the opposite effects of El Niño
How is La Niña different from El Niño?
Trade winds shift to move toward the east, bringing warm waters to areas that generally have cold waters.
Why does El Niño occur?
The fish die or move from the lack of upwelling. Upwelling brings nutrients with it, so its absence would harm the bird population.
Why would sea birds die in an El Niño event?
Where does the sun hit directly on earth's surface
Is the North Pole surrounded by land or water?
