global warming

a continental polar air mass moves into the territory occupied a continental tropical air mass. what is most likely to happen?

a cold front forms at the boundaries between the two air masses

what is ozone

a gas that resides in the stratosphere, a gas consisting of molecules containing three oxygen atoms, and a gas that blocks ultraviolet radiation from reaching earth

when water changes from a liquid to a vapor it

absorbs heat from the environment

near a high-pressure weather system (also called an anticyclone), clouds are unlikely to form. why is this?

air flows downward and outward from a high

what is air pressure greatest at sea level?

air pressure depends on the weight of overlying air molecules

what is the gulf stream

an ocean current that moves warm water from the equator to the coast of northern Europe, a surface current, and the source of warm winds that blow from the ocean over the lands of Great Britain and Norway

global winds blow a maritime tropical (mt) air mass inland. over time, this air mass is likely to

become a continental tropic air mass

how is the atmosphere like a florists greenhouse

both trap long-wave electromagnetic radiation

the ocean current called the gulf stream

carries heat from the gulf of mexico to the north american coast and northern European

suppose that you saw clouds that were high in the sky and looked like wispy strands of tattered cloth. an hour later, it started to rain. the clouds you saw were

cirrus clouds

how are weather and climate related

climate is the average whether over a period of many years

the weather forecast says that a warm front is moving into town. while the front is in town, what kind of whether is likely?

cloudy with precipitation

the change of water vapor to liquid is called

condensation

as an air parcel rises, it

expands and cools

what slows the escape of long-wave radiation from the earths surface

greenhouse gasses

if the concentration of carbon dioxide in the atmosphere increases, earths average global temperature will

increase

an air mass that contains warm, moist air is a

maritime tropical air mass

wind is due to

pressure differences in the atmosphere

cyclones are areas of low pressure. they are associated with

rough weather

what factors determine earths average global temperature

solar radiation and greenhouse gas concentration

why are you more likely to get sunburned if you visit a low altitude location compared to a high-altitude location

solar rats strike low altitude locations most directly

the elements of weather include

temperature and precipitation

why does air flow into the center of a cyclone

the center of a cyclone is a region of low air pressure

temperatures in earths atmospheric layers vary in zig-zag pattern with altitude principally

the chemical composition of the atmosphere varies

why is water vapor not implicated in climate change as methane and carbon dioxide are

the concentration of water vapor in the atmosphere has remained relatively constant despite changes in human activity

on what day of the year does the north pole tilt most directly toward the sun

the summer solstice

almost all energy on earth comes directly or indirectly from

the sun

the seasons are primarily due to

the tilt of the earths axis

the troposphere is the atmospheric layer where

weather occurs

air pressure is due to the

weight of the overlying air

the Coriolis effect turns

wind and ocean surface currents

earths surface receives more solar radiation near the equator than at the poles. this uneven heating of earths surface produces

winds
