earth revolves around the sun tilted at what in relation to the sun

23.5 degree angle

Seasons affect?

conditions in the atmosphere & the Earth which create the weather

Because of the Earth's ______ and it's _____, different parts of the Earth receive direct rays of the sun for _____ hours of the day at certain ________ of the year

revolution, tilt, more, times

farthest north point latitude mark

Tropic of Cancer

farthest south point latitude mark

Tropic of Capricorn

Summer solsitce is the ______ day of the year?


another signal of season change are the?



storms that form over the warm, tropical ocean waters


weather conditions at a particular location

water vapor

determines the weather there will be precipitation

cloud covers

may hold water vapor

elevation above sea level

air becomes thinner and looses its ability to hold mositure

air movement

winds move the air and the solar energy and moisture that it holds, as a result, weather can change very rapidily


amount of water vapor in the air and the movement of the air

orographic precipitation

falls on the windward side of hills or mountains that block moist air and force it upward

frontal movement

causes most precipitation in the middle latitudes


boundary b/w air masses of different temperatures or density. the boundary b/w two air masses is pushed upward


as air masses warm and cool and move across the earth's surface


air flowing over an ocean with a temp of at least 80 degree F picks up huge amounts of moisture


water-laden winds flow into a low pressure core they tighten to form an eye usually about 10-20 miles across and has clear, calm skies


the clouds and winds stretch over a large area and can be as wide as 500 miles


upper air currents blowing from the east steer the hurricanes in westerly direction


as it hits land, it pounds the area with heavy winds and rains also causes storm surges across the region


twisters, powerful funnel shaped column of spiraling air


form quickly and sometimes w/o warning


born from strong thunderstorms; these are capable of alot of damage


winds swirl counter-clockwise around a low pressure center


winds can reach up to 300mph


generally have small diameters (300 feet), travel about a mile and last only a few minutes but the largest are the most powerful


A heavy snowstorm with strong winds more that 35mph


cause traffic hazards and endanger livestock


long period of time without rain or very minimal rainfall


lack of rain results in crop failures and drastically reduced levels in water storage facilities


early 1930s a drought hit the Great Plains in the US


dust storms damaged farms across a 150,000 square-mile region that became known as the dust bowl


water spreads over land


melting snow or rainwater fills streams or rivers until they reach the flood stage

flood plain

water that floods into the surrounding area

19th century fisherman along the _________ coast called the event __________

Peruvian, el Nino

El Nino

spanish name for the infant Jesus since the event

every _____ years, the water off the _________ become _______ than usual resulting in poor __________
