The Earth rotates from west to east and completes one rotation every 24 hrs.

What cause day and night?

Describes how the Earth revolves around the sun once in 365.25 days.

The revolution and the tilt of Earth gives us ________?

Because the Earth's tilt and revolves around the sun, the Earth's seasons are _______ in the Northern and Southern Hemisphere.

An imaginary line that runs through the Earth from pole to pole. It is currently titled at 23.5^o. Because of this tilt, not all Earth received the same amount of direct sunlight at the same time.

A period of equal daylight and equal darkness, it happens twice a year, around March 21st and September 23rd

a period of longest daylight and longest darkness; happens twice a year once around June 21st and December 22nd

located at 23.5^o North, it's the northernmost point on Earth that the sun's rays directly hit. This happens on the June solstice.

In the tropic of cancer, our Hemisphere experiences the ________ period of daylight during our summer and the Arctic Circle experiences almost continuous daylight. This continuous daylight is called the ________?

located at 23.5^o South, it's the southernmost point on Earth that the sun's rays directly hit.

This happens on the December solstice, Our Hemisphere experiences the ________ period of daylight during our winter, and the Arctic Circle experiences almost continuous darkness.

What latitude is the Arctic Circle?

What latitude is the North Pole?

What latitude is the Antarctic Circle?

What latitude is the South Pole?

________ is between 23.5^o North and 23.5^o South, this includes the Equator, Tropic of Cancer, and the Tropic of Capricorn. They receive direct rays from the sun year round, and these latitudes have warm to hot climates.

_________ is between 23.5^o North and 66.5^o North and 23.5^o South and 66.5^o South; range from fairly hot to fairly cold, with dramatic seasonal changes

_______ is between 66.5^o North and 90^o North and 66.5^o South and 90^o South; the Arctic circle has a fairly cold climate for most of the year; both area have about 6 months of daylight and 6 months of night; home of the Midnight sun and Aurora Borealis

the height of an areas above sealevel, no matter where you are on Earth, the higher the elevation the cooler it is.

The temperature drops _______ for every 1000 feet in elevation you go up

(the atmosphere thins and can't hold heat as well)

What three continents lie partially in the Arctic Circle?

What continent lies solely in a high latitude?

What three continents are crossed by the Equator?

Explain the difference between climate and weather?

atmospheric conditions at particular location and time; a short term aspect of climate; reported as a forecast; including natural disasters

weather conditions at once location over a long period of time, reported as average; typically includes data from the past 30 year

How would you describe South Louisiana's climate?

Both climate and weather are influenced by

How does weather affect our lives? How does climate affect our lives?

Global climatic changes may be natural or human-made.

A process that occurs when gasses in Earth's atmosphere trap the Sun's heat; this process makes Earth much warmer than it would be without an atmosphere

Greenhouse effect makes Earth a comfortable place to live; its Earth's way of regulating its temperature

Makes Earth a comfortable place to live; It's Earth's way of regulating its temperature

the overheating of Earth due to too many greenhouse gasses in the atmosphere,

Why is greenhouse effect necessary for life?

How does the greenhouse effect cause global warming?

Beside climate change, why are greenhouse gasses harmful?

air moving across Earth's surface; created by the sun heating the Earth's surface

global winds that blow a fairly consistent pattern

prevailing winds mainly in the low latitudes, blowing from about 30^o N latitudes and 30^o S latitude; blow in a constant east to west direction, angled towards the equator

Area around 30^o N and 30^o S with little or no wind

prevailing winds located between 30^o N and 60^o N latitude and between 30^o S and 60^o S latitude; blow in a West to eat direction, angled toward the Arctic and Antarctic Circle

_________ lie between 60^o N latitude and the North Pole and between 60^o S and the South Pole; blow in a general east to west direction and push cold polar air towards the middle latitudes

Because the Earth rotates to the east, the global winds are displaced clockwise in the Northern Hemisphere and counter clockwise in the Southern Hemisphere. This is know as the ________?

What is the difference between doldrums and horse latitudes?

How did horse latitudes earn their name?

Why do storms spin in different directions depending on their location, and why do they spin in the first place?

cold and warm streams of water

______ currents influence by the Earth's rotation, changes in air pressure, and differences in water temperature; affect climate near coastal areas

______ refers to the _______ sea-surface temperatures that periodically develop across the east-central equatorial Pacific

_______ refers to the periodic _________ of sea-surface temperatures across the east-central equatorial Pacific?

How does El Nino impact Louisiana weather?

How does La Nina impact Louisiana's weather?

Which occurs more frequently, La Nina or El Nino?

_______ side of mountains that face the wind; prevailing winds bring moist air that condenses as it cool, and precipitation falls

_______ side of mountains that are on the opposite side of the winds; the hot dry air produces little precipitation

A dry area on the leeward side of a mountain area; mountains block the passage of rain producing weather systems an cast a shadow of dryness on them

The leeward side of the mountain in in the

1. This side of the mountain is dry and desert like because of the rain shadow effect.

What do geographers use to determine climate?

Define Conifer?

Define Evergreen.

Define Deciduous.

Define Mediterranean Scrub (chaparral)

Define Permafrost.

What is a polar desert?

How is a desert different from a steppe?

How are highland climates and high latitudes climates similar?

What's the difference between an evergreen tree and a deciduous tree?
