latitude

latitude

What factor affects the average temperature of a location the greatest

microclimate

The fact that a large city if often a few degrees warmer than the surrounding region is an example of a

climatologist

a specialist that could probably provide the most trustworthy data research study on climate change

climate

term that describes the average weather conditions in an area over a period of many years

average precipitation and average temperature

two key weather factors that allow scientists to describe and map different climate zones

nearly vertical

sun heats the earth's surface most effectively when the rays are more ________ to the earth's surface

The first view is anti-environmentalism . They think that there is no need to worry about using the earth and its resources wisely, since God is going to burn the earth up and create a new one. They aren't concerned about conservation. Then, there is radical environmentalism. They think that people are nature's biggest problem, and that "Mother Earth" must be protected at all costs, because we came from the earth through evolution. They believe that technology is bad, man's works are evil, and that nature is good.

two improper extremes of environmentalism

toward the sun

during summertime in the Northern Hemisphere the North Pole is tilted _______

summer

the day when the sun's noon rays are vertical above the Tropic of Capricorn would be called the ______ solstice in the Southern Hemisphere

winter

when it is summer in the Southern Hemisphere it is ________ in the Northern

tropical

there are two temperate zones but only one _______ zone

66 1/2 N & S latitude

boundaries of the Arctic and Antarctic circles are located at what degrees latitude

Air temperature in the troposphere usually drops with altitude (lapse rate). This means that places near sea level at a given latitude are generally warmer, while places at a higher elevation are generally cooler. Temperature lowers as you go higher.

Explain how lapse rate of the troposphere relates to temperatures at different levels of a mountain

monsoon

________ winds are seasonal winds that bring six months of rainy weather in southeast Asia

no

is the canopy theory accepted by most creationary scientists today

define a climatologist

scientists who study Earth's climate and the factors that seem to affect it. they study a branch of atmospheric science. They study tree rings, take ice cores, study hurricanes, and create and analyze climate models. They forecast not on the weather, but on trends in the weather.

temperate marine/ tropical rainy

in what climate would a citrus grove grow the best

dry

Australian Outback

tropical rainy

African savanna

polar

Siberian tundra

temperate continental

Forests of US Great Lakes region

highlands

Slopes of Mt. Kilimanjaro

temperate marine

Mediterranean coast of Europe

less than two centuries

scientists have been gathering information related to natural processes for ______

greenhouse hypothesis

name of hypothesis where man- made carbon dioxide is causing earth's rising temperature

icebergs

large chunks of ice that break off continental glaciers

sunspot activity

if this increases it may also cause global warming

estivation

hibernation but in the summer

lower earth's temperature

what effect major volcanic eruptions and dust storms would have

increase

the direction of the 0.5- 0.8 degree C. temp. change in last 50 years

ENSO

during this period South America, Mexico, and the SW United States receive flooding rains

ice cores

studies to determine how atmospheric carbon dioxide levels change over decades

precipitation

called Earth's thermostat because it helps regulate temps on Earth's surface

Antarctica & Greenland

where you can find continental glaciers today

one

number of major ice ages that occurred according to young-earth view
