25
what direction does a high pressure system flow
clockwise
26
what does a high pressure system cause
air sinks. clear skies
27
what are the 4 weather fronts
cold front, warm front, stationary front, and occluded front
28
what causes cold front
when cold causes warm air to rise
29
what is a cold front represented by on the news
they are represented by blue triangles
30
how are warm fronts created
warm air rises gently above cold air
31
what are the warm fronts represented by in the news
red cemi-circles
32
how do stationary fronts form
cold and warm air masses meeting together and neither front advances
33
how are stationary fronts represented by in the news
alternating cemi-circles and triangles
34
how are occluded fronts created
a fast moving cold front overtakes a warm front
35
how are occluded fronts represented in the news
purple alternating cemi-circles
36
what is a climate that is strongly affected by an ocean
Maritime climate
37
what is a climate that is not directly affected by an ocean
continental climate
38
what blows from over the water toward land in the afternoon, when the land is warmer than the water
sea breeze
39
what is climate
its long term average of weather conditions
40
what is weather
is the day to day outside conditions
41
what are the five spheres
lithosphere,hydrosphere,cryosphere,biosphere,and atmosphere
42
what is the atmosphere
the air around us
43
what is the biosphere
is everything organic
44
what is the hydrosphere
is liquid water
45
what is the cryosphere
is frozen water in snow, ice, and glaciers
46
what is the lithosphere
earths outermost layer
47
what is the primary factor that influences climate
latitude
48
where is the solar radiation most intense on earth
the equator
49
at what degrees do the sun rays hit earth's tropic zone
90 degrees
50
what degrees does the suns rays hit the temperate zone
45 degrees
51
what degrees does the suns rays hit hit the polar zone
30 degrees
52
what zone are we located in
temperate zone
53
what factors determine climate
precipitation, mountains, bodies of water
54
what is the windward side like on the mountain range
air is cool and wet and lots of vegetation
55
what is it like on the leeward side of a mountain range
its warm and dry with little to no vegetation
56
which climate zone and what type of vegetation does colorado have
warm and semi-arid
57
an increase in the average temperatures of Earth's near-surface air and ocean is called what
global warming
58
what is the warming of the Pacific Ocean off the coast of western South Africa that occurs every 3 to 10 years
el nino
59
the opposite of el nino is what, which occurs when trade winds in the Pacific are unusually strong and surface water is colder than normal
la nina
60
what are two climate changes the earth undergoes
seasonal and long-term
61
how do seasonal changes to happen on earth
it revolving around the sun
62
which hemisphere is in summer
the hemisphere that is tilted toward the sun
63
what is the period of time that the earth was covered in ice
the ice age
64
how long ago did the world reach its current pattern
about 3000 years ago
65
what are some factors that cause climate change
earths axis, the shape of the orbit, timing of the season
66
what causes an increase in climate
energy consumption, deforestation, and industrial and agricultural practice
67
what is deforestation
is when a large area of trees get cut or burned
68
how does deforestation cause climate to increase
because trees absorb co2 and if fewer trees are around the bigger the amount of co32 is in the atmosphere
69
what are the two ways the carbon cycle is affected
by deforestation and loss of vegetation
