climate quiz Flashcards
what is climate
an average weather in a region over a few years
tundra
a treeless region, cold, it grows plants, northern hemisphere
ice cap
freezing, doesn’t grow plants, never above 0 degrees
ice cap
freezing, doesn’t grow plants, never above 0 degrees
factors
let vong latitude elevation topography vegetation ocean currents nearness to water global winds
latitude–how does it affect temp
closer to the equator is hotter
closer to n+s poles(90) is colder
bc-equator receive all year sun light –more sun = more heat
latitude–how does it affect precip.
0+60 n and s– air rises due to low pressure so their contracts and and squeezes out the moisture–lots of precip
30+90 n/s–due to high pressure the molecules are very closely packed and there is no room for water -no precip and dry air
elevation- how does it affect temp
lower elevation- hotter
higher-colder
higher up there is less pressure from other molecules pushing down so it has room to bounce around but lower elevation is being pushed down and has no room to move creating a hotter climate
elevation- how does it affect precipitation
higher - cause more precip bc more space for water molecules BUT water can also be too heavy to travel so some higher has less
nearness to water -how does it affect temp
water has a specific heat: the amt of energy required to change the temp of a substance
coastal towns have more moderate temp change range than inland towns
nearness to water - how does it affect precip
closer to water- more
further - less percip
ocean currents- how does it affect temp.
water coming from higher latitudes is colder and pushes colder air above it with it
water coming from lower = hotter and pushes hotter air w it
ocean currents - how does it affect precip
warm water = warmer air = holds more water and humidity
colder water= colder air- less water and humity
warmer air - expands creating space for water and more evap
colder air- contracts and lets its water go
topography - how does it affect temp
windward side - air cools as it rises
leeward side - air cools as it descends
^ both refer to elevation
topography - how does it affect precip
wside- lots of precip bc air needs to release moisture to get up the mt.’s peak
lside-no moisture left .. dry climate bc all was lost on w side
