water atmosphere

Question 1

how much of atmosphere is oxygen and nitrogen

Answer 1

oxygen: 21%
nitrogen: 78%

Question 2

photosynthesis

Answer 2

co2 + h2o +sunlight = glucose and o2

Question 3

troposphere

Answer 3

weather occurs. temperature decreases with altitude. the higher you are, the colder it is. churning

Question 4

stratosphere

Answer 4

temperature increases with altitude. no “churning”

Question 5

how much solar radiation does earth’s surface absorb

Answer 5

51% after filtered absorbed and reflected

Question 6

winds

Answer 6

average temperature higher in equatorial region. equatorial region recieves more direct solar radiation

Question 7

coriolis effect

Answer 7

caused by unattached atmosphere over rotating earth

Question 8

prevailing winds

Answer 8

the direction wind blows MOST of the time. winds from the west

Question 9

local wind patterns

Answer 9

heat capacity of land is low, heat capacity of water is large.

day: land warmer
night: land cooler

Question 10

cloud forming processes

Answer 10

convection results from differences in temperature.
warm= less dense
cold= denser

Question 11

weather fronts

Answer 11

front: boundary between 2 diff air masses
cold front: cold air mass moving in warmer area resulting in towering thunderclouds

Question 12

what is solar radiation

Answer 12

whatever happens with water and wind

Question 13

how much of earth’s saltwater (marine)

Answer 13

97% of the ocean

Question 14

freshwater how much of it on earth?

Answer 14

less than 3% of earth.
glaciers over 75%
lakes and rivers less than 1%

Question 15

hydrologic cycle

Answer 15

evaporation and condensation.
more water evaporated from ocean then preciptation
COLD WATER SINKS, WARM RISES

Answer 16

gulf stream and prevailing westerlies

Question 17

milankovitch cycle

Answer 17

earth spins like a tabletop once every 26,000 years.
ice age tied into orbital effects

Question 18

changes of earth

Answer 18

earth and sun closed system. no net gain of loss matter

Question 19

ozone hole

Answer 19

absorb harmful ultraviolet radiation. surrounds earth

Question 20

chlorofluorocarbons (CFC)

Answer 20

partial destruction of ozone layer. increase exposure to ultraviolet radiation causing skin cancer

Question 21

acid rain

Answer 21

burn of fossil fuels. nitrogen oxide, sulfur compounds, hydrocarbon, water= sulfuric acid

Question 22

greenhouse effect

Answer 22

trap heat inside, gases in upper atmosphere trap heat escaping earth
