green house gases

A

CO2
methane :CH4
H20 vapor

5
Q

allow visible light to pass thru which is absorbed by earth and released as heat, but hat cannot pass thru gases and is stuck on earth building up

A

green house gases

6

put carbon into atm

A

sources

7
Q

remove carbon from atm

A

sinks

8
Q

5 sources

A

1) weathering of limestone
2) volcanic activity
3) burning and decay of biomass
4) respiration
5) burning of fossil fuel

9
Q

5 sinks

A

1) weathering of granite
2) photosynthesis
3) burial of biomass
4) deposition of carbonate sediments
5) CO2 dissolves in sea water

10
Q

:more efficient green house gas than CO2

:created by breakdown of organic material

A

methane

11
Q

:how eliptical an orbit is

:the closer to the sun, the more solar energy received

A

eccentricity

12
Q

:tilt of earth’s axis
:determines seasons
:if zero–> no seasons

A

obliquity

13
Q

:wobble of earth: like a spinning top
:caused by gravitational effects of sun and moon
:changes direction of tilt of Earth’s axis

A

Precision

14
Q

important for life in ocean and is responsible for protein which is used by plants and animals

A

nitrogen

15
Q

chemical process that creates ammonium nitrate

A

Haber-Bosch Process

23
Q

relationship of solubility of gases and temp

A

as temp rises, solubility decreases

24

a species gets divided into 2 species after being separated

A

allopatric speciation

26

A

adaptation

27
Q

:determines if a mutation is neutral, positive, or negative

:isnt random

A

natural selection

28
Q

species develop similar characteristics to exploit similar resources

A

convergent evolution

29

\:Smith --> Species
33
Q

what has driven evolution

A

steady change (biology) and punctuated equilibrium

34
Q

:accumulation of genetic change creates new species over long periods of time

A

biology–> steady change

35
