water and carbon cycle relationships

Question 1

what is a positive feedback loop

Answer 1

the amplification of the original consequence

Question 2

what is a negative feedback loop

Answer 2

the nulification of an original consequence

Question 3

what do both cycles have in common

Answer 3

both have an effect on the climate, but both also are impacted by the climate

Question 4

what is the albedo effect

Answer 4

a positive feedback loop in which as the climate gets hotter, there are less relfective surfaces such as snow and ice so there is less deflection back into space, leading to further temp increases

Question 5

what is the permafrost effect

Answer 5

permafrost is an area of land which has been permamently frozen for 2 or more years. as temps rise this permafrost melts and releases co2 into the envrionment, further increasing temps.

Question 6

what is the cloud feedback

Answer 6

as temps rise, there is more evapotranspiration which leads to more water vapour in the atmosphere, this creates clouds and consequently these clouds can reflect more solar radiation.

Question 7

what is the methane hydrates effect

Answer 7

a change in the thermohaline circulation can release deep sea methane

Question 8

what is carbon fertilisation effect

Answer 8

as more co2 is in the atmosphere, there are faster rates of photosynthesis so plants grow quicker, this growth will lead to more co2 being taken in by vegetation. 25 % of co2 emissions are removed by plants

Question 9

how do the oceans and carbon link

Answer 9

ocean temps are rising as more co2 enters them

Question 10

links between carbon and rain

Answer 10

higher co2 levels have caused higher temps, which in turn has seen higher levels of precipitation in areas but droughts in others.
