Q
climate feedback
A
can be positive or negative, is a secondary change that occurs in the climate system due to a primary change
3
Q
positive feedback
A
a feedback that becomes stronger as time goes on
ex: more water vapour leads to more heat trap and more evaporation and leading to more water vapour
4
Q
negative feedback
A
a feedback that becomes lesser and time goes on
ex: more water vapour leads to more cloud cover which allows less heat in and so less evaporation means less cloud cover
5
Q
insolation
A
the amount of heat the Earth receives from the sun
