A feedback loop is a loop where an output can influence change in an input of the process

Positive feedback loops enhance or amplify a process such as an ape eating food that it likes so it will eat more. Negative feedback loops lessen a process so if an animal is hurt by touching a cactus, it will not touch the cactus again

The higher the albedo, the more reflection occurs, so the rock will reflect more radiation since 0.30 is greater than 0.20

The more water vapor in the atmosphere amplifies the greenhouse effect, which will allow for more radiation to be absorbed, which will be redirected to evaporate more water into water vapor

a) If there were more clouds and temperatures lowered then the amount of evaporation would lower since the temperatures are lower and less energy is transferred to these water molecules

b) This is a negative feedback loop as the increased water vapor presence results in the water vapor presence and evaporation rate lowering

a) If there were more clouds and temperatures lowered then the amount of evaporation would lower since the temperatures are lower and less energy is transferred to these water molecules

A planet’s albedo is its rate of radiation reflection compared to how much radiation it receives. The higher the albedo value the more reflection there is

b) positive since if the ice increases reflection, less energy is absorbed that would melt the ice

A planet’s albedo is its rate of radiation reflection compared to how much radiation it receives. The higher the albedo value the more reflection there is

a) the increased amount of ice increased albedo and further decreased surface temperature

b) Less energy was absorbed during the ice age than is absorbed today. This would have prevented the melting of the ice

As ice increases, albedo increases, so more ice is formed since little will melt with the decreasing temperatures that are caused by the increasing albedo

a) the increased amount of ice increased albedo and further decreased surface temperature
