Which of the following scenarios are examples of positive-feedback mechanisms? check all that are correct.
deforestation near the sahara desert causes the soil to be exposed. exposed soil evaporates moisture more readily. insufficient moisture leads to the death of trees.
a warmer atmosphere causes more evaporation. more water vapor in the atmosphere leads to more cloud cover, which reflects more incoming solar radiation back to space and cools the surface.
a warmer atmosphere causes more evaporation. water vapor is a greenhouse gas, so this increases the temperature.
earth warms and radiation cools earth, much like a warm cup of coffee cools down if you let it sit on a table.
warmer temperatures cause snow to melt. this makes the ground darker, allowing more solar radiation to be absorbed. the warmer ground warms the atmosphere.
