Which of the following is the best example of a positive feedback effect?
A)Melting ice exposes the dark surface of the ocean, which reflects less of the sun's energy than ice. This heats the water and in turn, melts more ice.
B)Melting ice exposes the dark surface of the ocean, which reflects more of the sun's energy than ice. This heats the water and in turn, melts more ice.
C)Melting ice allows ocean levels to rise and reduce the surface area of the remaining ice, slowing its melting rate.
D)Aerosols block the sun's radiation, slowing the melting of ice.
E)Aerosols cause air pollution, which increases local drought conditions.

Melting ice exposes the dark surface of the ocean, which absorbs more of the sun's energy than ice, leading to further warming and more ice melting. This is a classic example of a positive feedback loop where an initial change is amplified by the effects it causes.
