Question

1. glaciers are white and reflect solar radiation back into the atmosphere which keeps the earth cool. when a glacier melts, the land or sea that is left behind absorbs more solar energy as it is darker in color. this leads to warmer temperatures which then leads to more glacier melting and warmer temperatures.

positive feedback loop

negative feedback loop

neutral feedback loop

a positive and negative feedback loop

Explanation:

The scenario describes a cycle where glacier melting leads to warmer temperatures, which in turn causes more glacier melting—amplifying the initial change. This is the definition of a positive feedback loop, where a change triggers processes that increase the magnitude of the original change.

Answer:

Positive feedback loop
