Question

Here are the questions:

1.) Thus, after just one cycle of this feedback loop, the change initially made on this system ultimately

A.) increases

B.) decreases

because atmospheric temperatures change further in the same direction.

2.) Which feedback loop best describes this example?

A.) positive feedback loop

B.) negative feedback loop

3.) The cascade of events resulting from the initial increase in atmospheric temperatures does not typically undergo just one cycle in nature. As this system continues to loop again into a second cycle and again into a third cycle and so forth, which of the following would you expect to occur?

A.) Atmospheric temperatures will continually rise.

B.) More and more ice will be produced.

C.) More and more heat will be absorbed by the ocean.

D.) All of the above

Human activities have increased atmospheric temperatures on earth. Ice melts from increased atmospheric temperatures. More heat results in even higher atmospheric temperatures. As reflective ice disappears, darker ocean water absorbs more heat.

Explanation / Answer

1.) Thus, after just one cycle of this feedback loop, the change initially made on this system ultimately increases because atmospheric temperature further change in the same direction.

2. negetive feedback loop best describe this example.

3. i expected to occur that amospheric temperatures will continually rise.

more and more heat will be absorbed by the ocean.
