Question

The following feedback loop exists:

- If air temperature goes up, CO2 storage in the soil goes down.

- If CO2 storage in the soil goes down, atmopsheric CO2 goes up.

- If atmospheric CO2 goes up, air temperature goes up.

Question #1: This is an example of:

A positive feedback loop where an equilibrium point is not reached.

A negative feedback loop where an equilibrium point is not reached.

A positive feedback loop where an equilibrium point is reached.

A negative feedback loop where an equilibrium point is reached.

Regarding the feedback loop described in the previous question, the second statement is:

An example of a negative coupling

An example of a positive coupling

An example of a negative feedback

An example of a positive feedback

Tropical rain forests are most commonly found on Earth where:

The Hadley cells uplift at the ITCZ

The Hadley cells have downward circulation (at about 30° latitude) and behind (downwind from) mountain ranges.

Along the polar front

In regions dominated by high pressure systems

A positive feedback loop where an equilibrium point is not reached.

A negative feedback loop where an equilibrium point is not reached.

A positive feedback loop where an equilibrium point is reached.

A negative feedback loop where an equilibrium point is reached.

1. This is an example of:

A positive feedback loop where equilibrium point is not reached.

2. The second statement is positive feedback

3. The Hadley cells uplift at the ITCZ. ITCZ is the Inter-Tropical Convergence Zone. So, tropical forests are found here.
