When one thing is increasing, another thing will also increase.
There are examples of positive feedback in many areas. A teacher praises a student for working well. This praise makes the student work harder. Positive feedback!
For example in our body if the concentration of glucose level increases then to maintain its concentration the production of insulin also increases as insulin can store it in the form of glycogen in liver and muscles.
In climate change, a warmer atmosphere can hold more moisture. More moisture makes the atmosphere warmer. The warmer atmosphere can hold more water... Etc. This loop is called positive feedback.
Another example is the albedo effect. This means that white icy areas, like sea ice, reflects the sun's heat. As that ice melts, the darker ocean below gets warmer. Because the ice is no longer there, global temperature rises.
Another example is global warming releasing Arctic methane. Scientists have found plumes of methane gas bubbling up from the ocean floor, as Methane hydrate (frozen water and methane combined) melts and releases the methane. The methane increases the warming, which means that more methane is released.

What this means is the result of an action then causes more of that action. Such as when you put a microphone next to a speaker, sounds made by the speaker are picked up by the microphone, amplified then broadcast again getting louder each time.

Positive feedback loops are usually part of a larger?
negative feedback loop
What happens during positive feedback loop?
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
How does a neuron create a positive feedback loop?
through what can be seen as the domino effect. when depolarization opens sodium ion channel and that results to the opening of more sodium ion channels. this creates a positive feedback loop.
Is the ADH feedback loop an example of positive or negative feedback explain?
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
Does deforestation create a positive or negative feedback loop effect?
negative. I'm not sure what a feedback loop effect is but i know that the more you chop, the more air we lose, the more animals lose their homes, the less air our cows have to make my burgers!
How is a positive feedback stopped?
The positive feedback loop is terminated by the end of childbirth...
What is a vicious cycle?
positive feedback loop
Positive feedback loops are usually part of a larger?
negative feedback loop
What happens during positive feedback loop?
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
What is sometimes called a''vicious cycle''?
positive feedback loop
What are four conditions in the cell that must be kept in the homeostatic balance?
- temperature - negative feedback loop - positive feedback loop - water balance
Ozone layer depletion is an example of what kind of feedback loop?
positive feedback loop because cause increases the effect. thank you very much!
What is an open loop in control systems?
A: By definition there is no control on a system in an open loop situation. simply . it has no feedback
What makes closed-loop op amp unstable?
A: It does not. The loop becomes unstable ONLY if there is positive feedback either voltage or phase. For a close loop to be stable negative feedback is required.
Is the war on drugs a positive feedback loop?
Yes. Have fun proving it.
How does a neuron create a positive feedback loop?
through what can be seen as the domino effect. when depolarization opens sodium ion channel and that results to the opening of more sodium ion channels. this creates a positive feedback loop.
What are the component of oscillator?
It can contain active and passive components with a positive feedback loop.
