Feedback Loops

Front

What is a feedback loop?

Back

A feedback loop is a process in which the output of a system influences its own input, creating a cycle of cause and effect.

Front

What is a positive feedback loop?

Back

A positive feedback loop is a process where an initial change leads to further changes in the same direction, amplifying the effect.

Front

What is a negative feedback loop?

Back

A negative feedback loop is a process where an initial change leads to a response that counteracts the change, stabilizing the system.

Front

How does increased evaporation affect cloud formation?

Back

Increased evaporation leads to more clouds, which can increase albedo and reflect sunlight away from the Earth.

Front

What happens to temperature in a negative feedback loop?

Back

In a negative feedback loop, temperature tends to stabilize as the system works to counteract changes.

Front

In a positive feedback loop, what happens to the initial action?

Back

In a positive feedback loop, the initial action is amplified, leading to greater effects.

Front

What is an example of a negative feedback loop in nature?

Back

An example is the regulation of body temperature: when the body overheats, mechanisms like sweating are activated to cool it down.

Front

What is an example of a positive feedback loop in social media?

Back

An example is a viral post: as more people engage with it, the algorithm promotes it to even more users.

Front

What role does albedo play in climate feedback loops?

Back

Albedo refers to the reflectivity of a surface; higher albedo can lead to cooling effects in negative feedback loops.

Front

How do feedback loops relate to equilibrium?

Back

Negative feedback loops help maintain equilibrium by counteracting changes, while positive feedback loops can disrupt it.
