Quick questions on Climate feedbacks and tipping points: WACE Year 12 Earth and Environmental Science
3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What are positive feedbacks?Show answer
Positive feedbacks reinforce the initial change, making warming worse.
What are negative feedbacks?Show answer
Negative feedbacks oppose the change, helping stabilise climate, though they are generally weaker than the positive ones.
What are tipping points?Show answer
A tipping point is a threshold where a small additional change pushes part of the climate system into a new state that is hard to reverse.
