Which example illustrates negative feedback in the interaction between Earth's atmosphere and geosphere?
Group of answer choices

Increased rainfall causes more trees to grow in a forest.

Earthquakes release heat from the geosphere, warming the atmosphere.

Volcanic activity releases carbon dioxide, making Earth warmer.

Volcanic dust and ash reflect sunlight, cooling the Earth after an eruption.

Question 21 pts
Which statement accurately describes the concept of feedback in a system?
Group of answer choices

Feedback is an external cause that does not influence the system's behavior.

Feedback is an unrelated change occurring in a system without cause.

Feedback is a process of the system's output influencing its future behavior or input.

Feedback is a constant input that keeps the system functioning steadily.

Flag question: Question 4
Question 41 pts
What distinguishes positive from negative feedback in a system?
Group of answer choices

Positive feedback decreases a system's output; negative feedback increases it.

Positive and negative feedback have no differences in a system.

Positive feedback amplifies changes; negative feedback opposes changes.

Positive feedback stabilizes a system; negative feedback destabilizes it.

Answered by GPT-5 mini AI
1) Volcanic dust and ash reflect sunlight, cooling the Earth after an eruption.
- Explanation: the cooling effect opposes warming, so it acts as negative feedback.

2) Feedback is a process of the system's output influencing its future behavior or input.
- Explanation: feedback means outputs loop back to affect the system.

3) equilibrium
- Explanation: equilibrium is the stable balance produced when competing factors cancel.

4) Positive feedback amplifies changes; negative feedback opposes changes.
- Explanation: positive drives system away from its current state; negative tends to restore it.

5) negative feedback
- Explanation: sweating cools the body and counteracts the initial increase in temperature.
