Understanding Climate Feedback Loops

What is a climate feedback loop?

• A process that amplifies or diminishes the effects of climate changes.

• A method to measure temperature changes over time.

• A cycle of weather patterns repeating annually.

• A system for predicting future climate conditions.

How does a negative feedback loop affect Earth's climate?

• It amplifies the initial change.

• It stabilizes the climate by counteracting changes.

• It accelerates global warming.

• It has no effect on climate change.

What is the primary difference between positive and negative feedback loops?

• Positive feedback loops decrease temperature, while negative feedback loops increase it.

• Positive feedback loops amplify changes, while negative feedback loops counteract changes.

• Positive feedback loops are beneficial, while negative feedback loops are harmful.

• Positive feedback loops occur naturally, while negative feedback loops are man-made.

What happens to Earth's climate when a positive feedback loop is triggered?

• The climate becomes more stable.

• The initial change is amplified, leading to more extreme conditions.

• The climate returns to its original state.

• The effects of climate change are reversed.

What is the effect of increased water vapor in the atmosphere as a feedback mechanism?

• It decreases the greenhouse effect.

• It has no impact on climate.

• It enhances the greenhouse effect, leading to warming.

• It cools the Earth's surface.
