Climate feedback loops

Front

What are the two types of feedback systems that help organisms maintain homeostasis?

Back

Positive and negative feedback systems.

Front

What is positive feedback?

Back

A process that amplifies changes; it moves a system away from its equilibrium state.

Front

What is negative feedback?

Back

A process that counteracts changes; it helps maintain stability and equilibrium in a system.

Front

What is homeostasis?

Back

The ability of an organism to maintain a stable internal environment despite external changes.

Front

What role do greenhouse gases play in climate change?

Back

They trap heat in the atmosphere, leading to global warming.

Front

Which gases are the most abundant in Earth's atmosphere?

Back

Nitrogen and oxygen.

Front

What is the primary source of anthropogenic greenhouse gas emissions?

Back

Burning fossil fuels for energy.

Front

How does deforestation contribute to climate change?

Back

It reduces the number of trees that can absorb CO2, increasing atmospheric carbon levels.

Front

What is a feedback loop in the context of climate systems?

Back

A process where the output of a system influences its own operation, either amplifying or dampening changes.

Front

What is an example of a positive feedback loop in climate change?

Back

Melting ice reduces the Earth's albedo, leading to more heat absorption and further ice melt.
