Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that accumulates and stores carbon-containing chemical compounds for an indefinite period, helping to reduce the amount of carbon dioxide in the atmosphere.

Front

What is a carbon source?

Back

A carbon source is any process or activity that releases carbon dioxide into the atmosphere, contributing to the greenhouse effect and climate change.

Front

What happens to the Earth's average temperature when greenhouse gases are released?

Back

The average temperature of the Earth goes up.

Front

What is albedo?

Back

Albedo is the measure of the reflectivity of a surface, expressed as a fraction or percentage. It indicates how much sunlight is reflected back into space.

Front

How does melting ice caps affect the Earth's albedo?

Back

Melting ice caps lower the Earth's albedo, meaning less sunlight is reflected and more is absorbed, contributing to further warming.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions in a specific place at a specific time, while climate is the long-term average of weather patterns over a significant period.

Front

Why is a high albedo roof beneficial for keeping a house cool?

Back

A high albedo roof reflects more sunlight, reducing heat absorption and keeping the house cooler.

Front

What role do oceans play in carbon cycling?

Back

Oceans act as a carbon sink, absorbing carbon dioxide from the atmosphere and helping to regulate global climate.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping into space and thus warming the planet.

Front

What are some human activities that increase greenhouse gas emissions?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes increase greenhouse gas emissions.
