Front

What is albedo?

Back

Albedo is a measure of the reflectivity of a surface, expressed as a fraction of the incident light that is reflected. It ranges from 0 (no reflection) to 1 (total reflection).

Front

Which surface has an albedo score of 0?

Back

A pitch black rooftop has an albedo score of 0, meaning it reflects no light.

Front

Which surface is expected to have the lowest albedo?

Back

Dark soil is expected to have the lowest albedo among the given options.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns of temperature, humidity, wind, etc., over extended periods.

Front

What process removes carbon dioxide from the atmosphere?

Back

Tree farms help remove carbon dioxide from the atmosphere through photosynthesis.

Front

What is a positive feedback loop in climate science?

Back

A positive feedback loop amplifies changes; for example, melting ice reduces albedo, leading to more heat absorption and further ice melting.

Front

What is the role of forests in carbon cycling?

Back

Forests act as carbon sinks, absorbing carbon dioxide during photosynthesis and storing carbon in biomass.

Front

How does the albedo effect influence global temperatures?

Back

Surfaces with high albedo reflect more sunlight, helping to cool the Earth, while low albedo surfaces absorb more heat, contributing to warming.

Front

What is the significance of ice caps in climate regulation?

Back

Ice caps reflect sunlight due to their high albedo, helping to regulate global temperatures.

Front

What is deforestation and its impact on climate?

Back

Deforestation is the clearing of forests, which increases carbon dioxide levels in the atmosphere and reduces the planet's ability to absorb CO2.
