Understanding Albedo and Solar Energy

Front

What is albedo?

Back

Albedo is a measure of the amount of solar energy reflected by a surface, expressed as a percentage.

Front

What does a low albedo indicate about a material?

Back

A low albedo indicates that the material absorbs more solar energy.

Front

What does a high albedo indicate about a material?

Back

A high albedo indicates that the material reflects more solar energy.

Front

How does albedo affect Earth's temperature?

Back

Materials with low albedo absorb more heat, potentially raising Earth's temperature, while high albedo materials reflect heat, keeping temperatures lower.

Front

What is the relationship between color and albedo?

Back

Generally, lighter-colored materials have higher albedo (reflect more sunlight), while darker-colored materials have lower albedo (absorb more sunlight).

Front

What happens to sea ice as global temperatures rise?

Back

As global temperatures rise, the amount of sea ice generally decreases over time.

Front

How can forests impact local temperatures?

Back

Forests can lower local temperatures due to their higher albedo compared to darker surfaces, as they absorb less solar energy.

Front

What is the significance of measuring albedo in climate studies?

Back

Measuring albedo helps scientists understand how different surfaces affect Earth's energy balance and climate change.

Front

What is an example of a surface with high albedo?

Back

An example of a surface with high albedo is snow or ice, which reflects a large portion of solar energy.

Front

What is an example of a surface with low albedo?

Back

An example of a surface with low albedo is asphalt or dark soil, which absorbs a significant amount of solar energy.
