Albedo & Greenhouse Effect

Front

What is Albedo?

Back

Albedo is the measure of how much sunlight is reflected by a surface. It is expressed as a percentage; a higher albedo means more sunlight is reflected.

Front

What is the Greenhouse Effect?

Back

The Greenhouse Effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, which helps to keep the planet warm.

Front

What happens to Earth's temperature if more greenhouse gases are released?

Back

Earth's temperature will increase.

Front

What is Climate?

Back

Climate refers to the long-term average weather conditions in a particular region over a significant period.

Front

What is Weather?

Back

Weather describes the atmospheric conditions and short-term changes in a specific place at a specific time.

Front

How does the presence of greenhouse gases affect Earth's temperature?

Back

The presence of greenhouse gases increases Earth's temperature by trapping heat in the atmosphere.

Front

What would happen to Earth without greenhouse gases?

Back

Earth would be much colder without greenhouse gases.

Front

What is the relationship between albedo and temperature?

Back

Surfaces with high albedo reflect more sunlight, which can lead to cooler temperatures, while surfaces with low albedo absorb more sunlight, leading to warmer temperatures.

Front

How does vegetation affect local temperatures?

Back

Vegetation can lower local temperatures by providing shade and increasing albedo, as grass and trees reflect more sunlight compared to dark surfaces.

Front

What is an example of a high albedo surface?

Back

An example of a high albedo surface is snow, which reflects most of the sunlight that hits it.
