Greenhouse Effect and Albedo

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, thus warming the planet.

What is albedo?

Back

Albedo is the measure of how much light that hits a surface is reflected without being absorbed. It is expressed as a percentage.

How does a high albedo surface affect temperature?

Back

A high albedo surface reflects more sunlight, which helps to keep the area cooler compared to surfaces with low albedo that absorb more heat.

What are some examples of high albedo surfaces?

Back

Examples include ice, snow, and light-colored materials.

Front

What are some examples of low albedo surfaces?

Back

Examples include forests, oceans, and dark-colored materials.

Front

What is the relationship between ice melting and global temperature?

Back

When ice melts, it reduces the Earth's albedo, leading to increased absorption of sunlight and a rise in global temperatures.

What is the difference between the greenhouse effect and global warming?

Back

The greenhouse effect is a natural process that warms the Earth, while global warming refers to the recent increase in Earth's average temperature due to human activities.

What role do carbon dioxide levels play in the greenhouse effect?

Back

Increased levels of carbon dioxide enhance the greenhouse effect by trapping more heat in the atmosphere.

What natural events can release carbon dioxide?

Back

Natural events such as wildfires, volcanic eruptions, and the decomposition of organic matter release carbon dioxide into the atmosphere.

Front

How often do El Niño events occur?

Back

El Niño events typically occur every 2-7 years.
