• About 50 years

• About 100 years

• About 150 years

• About 200 years

Which gas does NOT trap heat?

• Oxygen

• Carbon Dioxide

• Nitrogen

What is the Greenhouse Effect?

• A process that cools the Earth by reflecting sunlight back into space.

• A natural process where certain gases in the Earth's atmosphere trap heat, keeping the planet warm enough to support life.

• A method of generating energy from the sun's rays.

• A phenomenon that occurs only in urban areas due to pollution.

What is the difference between climate and weather?

• Climate refers to the short-term atmospheric conditions in a region.

• Weather refers to the long-term average of weather patterns in a region.

• Climate refers to the long-term average of weather patterns in a region, while weather refers to the short-term atmospheric conditions.

• Weather is a measure of temperature and humidity only.

What is an example of a renewable energy source?

• Solar energy

• Natural gas

• Coal

• Nuclear energy

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

• The temperature goes down.

• The temperature stays the same.

• The temperature goes up.

• The temperature fluctuates wildly.

Name a greenhouse gas that traps heat.

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

What role do trees play in combating global warming?

• They release carbon dioxide into the atmosphere.

• They absorb carbon dioxide, helping to reduce greenhouse gas levels in the atmosphere.

• They increase the temperature of the earth's surface.

• They have no significant impact on global warming.

What do oceans do with sunlight?

• Oceans reflect sunlight because they are lighter in color.

• Oceans absorb sunlight because they are darker in color.

• Oceans scatter sunlight evenly across the surface.

• Oceans transmit sunlight without any absorption.

What would happen to Earth without the Greenhouse Effect?

• Earth would be too cold for most life forms to survive.

• Earth would become a desert with no water.

• Earth would experience extreme heat and drought.

• Earth would have a stable climate suitable for all life forms.
