Impact of Carbon Emissions on Earth

Peter, an earth scientist at NASA, explains how fossil fuels like coal and natural resources like bananas are both products of plants storing energy from the sun. While bananas release carbon quickly, coal releases carbon that was stored millions of years ago, contributing to climate change. NASA uses satellites to study these changes, emphasizing the need to reduce fossil fuel use to prevent global warming.

What is the primary difference between a banana and a chunk of coal?

• Bananas are used for electricity generation.

• Both are made from animals.

• Coal is soft and delicious.

• Bananas are edible and coal is not.

How do both bananas and coal store energy?

• Through geothermal processes.

• By storing sunlight energy.

• Through water absorption.

• By capturing wind energy.

What happens to the carbon in a banana after it is consumed?

• It is released back into the atmosphere.

• It remains in the body permanently.

• It is converted into water.

• It turns into coal.

What is the difference between young fast carbon and ancient carbon?

• Young fast carbon is released shortly after being in the atmosphere.

• Ancient carbon is released quickly after consumption.

• Ancient carbon is found in bananas.

• Young fast carbon is stored for millions of years.

How long ago did plants take carbon out of the air to form coal?

• A few months ago.

• Millions of years ago.

• During the last century.

• In the last decade.

What would have happened to coal if humans did not dig it up?

• It would have turned into diamonds.

• It would have remained locked under the Earth.

• It would have evaporated.

• It would have become a renewable resource.

Why is carbon in the atmosphere a concern?

• It has no effect on the climate.

• It turns into oxygen.

• It acts like a blanket, warming the planet.

• It makes the planet cooler.

What does NASA use to study Earth's changes?

• Submarines.

• Microscopes.

• Satellites.

• Telescopes.

What are some of the changes observed by NASA due to increased carbon emissions?

• The land and ocean are cooling.

• The ice caps and glaciers are growing.

• The atmosphere is becoming less dense.

• The ice caps and glaciers are melting.

Why is it important to reduce the use of fossil fuels?

• To stop the formation of new glaciers.

• To keep the planet from getting too warm.

• To increase the Earth's temperature.

• To make more coal available.
