Understanding Our Planet's Blanket

What is the greenhouse effect?

• The process by which plants grow in a greenhouse

• The warming of Earth's surface due to the trapping of heat by the atmosphere

• The cooling effect that happens at night

• The effect of green-colored houses on the environment

Which of the following is NOT a greenhouse gas?

• Carbon dioxide (CO2)

• Methane (CH4)

• Oxygen (O2)

• Nitrous oxide (N2O)

How does the greenhouse effect on Venus compare to that on Earth?

• It is weaker because Venus is farther from the Sun

• It is stronger due to the high concentration of greenhouse gases in Venus' atmosphere

• It is non-existent because Venus has no atmosphere

• It is the same as on Earth

What human activity contributes the most to the greenhouse effect?

• Planting trees

• Recycling

• Burning fossil fuels

• Using solar panels

Which gas is the primary contributor to the greenhouse effect on Earth?

• Water vapor (H2O)

• Carbon dioxide (CO2)

• Methane (CH4)

• Chlorofluorocarbons (CFCs)

What can humans do to reduce greenhouse gas emissions from cars?

• Drive more frequently

• Use public transportation or carpool

• Increase the use of diesel engines

• Avoid regular vehicle maintenance

Which renewable energy source helps reduce greenhouse gas emissions?

• Coal

• Natural gas

• Solar power

• Nuclear power

How do trees help combat the greenhouse effect?

• By providing shade and cooling the ground

• By absorbing carbon dioxide and releasing oxygen

• By reflecting sunlight back into space

• By increasing humidity and rainfall

What is the role of livestock in the production of greenhouse gases?

• Livestock consume greenhouse gases, reducing them in the atmosphere

• Livestock have no impact on greenhouse gas levels

• Livestock produce methane, a potent greenhouse gas, during digestion

• Livestock increase oxygen levels which intensify the greenhouse effect

Which of the following is a way to reduce energy consumption in homes?

• Leaving lights on when not in use

• Using incandescent bulbs instead of LED bulbs

• Insulating homes to reduce heating and cooling needs

• Increasing the thermostat setting in winter
