Global Warming Quiz

What is global warming?

• A decrease in the average temperature at Earth's surface

• An increase in the average precipitation on Earth

• A decrease in the average precipitation on Earth

• An increase in the average temperature at Earth's surface

Answer explanation

Global warming refers to the increase in Earth's surface temperature. It is caused by the accumulation of greenhouse gases in the atmosphere, trapping heat and leading to climate change.

What is the main cause of the rise in global surface temperatures?

• Natural variations in the sun's energy output

• Deforestation leading to increased greenhouse gases

• Burning of fossil fuels releasing carbon dioxide

• Methane emissions from agricultural activities

Answer explanation

The main cause of the rise in global surface temperatures is the burning of fossil fuels, which releases carbon dioxide.

What is the predicted range of Earth's average surface temperature rise by 2100 if warming continues unchecked?

• 0.5 to 2.5 Fahrenheit degrees

• 2.0 to 11.5 Fahrenheit degrees

• 5.0 to 15.0 Fahrenheit degrees

• 8.0 to 20.0 Fahrenheit degrees

Answer explanation

The predicted range of Earth's average surface temperature rise by 2100 if warming continues unchecked is 2.0 to 11.5 Fahrenheit degrees. This range represents the correct choice.

What is the impact of global warming on sea level rise by 2100?

• A decrease in sea level

• No significant impact on sea level rise

• A rise of 5 to 20 inches

• A rise of 16 to 40 inches

Answer explanation

Global warming will cause a rise of 16 to 40 inches in sea level by 2100, highlighting the correct choice.

What is the effect of global warming on the Arctic region?

• Increase in sea ice coverage

• No impact on Arctic species

• Threat to polar bear population

• Decrease in average temperature

Answer explanation

Global warming poses a threat to the polar bear population in the Arctic region.

What is the primary method to limit carbon dioxide emissions?

• Increasing fossil fuel consumption

• Burning of more fossil fuels

• Energy conservation and efficiency

• Deforestation for industrial expansion

Answer explanation

The primary method to limit carbon dioxide emissions is through energy conservation and efficiency.

What is personal energy conservation?

• Increasing energy consumption

• Reducing consumption of goods and services

• Driving instead of walking or biking

• Using more electronic devices

Answer explanation

Personal energy conservation refers to reducing consumption of goods and services, which helps in minimizing energy usage and promoting sustainability. This choice is correct as it aligns with the goal of conserving energy and reducing environmental impact.

What is the impact of rising temperatures on human health?

• Increase in cold-related deaths

• No impact on human health

• Reduction in heat-related deaths and illnesses

• More deaths and diseases caused by extreme weather events

Answer explanation

Rising temperatures lead to more deaths and diseases caused by extreme weather events.

What is the effect of warming seas on coral reefs?

• No impact on coral reefs

• Expansion of coral reef habitats

• Increase in coral reef population

• Coral bleaching and death

Answer explanation

Warming seas cause coral bleaching and death, not expansion or increase in population. No impact is incorrect.

What is the main source of greenhouse gases causing global warming?

• Industrial waste emissions

• Natural forest fires

• Burning of fossil fuels

• Volcanic eruptions

Answer explanation

The main source of greenhouse gases causing global warming is the burning of fossil fuels.
