P2U2 02The Enhanced Greenhouse Effect and Global Warming

What human activities contribute to the Enhanced Greenhouse Effect?

• Burning fossil fuels, deforestation, cattle ranching, rice farming, using artificial fertilizers, and cement production.

• Planting trees and restoring forests.

• Using renewable energy sources like solar and wind.

• Reducing waste and recycling materials.

What is the Enhanced Greenhouse Effect?

• A natural phenomenon that regulates Earth's temperature.

• The observed increase in global temperatures since the Industrial Revolution, attributed to human activities and increased greenhouse gas emissions.

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

• The effect of greenhouse gases on weather patterns without impacting global temperatures.

What is the significance of the Industrial Revolution in global warming?

• It led to a decrease in global temperatures due to reduced emissions.

• It marked the beginning of a significant rise in global temperatures due to increased carbon dioxide emissions from burning fossil fuels.

• It had no impact on global temperatures or climate change.

• It resulted in the development of renewable energy sources that reduced carbon footprints.

Which countries are the largest contributors to CO2 emissions?

• China and the United States

• India and Brazil

• Germany and Japan

• Russia and Canada

What sectors are dominant in CO2 emissions for major emitting countries?

• Transportation

• Agriculture

• Energy

• Waste Management

How do greenhouse gases affect Earth's temperature?

• They have no effect on Earth's temperature.

• They cause Earth's temperature to decrease.

• An increase in greenhouse gases leads to more heat being retained, causing Earth's temperature to rise.

• They only affect the temperature of the atmosphere, not the surface.

What percentage of atmospheric gases do greenhouse gases constitute?

• Less than 1%

• About 5%

• Approximately 10%

• Around 20%

Why is the increase in greenhouse gases significant despite their small percentage?

• They are the primary source of energy for the planet.

• Changes in their concentration have a huge effect on the balance of natural processes.

• They are easily absorbed by the ocean, reducing their impact.

• They are only harmful in large quantities, which is rare.

What are the main sources of CO2 emissions?

• Burning fossil fuels, deforestation, agriculture, and cement production.

• Solar energy production, wind energy, hydroelectric power, and geothermal energy.

• Recycling, composting, public transportation, and electric vehicles.

• Planting trees, reducing waste, using less water, and eating less meat.
