Understanding Climate Change

What is climate change?

• Climate change is the increase in the number of natural disasters.

• Climate change is the long-term alteration of temperature and typical weather patterns in a place, primarily driven by human activities.

• Climate change is a seasonal variation in weather patterns.

• Climate change refers to the immediate changes in weather conditions.

Name one greenhouse gas.

• oxygen

• nitrogen

• helium

• carbon dioxide

What is the main cause of climate change?

• Increase in greenhouse gases due to human activities.

• Increased solar activity

• Deforestation without any human impact

• Natural fluctuations in the Earth's climate

How does deforestation contribute to climate change?

• Deforestation helps to preserve local ecosystems.

• Deforestation has no impact on carbon levels in the atmosphere.

• Deforestation increases rainfall and cools the climate.

• Deforestation contributes to climate change by increasing carbon dioxide levels in the atmosphere and disrupting local ecosystems.

What is the greenhouse effect?

• The greenhouse effect refers to the increase in Earth's gravity due to rising temperatures.

• The greenhouse effect is the cooling of Earth's surface due to the reflection of sunlight.

• The greenhouse effect is caused by the depletion of ozone in the stratosphere.

• The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

List one effect of climate change on weather patterns.

• Stable weather patterns year-round.

• Decreased rainfall in all regions.

• Increased agricultural productivity.

• Increased frequency of extreme weather events.

What is global warming?

• A temporary increase in temperature due to seasonal changes.

• Global warming is the long-term rise in Earth's average surface temperature due to human activities.

• The cooling of the Earth's atmosphere caused by volcanic eruptions.

• A natural phenomenon that occurs every few decades.

Define renewable energy.

• Energy that cannot be replaced once used, such as nuclear energy.

• Energy generated from non-renewable sources like natural gas.

• Renewable energy is energy from sources that are naturally replenished, such as solar, wind, and hydro.

• Energy derived from fossil fuels like coal and oil.

What is the role of carbon dioxide in the atmosphere?

• Carbon dioxide helps regulate Earth's temperature and is vital for photosynthesis.

• Carbon dioxide contributes to the depletion of the ozone layer.

• Carbon dioxide is a primary source of oxygen in the atmosphere.

• Carbon dioxide is a major pollutant that harms all living organisms.

Name one way to reduce carbon footprint.

• Use public transportation

• Leave lights on when not in use

• Use disposable plastic bags

• Drive a gas-guzzling SUV
