What does climate change mean?

• Longterm change to the weather patterns and the temperature in the world.

• The Earth's orbit around the sun is changing rapidly every year.

• Climate change only refers to the increase in daily temperatures.

• Climate change is caused by the moon's gravitational pull affecting Earth's atmosphere.

What's the difference between climate and weather?

• Weather is the average atmospheric conditions over a long period, while climate refers to the daily atmospheric conditions in a specific place.

• Weather refers to the short-term atmospheric conditions, while climate describes the long-term patterns of weather in a particular region.

• Weather and climate are the same; they both describe daily changes in temperature and precipitation.

• Weather refers to atmospheric conditions during extreme events only, while climate is the average of these extreme events.

What is global warming?

• Global warming is the natural process of the Earth cooling down over time.

• Global warming is the phenomenon of seasonal changes in temperature that occur every year.

• Global warming is the temporary warming of the Earth's surface caused by volcanic eruptions and solar flares.

• Global warming is the long-term increase in Earth's average surface temperature due to human activities, especially the emission of greenhouse gases.

What is CO2?

• CO2 is a harmful chemical produced only by factories and automobiles.

• CO2 is a type of nutrient that plants absorb from the soil to grow.

• CO2, or carbon dioxide, is a colorless, odorless gas naturally present in the Earth's atmosphere and produced by burning fossil fuels and respiration.

• CO2, or carbon dioxide, is a solid mineral found in Earth's crust and used in construction.

What do we refer to when we talk about "carbon emissions"?

• Carbon emissions refer to the release of oxygen into the atmosphere from natural sources like trees and plants.

• Carbon emissions are the release of carbon dioxide (CO2) and other carbon compounds into the atmosphere, primarily from burning fossil fuels, deforestation, and industrial processes.

• Carbon emissions are the process of capturing and storing carbon dioxide underground to prevent it from entering the atmosphere.

• Carbon emissions are the absorption of carbon dioxide by oceans and forests, reducing its concentration in the atmosphere.

What do we refer to when we talk about "carbon footprint"?

• A carbon footprint is the amount of carbon dioxide absorbed by a person or organization from the atmosphere each year.

• A carbon footprint is a measure of the physical footprint left by carbon particles in the environment.

• A carbon footprint is the total distance traveled by a person or organization in vehicles powered by fossil fuels.

• A carbon footprint is the total amount of greenhouse gases, including carbon dioxide and methane, that are emitted directly or indirectly by an individual, organization, event, or product over a specific period.

What's renewable energy?

• • Energy derived from sources that are naturally replenished on a human timescale, like the sun, water or wind.

• Energy obtained from fossil fuels like coal and natural gas.

• Energy generated through nuclear reactions.

• Energy produced from burning biomass.

What is the greenhouse effect?

• The greenhouse effect is the trapping of the sun's heat in the Earth's atmosphere due to the presence of greenhouse gases like carbon dioxide and methane.

• The greenhouse effect is the cooling of the Earth's surface caused by the reflection of sunlight by clouds.

• The greenhouse effect is the process of plants absorbing carbon dioxide and releasing oxygen.

• The greenhouse effect is the increase in Earth's temperature due to volcanic eruptions.

Which of the following is a consequence of global warming?

• Decrease in sea levels.

• Increase in the frequency and intensity of extreme weather events.

• Stabilization of global temperatures.

• Reduction in the amount of greenhouse gases in the atmosphere.

What is the primary cause of ocean acidification?

• Increased levels of carbon dioxide in the atmosphere being absorbed by the oceans.

• Oil spills and plastic pollution in the oceans.

• Natural volcanic activity under the sea.

• Excessive fishing and marine life depletion.
