Climate Change Review

What is the role of photosynthesis in the carbon cycle?

• Photosynthesis absorbs carbon dioxide from the atmosphere and releases oxygen.

• Photosynthesis releases carbon dioxide into the atmosphere and absorbs oxygen.

• Photosynthesis converts sunlight into heat energy for plants.

• Photosynthesis helps in the decomposition of organic matter.

What is the impact of deforestation on climate change?

• Deforestation increases carbon dioxide levels as fewer trees are available to absorb CO2.

• Deforestation has no significant impact on climate change.

• Deforestation decreases the amount of carbon dioxide in the atmosphere.

• Deforestation helps in increasing biodiversity.

What is carbon footprint?

• The total amount of greenhouse gases emitted directly or indirectly by an individual, organization, event, or product.

• A measure of the amount of carbon dioxide produced by a vehicle.

• The total weight of carbon in a product's lifecycle.

What is the difference between weather and climate?

• Weather refers to long-term atmospheric conditions, while climate is the short-term average of weather.

• Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather.

• Weather and climate are essentially the same thing, just different terms.

• Weather is what you expect, climate is what you get.

What is the significance of the year 1880 in climate studies?

• It marks the beginning of the Industrial Revolution.

• It is often used as a baseline year for measuring global temperature changes.

• It was the year when the first climate model was developed.

• It is the year when the first global temperature record was established.
