What role do wetlands play in regulating the climate?

They absorb carbon dioxide and store it

They release more greenhouse gases into the atmosphere

They reduce the amount of water in the atmosphere

They increase the temperature of nearby regions

What effect does deforestation have on photosynthesis and the carbon cycle?

It decreases the rate of photosynthesis, leading to more CO2 in the atmosphere

It increases the rate of photosynthesis

It has no effect on photosynthesis

It increases the amount of CO2 absorbed by plants

How does urbanization affect the local climate?

It makes urban areas warmer due to changes in albedo

It decreases the local temperature

It increases the amount of vegetation in the area

It reduces the amount of carbon dioxide in the atmosphere

Why is the increase in CO2 levels since the Industrial Revolution concerning?

It has led to the warming of Earth's atmosphere

It helps plants grow more efficiently

It has caused a decrease in global temperatures

It causes ice sheets to grow thicker

How do rising global temperatures influence precipitation patterns?

They lead to more intense rain in some areas and droughts in others.

They lead to more consistent rainfall in all areas

They reduce evaporation from the oceans

They cause all areas to experience equal rainfall

Which of the following actions could help reduce the effects of climate change in cities?

Planting more trees in urban areas

Increasing the number of coal-powered plants

Reducing the use of solar energy

What does the albedo effect describe?

The ability of an area to reflect sunlight

The amount of CO2 absorbed by forests

The amount of energy absorbed by oceans

The heat trapped in the atmosphere

What impact does melting ice have on the ocean?

It raises sea levels by adding water from land-based ice sheets

It cools the ocean and reduces ocean circulation

Why is the increase in carbon dioxide (CO2) from human activities a major cause of global warming?

CO2 traps heat in the atmosphere, causing the Earth to warm

CO2 causes the ozone layer to thicken

CO2 increases solar radiation reaching Earth

CO2 reflects sunlight away from Earth

What is one effect of rising sea levels on coastal communities?

It causes more frequent storm surges and flooding

It decreases the temperature of coastal waters

It helps to reduce coastal erosion

What is the primary source of CO2 emissions from human activities?

Burning fossil fuels like coal, oil, and natural gas

If we reduced global carbon emissions by 50%, how long would it take for the climate to return to pre-industrial levels?

It would take at least 100 years, as the atmosphere would still contain high levels of CO2

The climate would return to pre-industrial levels within a decade

The climate would return to pre-industrial levels almost immediately

There would be no noticeable change in global temperatures, as CO2 emissions do not affect the climate

Why are cities important in the fight against climate change?

Cities are major sources of carbon emissions and can lead the way in reducing them

They produce more greenhouse gases than any other area of land

They are the only places where fossil fuels are burned

Cities contribute less to global warming than rural areas

What is one example of a solution to climate change that involves changing urban infrastructure?

Designing cities with more trees, green roofs, and public transit to reduce emissions

Increasing the use of fossil fuels for energy

Building more highways for increased car use

Expanding land use and removing green spaces

What is ocean acidification?

The decrease in pH levels of the ocean caused by excess carbon dioxide

The process by which oceans become less salty

The increase in ocean temperature due to global warming

The increase in oxygen levels in ocean waters

What causes coral bleaching?

Stress on corals due to warmer water temperatures and other environmental factors

Why is coral bleaching considered a sign of global warming?

It happens when higher water temperatures stress corals, causing them to expel algae

It occurs when water temperatures become too cold for coral to survive

It is caused by an increase in oceanic carbon dioxide, which prevents bleaching

It results from the increase in freshwater flowing into the oceans

What role does carbon dioxide play in ocean acidification?

It reacts with water to form carbonic acid, lowering the ocean's pH

It decreases the amount of oxygen in the ocean, leading to acidification

It raises the pH of the ocean, making it more alkaline

It has no effect on the pH of the ocean

What has been an observable trend in global temperatures over the past century?

A gradual and significant increase in average global temperatures

A consistent decrease in global temperatures

No noticeable change in global temperatures

A temporary rise followed by a steady decline

How does animal waste contribute to CO2 emissions?

Decomposing animal waste releases CO2 into the atmosphere

Animal waste is composted, which absorbs CO2 from the atmosphere

Animal waste helps reduce CO2 in the atmosphere

Animal waste has no effect on CO2 emissions

Which option best explains how waste management can add CO₂ to the atmosphere?

Trucks and burning waste release CO₂.

Recycling releases lots of CO₂.

Plastic quickly becomes CO₂ in landfills.

Why doesn’t planting crops after deforestation fully make up for the CO₂ impact of cutting down forests?

Forests store more carbon for longer than crops.

Crops release no CO₂ when harvested.

Crops absorb CO₂ faster than forests.

Crops don’t use sunlight for photosynthesis.
