What is the main source of methane in the atmosphere?

Car exhaust

Livestock farming

Volcanoes

Deforestation

Which gas contributes the most to the greenhouse effect?

Water vapor

Argon

Sulfur dioxide

Carbon monoxide

How do greenhouse gases warm the Earth?

By absorbing sunlight

By trapping heat from the Earth's surface

By reflecting heat back to space

By increasing cloud formation

Which activity does NOT directly increase greenhouse gas emissions?

Burning fossil fuels

Planting trees

Deforestation

Driving petrol cars

What are the products of complete combustion of a hydrocarbon?

a) Carbon dioxide and water

b) Carbon monoxide and water

c) Carbon and water

d) Hydrogen and oxygen

Which gas is a product of incomplete combustion?

a) Carbon dioxide

b) Carbon monoxide

c) Oxygen

d) Nitrogen

Why is carbon monoxide dangerous?

a) It causes explosions

b) It is flammable

c) It prevents oxygen transport in the blood so is toxic 

d) It reacts with water vapor

Soot is produced during:

a) Complete combustion

b) Incomplete combustion

c) Photosynthesis

d) Neutralization

Which of these is NOT a sign of incomplete combustion?

a) Soot formation

b) Blue flame

c) Yellow flame

d) Carbon monoxide production

What does "carbon footprint" measure?

The amount of oxygen used by humans

The amount of greenhouse gases emitted by activities

The amount of coal burned per year

The amount of trees planted globally

Which activity has the largest carbon footprint?

Cycling to school

Driving a petrol car

Using solar panels

Growing vegetables in a garden

Reducing your carbon footprint includes:

Flying more frequently

Using public transport

Leaving lights on overnight

Using non-renewable energy sources

Which of these actions decreases carbon emissions?

Eating more meat

Using LED light bulbs

Burning more coal

Cutting down forests

A person with a high carbon footprint is likely to:

Travel a lot by plane

Use renewable energy

Drive an electric car

Plant many trees

What is the main cause of global warming?

Increased sunlight

Burning fossil fuels

Volcanoes erupting

Decreased oxygen levels

Which of the following is a consequence of global warming?

Rising sea levels

Decreased plant growth

Lower global temperatures

Formation of glaciers

Global warming can lead to:

More extreme weather events

Stable ocean temperatures

Less rainfall worldwide

Slower melting of ice caps

Which gas contributes most to global warming?

Nitrogen

Oxygen

Methane

Argon

One effect of global warming is:

Ocean cooling

Habitat destruction for animals

Increase in volcanic eruptions

Decrease in greenhouse gases

Deforestation increases carbon dioxide levels because:

Trees absorb carbon dioxide

Trees release oxygen

Trees use nitrogen

Trees block sunlight

Which activity contributes most to deforestation?

Urbanization

Cycling

Solar farming

Recycling

One effect of deforestation is:

Improved air quality

Loss of biodiversity

Decrease in fossil fuels

Increase in water supplies

How can deforestation be reduced?

Clear more land

Switch to sustainable farming practices

Burn more wood

Build more cities

Fossil fuels include:

Coal, oil, and natural gas

Wind, solar, and nuclear energy

Biomass and ethanol

Water, methane, and oxygen

What is a disadvantage of using fossil fuels?

They are renewable

They are non-renewable

They release oxygen when burned

They produce no pollution

Fossil fuels are formed from:

Dead plants and animals over millions of years

Rocks cooling quickly

Lava hardening

Minerals dissolving in water

Burning fossil fuels releases:

Oxygen

Methane

Carbon dioxide

Helium

Which is NOT an alternative to fossil fuels?

Solar energy

Wind energy

Oil

Hydroelectric power
