What is climate change?

Shifts in temperatures and weather patterns.

100

What is happening to the average temperature of the Earth, and why?

Increasing, due to the Greenhouse Effect

What is meant by a non-renewable resource?

A resource which is finite - will run out one day, and cannot be replenished.

200

What gas became more common when land plants had developed?

Oxygen

How did green plants reduce the amount of carbon dioxide in the atmosphere?

Plants and algae absorb carbon dioxide for photosynthesis.

Name 3 ways you could reduce your carbon footprint.

Switch off the lights, take the stairs, take shorter showers, power down electronics and unplug when not in use, do full loads of laundry, use fewer devices, switch to LED bulbs, reduce the amount of meat you consume or buy from local farms.

200

What pollutant causes a lack of oxygen in the body?

Carbon Monoxide

Condensation

300

How did oceans reduce the amount of carbon dioxide in the modern atmosphere?

Dissolved in the oceans when water vapour condensed.
