Climate Change

What is the direct cause of rising sea levels?

• Melting Sea Ice

• Melting Land Ice

• Climate Change

Possible human solutions for limiting global warming and climate change are...

• being more energy-efficient

• using renewable sources of energy

• removing carbon from fossil fuel emissions

• all of the above

MAIN greenhouse gas responsible for Climate Change is:

• nitrogen

• carbon

• carbon dioxide

• methane

Select the greenhouse gas(es)

• CO2

• Methane

• Oxygen

• All of the above

Which natural process removes carbon dioxide from the atmosphere?

• forest fires

• volcanic eruptions

• cellular respiration

• photosynthesis

Visible light reaches Earth’s surface while infrared light is trapped as heat. Which characteristic of Earth’s atmosphere causes this to happen?

• the hole in the ozone
• the greenhouse effect
• atmospheric pressure
• the inversion layer

The average temperature of the surface of Earth has increased approximately 1°C in the past century. Which reason best explains this increase in temperature?

• lower levels of ozone in the atmosphere
• lower levels of nitrogen in the atmosphere
• higher levels of carbon dioxide in the atmosphere
• higher levels of oxygen in the atmosphere

Which of the following is the best conclusion that can be made from this graph?

• atmospheric carbon dioxide levels have been decreasing since 1960
• Hawaii has a lot of carbon dioxide
• humans have been working hard to decrease carbon dioxide levels
• atmospheric carbon dioxide levels have increased steadily since 1960

How does the greenhouse effect work?

• Greenhouse gases reflect the sun's energy, causing it to warm the Earth.

• Greenhouse gases directly warm oceans and cause dramatic weather.

• Greenhouse gases absorb the sun's energy, slowing or preventing heat from escaping into space.

• Oceans absorb greenhouse gases, which cause the Earth's temperature to rise.

A carbon ________ is the total greenhouse gas emissions caused by an individual, event, organization, service, place or product.
