Coral Bleaching, Ocean Acidification and Global Warming

Oceans are important to our environment and atmosphere because... (Choose all that apply)

• They absorb heat and carbon dioxide.

• They hold 97% of the world's water

• They generate 50% of the oxygen we breathe?

• They create opportunities for family outings and activities.

Choose all of the leading contributors of carbon dioxide that are contributing to global warming.

• forest fires

• human breathing (respiration)

• car exhaust

• factory pollution

What is climate change?

• The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

• a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, and other pollutants.

• The action of clearing a wide area of trees.

• a change in global or regional climate patterns, in particular a change attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.

Which of these is a consequence of global warming to our oceans? (choose all that apply)

• Acidification: Ocean is becoming more acidic.

• Sea level is rising due to land ice melting.

• Coral bleaching which results in them dying.

• Animals are getting strangled by plastic 6 pack rings.

Which of the following is a consequence of global warming? (Choose all that apply)

• Seas rising (flooding)

• Loss of habitat for animals.

• More severe storms and weather.

• Increased forest fires and drought.

Man made carbon dioxide comes from the burning of fossil fuels.  An example of a fossil fuel is

• wood
• oil
• shale

Ocean acidification begins with 

• pollution from ships
• carbon dioxide released from combustion
• dumping of waste from cities into the ocean

Carbon dioxide and seawater combine to form

• calcium carbonate
• carbon monoxide
• carbonic acid 

The H+ ion is a(n)

• acid
• base
• neutral

Marine organisms make their shells from calcium and

• chloride
• carbonate
• seawater
