Match the terms with their definitions

Draggable item		Corresponding Item
Combustion		When plants use carbon dioxide to make sugar
Photosynthesis		When organisms breath out carbon dioxide
Ocean Exchange		When something is burned
Atmosphereic Carbon		When dead organisms are broken down
Respiration		The carbon gas that surrounds the earth
Decomposition/Decay		Carbon dioxide from the atmosphere dissolves into the ocean

Watch the video and answer the questions below:

What is a green house gas?

Gas that is green and comes from houses

Gas that traps heat from the sun causing the earth to warm

Gas that helps cool the earth by causing more ice to form

Carbon dioxide is a green house gas?

True

False

Greenhouse gases have stayed balanced for the past 150 years until what?

Humans started burning fossil fuels releasing more carbon dioxide into the atmosphere

Humans started planting more trees taking more carbon dioxide out to of the atmosphere 

Humans started breathing less, decreasing the amount of carbond dioxide in the atmosphere

What is happening as humans continue to burn fossil fuels, like gas ?

The earth is maintaining a perfect BALANCE of greenhouse gasses

The earth is warming due to more OXYGEN in the atmosphere

The earth is warming die to more CARBON dioxide in the atmosphere

The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels. This extra carbon dioxide is lowering the ocean’s pH, causing it to become more acidic . When ocean water becomes more acidic it interferes with the ability of marine organisms (including crabs, and snails) to build their shells and skeletons. Without a shell or skeleton, these organisms are either left unprotected to predators or never make it to birth.

What would happen to the marine organism population if the burning of fossil fuels by humans continues to increase?

The population of marine orgainsms would increase

The population of marine orgainsms would decrease

The population of marine orgainsms would stay the same
