What are the two stages of the carbon cycle?
Fast(living organisms) and Slow(dead organisms)
Def: Photosynthesis
When plants + algae use solar energy to convert carbon dioxide into glucose
Def: Respiration (Aerobic)
The process where cells convert glucose and oxygen into energy, carbon dioxide and water.
De: Exchange
The amount of carbon that is released from the ocean=the amount of atmospheric carbon dioxide that is diffused into the ocean
Def: Burial
Slow geological process that stores carbon in underground sinks. (soil)
Def:Extraction
Humans extracting fossil fuels for combustion.
Def: Combustion
Fossil fuels and plant matter are converted to carbon dioxide. Usually through fires or burning, volcanoes.
Def: Greenhouse Gases
Gases in the atmosphere that re-emit heat back to the Earth’s surface.
Sig: Greenhouse Gases
Helps keeps Earth’s surface within the range of temperature where life can flourish.
How does carbon dioxide increase the temperature of the Earth?
Excess carbon dioxide in the atmosphere increases the retention of heat energy in the atmosphere. Which therefore increases the temperature of the Earth.
How does cutting down trees add carbon dioxide to the atmosphere?
Trees store large amounts of carbon in their wood. Cutting and burning down trees will therefore increase carbon dioxide in the atmosphere. Without replanting enough trees to recapture the carbon, carbon dioxide in the atmosphere will increase.
Def: Global Warming
Increase in global temperatures due to humans producing greenhouse gases.
Def: Carbon Sinks
Reservoir that absorbs more carbon dioxide than it releases. Ocean (plant algae), Forests, soil
Def: Carbon Sources
Processes that add carbon to the atmosphere
Ex: Carbon Sources
Fossil fuel, Animal (burps and farts), Deforestation
Photosynthesis in a sink or source?
Sink. Ex. As trees get taller they pull carbon from the atmosphere
The cellular respiration a sink or a source?
A source.
Both cellular respiration and photo synthesis ________ and __________.
Happen quickly and balance each other out
How will increasing carbon dioxide in the atmosphere affect the oceans?
Due to direct exchange, more carbon dioxide will be diffused into the ocean leading to ocean acidification. This will lower the pH level of the ocean which will eventually create an uninhabitable ocean.
