Oxygen Cycle Flashcards
How is oxygen cycle linked to carbon cycle
Photosynthesis and cellular respiration both include the oxygen and carbon cycle
What does the ozone layer do
Keeps the planet warm and protects from suns ultraviolet rays
Stromatolites
Dome shaped rocks, composed of thin layers of sediment press together.
Formed by cyanobacteria now fossilized
Banded iron formations
Forfeit, because oxygen produced cyanobacteria, which reacted and dissolved with iron in the oceans and precipitated out
How is oxygen link to photosynthesis and cellular respiration?
In the process of photosynthesis oxygen is released to the atmosphere
In the process of cellular respiration, oxygen Goes to organisms
O/C cycle:
Causes greenhouse affect
What are greenhouse gasss
When heat is trapped to earths surface = warm planet (greenhouse gases)
What causes global warming
When carbon dioxide is released in combustion reactions= Higher temperatures =. Rivers, overflowing, and rises in ocean levels
