Water cycle
Processes of the water cycle
What is evaporation, condensation, and precipitation
Define carbon cycle
What is the process by which carbon moves within and between organisms and their physical environment
Define Nitrogen Cycle
What is the process by which the nitrogen gas is fixed into nitrates by bacteria or lightning to be used by plants and then back into nitrogen gas by bacteria after plants and animals die or give off waste.
4 steps - Fixation, Nitrification, Consumption, Denitrification
~71% of this on earth

~78.08% of this is in the earth atmosphere
What is nitrogen
Plants losing or giving off water is called
What is transpiration
Human activities affect the levels of _____ and _____ in the atmosphere
What is carbon and oxygen
* Nitrogen is also acceptable
What is a nitrate?
a nitrate is formed by nitrogen fixation by bacteria or lightning, NO3
~20.95% of this is in the atmosphere
What is oxygen
3 bodies of water is evaporated by the sun
What molecule is carbon normally found in
What is carbon dioxide
Explain the process of Photosynthesis
Formula for photosynthesis
What is 6CO2+6H2O + light energy = C6H12O6+6O2
Extra carbon are in the atmosphere because of
What is burning fossil fuels
Name one way Nitrogen can be beneficial and one way Nitrogen can be harmful.
Harmful - High nitrate levels in our water, runoff, dead zones, damage to the fishing economy in the South
Explain the process of cellular respiration
When an organism's cells take in oxygen and glucose and turn it into water and energy (ATP)
Formula for Respiration
What is C6H12O6+6O2=6H2O+6CO2+Energy (ATP)
