Learning Objective: I can develop a model to describe the cycling of Earth’s materials and the flow of energy that drives this process.
Notes:
First law of thermodynamics - the total amount of energy in a closed system cannot be created nor destroyed, but can be changed from one form to another
Earth as a Closed System
Elements and compounds that make up nutrients move continuously through the 4 spheres on earth (atmosphere, lithosphere, hydrosphere, biosphere) in cycles called the biogeochemical cycles
As nutrients move through the cycles, they can accumulate and remain in certain portions for periods of time; these temporary storage sites (e.g. atmosphere, ocean) are called reservoirs.
Rubric, requirements, due date is Tuesday 11/13
Good resources:
-The 'Living in the Environment' textbook p.66
-Fast Track to a 5 p.89
-Water, Carbon, & Nitrogen cycles explained with interactive diagrams
-Windows to the Universe website
-Human Impact on Biogeochemical Cycles
-5 Biogeochemical Cycles with LOTS of vocab (short 3 min video, no audio)
If you were absent on 11/13, here is your cycle:
Period 1 - Juliana: phosphorus; Alexia: nitrogen; Karime: carbon
