How does the earths system respond to global warming? know the various pathways and be able to explain from the perspective of positive/negative feedback of the system.
|
System- * increasing algae=lower co2 *plant growth=lower co2 *more snowpack = higher albedo *more cloud = higher reflection to outer space **Positive + *More cloud=higher greenhouse effect *melting of permafrost= more methane * reduction in snowpack = lower albedo.
|
|
|
What are the impacts of global warming?
|
*Atmosphere-temp. rising, precipitation rising, surface runoff, agricultural yield. *Hydrosphere- Declining glacier, rise in sea level *Biosphere- habitat, vector- borne disease.
|
|
|
What should we do?
|
Control GHG = kyoto protocol, AP6
|
|
|
What is global dimming? what are the methods of global dimming?
|
Global dimming is the reduction of shortwave radiation from the sun at the Earths surface
|
|
|
What are the lessons of the raccoons?
|
*concern with the fate of chemicals * Earth systems are interconnected (hydrology, biology, and geography)
|
|
|
Tell about the earths system
|
THe earch is a open and closed system it is open to energy but it is well budgeted; the earth is closed to matter but it is recycled. solar energy provides the major source of most earth cycles. The tilt of the earth leads to uneven spatial distribution of energy.
|
|
|
What is the energy budget? how much energy is reflected back to the outer space and absorbed by the atmosphere and land/ocean?
|
The energy budget is the earths climate system constantly tries to maintain a balance between the energy that reaches the earth from the sun and the energy that is returned to space.
|
|
|
What is the biogeochemical cycle? what are the four major components of the earth?
|
A biogeochemical cycle is a complete path a chemical takes through the four major components of the Earth. *Atmosphere (energy) *Hydrosphere (energy) *Lithosphere (geo) *Biosphere (bio)
|
|
|
What is hydrologic cycle? what are the functions of hydrologic cycle?
|
The movement and storage of water between the hydrosphere, atmosphere, lithosphere and biosphere. The function is desalination, transportation, and erosion - shapes landscape (Grand Canyon)
|
|
|
What is geologic cycle? what is it composed of? what is the role of each component?
|
the processes responsible for formation and change of earths materials, continental drift
|
|
|
What does co2 do if diffusion, photosynthesis, decomposition and respiration go up?
|
Co2 goes down with diffusion and photosyntesis and goes up with the other two
|
|
|
convergent vs. divergent
|
convergent comes together divergent seperates
|
|
|
transform
|
plates slide past one another
|
|
|
Rock types: Igneous, sedimentary, and metamorphic.
|
Igneous-cooled/solidified from magma or molten rocks
Sedimentary- lithification layers of sediment Metamorphic- transformation of existing rocks due to high pressure or temp. |
|
|
carbon sink
|
carbon "reservoir"
|
|
|
ecology
|
study of living places
|
|
|
biotiic
|
living producers consumers decomposers
|
|
|
abiotic
|
non living air water soil
|
|
|
soil
|
the residuum that results from weathering over an extended period of time
|
|
|
what is the importance of soil?
|
provides nutrients to the producers, helps cleansing water ans it is percolationg downward, recycles biodegradable wast, helps control the earths climate.
|
|
|
What is soil profile?
|
the vertical arrangment of the layers constitues a diagnostic property of soils.
|
|
|
holistic view
|
an ecological community is more than the sum of its parts
|
|
|
ecosystem threat
|
Habitat
Invasive species Pollution Population growth Overexploition |
|
|
Ecosystem management requires?
|
An appreciation of a species in its relation to the ecosystem and an understanding of the dynamic nature of the ecosystem.
|
|
|
succession
|
an ecosystem changes overtime and can undergo development through this process.
|
|
|
GIS
|
Geographic information system is an information system that can answer questions particulurly related to sptial issues.
