Systems
What are the symbols used for storages, flows, and boundaries of a system?
Storages - box/circle
flows - arrows
boundaries - dotted lines
What is a human activity that results in habitat loss and a great release of carbon dioxide?
Deforestation
what is an independent variable?
The component of the experiment that is not being affected by the change/action
What is leaching?
when minerals are dissolved in water after moving through soil
What is the furtherest layer in the atmosphere?
Exosphere?
What is the difference between a closed system and isolated system?
In an closed system only energy can flow in and out. In an isolated system nothing can flow in or out.
In conservation efforts what are some factors to focus on?
size, arrangement, and shape
What is the difference between abiotic and biotic?
Abiotic refers to nonliving and biotic refers to living
In the soil system what are the storages?
organisms, nutrients, water, minerals, etc
What type of UV is the most dangerous and where is it absorbed?
UVC is the most dangerous but all of it is absorbed in the ozone layer
What happens to energy in tropic levels when heat radiates to the atmosphere?
The energy is lost
How does a greater population result in a greater amount of pollution?
More people means that there is a greater use of cheap non-perishable items.
What is the pyramid of biomass?
A model representing the biological mass present in each trophic level
What is the out come of when soil is over plowed or excessively terranced?
The soil loses it structure and nutrients therefore it cannot host/support any crops
What is the greenhouse effect?
Where greenhouse gases are released into the atmosphere and they trap heat from the sun.
What is the difference between transfers and transformations?
Transfer is when energy moves and transformations are when energy moves and changes form.
What are the Eenvironmental value systems?
Ecocentric, technocentric, and anthropocentric
Which pyramid says that two organisms with the same mass don't have to have the same energy content?
The pyramid of productivity
What is the difference between sandy soil and loam soil?
Sandy soil has a low primary productivity and loam soil has a high primary productivity
What are the factors that Hurricanes are measured by?
Winds, duration and rain
In the Ferrel cell what is the effect from cool air sinking?
It creates high pressure towards the surface.
How does the human consumption of natural resources result in a loss of biodiversity?
Because we are taking away these resources at a rate that they cannot be restored. This leaves many organisms with the challenge of having to adapt at rapid rates.
What are the formulas/measurements needed to find secondary productivity?
GSP, NSP, and respiration
Why is it a drawback for growing populations to have a larger consumption of meat and dairy products?
Because these foods come from organism in higher trophic levels meaning they require more energy and land
How does climate change effect the quality and quantity of natural disasters?
They follow a directly proportional relationship
