Landfills
What is a landfill?
A place where waste is buried to prevent pollution and manage our waste.
What are the four Earth subsystems?
Atmosphere, biosphere, geosphere, and hydrosphere.
The huge railroad network (tracks, trains, crossing guards, stations, levers and switches, docks, etc.) is an example of a _______________________.
System
What is the role of a producer in the biosphere?
To use photosynthesis to generate energy.
How do landfills prevent waste from leaving the site?
Compacting and/or covering it daily with industrial soil.
A volcanic eruption occurs in which subsystem?
Geosphere
A group of parts working together to accomplish a goal/function/purpose.
What do consumers do in the biosphere?
Eat producers, consumers, and decomposers.
How do landfills dispose of leachate from waste?
It gets collected and taken away from the waste to evaporate.
Evaporation is something that occurs in which subsystem?
Hydrosphere
A train (engine, lights, horn, passenger carts, wheels, smoke stack, etc.) is part of a larger system (the railroad network). This is an example of a __________________________________.
Subsystem.
What is the role of decomposers?
The break down dead organisms and other waste to recycle nutrients back into soil.
How does a landfill deal with methane from waste?
First, they use the methane (gas) to power buildings by spinning a generator. Then they burn the methane to destroy it, turning it into less harmful gasses.
Consumers eating producers is something that occurs in which subsystem?
Biosphere
What is a subsystem?
A smaller system that is part of a larger system.
A simple line of arrows from producers to consumers of larger and larger sizes is a _____________________________.
Food chain
What is another use for methane at many landfills?
To power buildings by pushing the methane through a generator.
Which systems work together to produce storms?
Atmosphere and hydrosphere
Is Earth a system? Why or why not?
What do the arrows of a food chain and a food web show?
Where the energy in a system is going.
