here are the answers to the Land Resources Unit Review Practice:

A: it causes narrower beaches and it can cause lower beach elevations
Drag each sustainable farming practice to indicate whether it is best suited for the desert, the rain forest, or mountains.
A: (Desert: green houses, hydroponics)-(Rain forest: alley cropping)-(Mountains: terrace farming)
Which of the following is a negative impact that flooding can have on the environment?
A: reduction of microbial populations
Why is beach nourishment considered mostly a short-term strategy for fighting beach erosion?
A: It must be repeated every 5 to 7 years
When creating an urban green space, which of the following needs to be determined in order for the space to provide the most benefit to the most people?
A: The proximity of the space to the city's population
How do green roofs compare to traditional roofs?
A: Green roofs initially cost more to install
Drag each effect of agroforestry in the rain forest to indicate whether it is a cost or a benefit.
A: (Cost: higher start-up expenses, increased need for labor)-(Benefits: higher amount of carbon storage, increased numbers of pollinating insects, higher amount of nitrogen in the soil)
Drag each phrase to indicate which flood mitigation technique it describes.
A: (Floodplain management: protects buildings in low-lying areas prone to floods)-(stormwater management: reduces water runoff into streets, lawns, and other sites, enhanced by the addition of urban green spaces)-(elevated structures: used mainly on the coast, raises structures above flood level)
Drag each phrase describing flood mitigation projects to the appropriate box to indicate whether it is a cost or a benefit.
A: (Cost: initial design and construction, ongoing Maintenace)-(Benefit: employment opportunities, lower insurance costs, protection of infrastructure)
Drag each phrase into the correct column for the beach erosion strategy it describes.
A: (Jetty: hard structure built perpendicular to shore, can cause sand buildup on updrift side of structure)-(Beach nourishment: brings in more sand to replace erosion)-(Seawall: hard structure that also provides flood protection, prevents erosion by directing waves back to ocean)
