Environmental Science Chapter 14 Test

Deforestation – area where land/ecosystems are protected from exploitation

Ecosystem services – resources provided by natural or artificial ecosystems

Geographic Information System – land-use tool

Infrastructure – roads, schools, power lines etc.

Environmental Science Chapter 14 Test

Overgrazing – excessive use of a grazing area

Selective cutting – certain trees removed only

Urban area – 2500 people or more (most Americans live here)

Urban crisis – rapid growth, cities cannot provide service for all citizens

Urban sprawl – rapid expansion into countryside

Wilderness area – land/ecosystems protected from exploitation

Environmental Science Chapter 14 Test

An example of land used as a protected area to preserve the scenery and ecosystems is the Grand Canyon.

National Farmland Protection Program - protect farmland from being developed.

Cutting only mature or medium-sized trees allows forests to recover from tree harvesting.

Range improvement – eliminate invasive plants and replace with native plants.

Environmental Science Chapter 14 Test

Rural areas - produce the resources

Heat islands produce increased precipititation

Open spaces in cities-lower summer temperatures-absorb carbon dioxide-filter pollutants from air and water

Environmental Science Chapter 14 Test

Inadequate urban infrastructures-traffic jams, substandard housing

Clear-cutting of forests-advantages – less expensive than selective-disadvantages – destroys habitats, soil erosion

Environmental Science Chapter 14 Test

Rangeland -well managed = limited grazing animals

= watering areas provided = native plants growing

-poorly managed = overgrazed, too many animals = grass killed, land becomes bare

= erosion occurs = nonnative plants move in = can no longer support grazing
