Holt Environmental Science: Land Use and Energy Chapter 14 & 18 Hug

STUDY
PLAY
rural land
relatively few people and large areas of open
urban lands
buildings, roads, houses, and industry(cities)
infrastructure
roads, sewers, transportation systems, schools, and hospitals
heat island
increased temperature in a city due to generated and trapped heat
geographic information system
computerized system for sorting, manipulating, and viewing geographic data
land-use planning
advanced decisions about how land will be used
wilderness
protected land
urban sprawl
rapid expansion of a city into the surrounding countryside
rural
low population density
urbanization
Movement of people from rural areas to cities
deforestation
The removal of trees faster than forests can replace themselves.
parks and preserves
land used for recreation and scenic enjoyment, and for preserving native animal and plant communities and ecosystems
range land
land that is used to graze livestock and wildlife
forests
land used for harvesting wood, wildlife, fish, nuts, and other resources
farmland
land used to grow plants for food and fiber
green spaces
improvement to urban areas moderates temperature, controls rainwater runoff, and adds aesthetic value
ecosystem services
resources produced by natural and artificial ecosystems
Renewable energy
is energy from sources that are constantly being formed.
Active solar heating
is the gathering of solar energy by collectors that are used to heat water or heat a building.
Passive solar heating
is the use of sunlight to heat buildings directly.
Biomass fuel
consists of plant material, manure, or any other organic matter that is used as an energy source.
Hydroelectric energy
is electrical energy produced by falling water.
Geothermal energy
is the energy produced by heat within Earth.
Alternative energy
describes energy that does not come from fossil fuels and that is still in development.
Ocean thermal energy conservation (OTEC)
is the use of temperature differences in ocean water to produce electricity.
fuel cell
is a device that produces electricity chemically by combining hydrogen fuel with oxygen from the air.
Energy efficiency
is the percentage of energy put into a system that does useful work. For example, on CFL bulbs less energy is wasted on heat.
Energy conservation
is the process of saving energy by reducing energy use and waste.
