since

Environmental effects of deforestation

More air pollution, habitat loss.

Results of urban sprawl

Less rural areas, more connected cities.

Strategies to improve rangeland management

Field rotation, water dispersion, removal of invasive species, fencing to rotate livestock.

Majority of U.S. population living areas

Urban areas.

Effects of heat islands on weather patterns

Warmer temperatures in those areas and increased rainfall.

Three characteristics of an urban area

Higher population, more resources, warmer weather, increased traffic.

Definition of the urban crisis

Too many people too fast, overloaded infrastructure.

Environmental benefits of open spaces in cities

Higher air quality, less water run-off, emotional benefits.

First established national park

Yellowstone National Park.

Importance of preserving rural areas

Less CO2 emissions, abundant resources.

Importance of preserving farmlands

This is where we get most of our food.

Where resources are produced

Rural areas.

Challenges of land-use planning

Making all areas more efficient and meeting people's needs.

Formation of oil and natural gas

Decay of tiny marine organisms.

Major uses of fuels

Energy, transportation, production.

Location of majority of oil and natural gas in the U.S.

Texas, California, Alaska, Gulf of Mexico.

What makes an energy source renewable?

Continues being made.

Geothermal power plant energy production

Uses the earth's heat to create energy.

Geothermal heat pumps

Heat from earth heats water for homes.

Inadequate infrastructure relation to urban crisis

Infrastructure cannot support the city's population.

Well-managed rangeland characteristics

Good fencing, multiple water sources, maintenance of invasive species.

Ecological services definition and examples

What the environment provides for people; examples include forests, wind energy, and food.

Reducing effects of heat island

More land dedicated to preserving natural areas.

Ways to conserve energy at home

Solar panels, turning off lights, using low energy appliances.

Hydroelectric power plant electricity production

Water spins a turbine, turbine generates energy.

Coal power plant electricity production steps

Coal heats water, creates steam, steam spins turbines, turbines generate electricity.

Solar energy advantages and disadvantages

Advantages: free energy, renewable, low maintenance. Disadvantages: not aesthetically pleasing, upfront cost.
