10.1 Land use
T/F: Cities must EXPORT almost all of the resources used by their residents
False, import
T/F: The ecological footprints of cities are SMALLER than their actual land areas
False, larger
T/F: The env. and health impacts of pollution are shared EVENLY among urban residents
False, unevenly
How did Industrial Revolution affect urbanization?
Farms produced surplus food, which allowed farmers to stop farming and move to cities. Technological advancements created job opportunities.
Land use
Human activities that occur on land directly related to the land
Why does Urbanization occur?
Better Jobs Growing population More people move from country to cities than vice versa
Where does Urbanization Occur
Cities near waterways, railroads, and highways. (moderate climate and central geography)
Positive Impacts of Urbanization
Efficiency/ fuel reduction Land preservation Economic
T/F: The poor typically live UPSTREAM from polluting factories
False, downstream
How are Land use and Land cover DIFFERENT?
Land cover is whats on top of land Land use is HUMAN ACTIVITY on land.
Relate the high population density of cities to the efficiency with which resources can be distributed within the city
Less fossil fuel is needed to deliver resources and goods to people living close together than to sparsely populated areas
Relate high density in cities to efficient distribution of resources.
Less fossil fuels are used to transport goods because people live closer together.
Is US becoming more or less urban over time?
MORE. Today, US is 80% urban In 1950, 65% was urban
What factors would promote growth of town into a large city?
Moderate Climate Central Geography Ease of transportation (located near water or highway or railraod)
Negative Impacts of Urbanization
Pollution Heat Islands Imported Resources Ecological Footprint
Explain how land cover is related to land use
They are similar because what covers the land, dictates what the land can be used for.
How can a city's infrastructure lead to the formation of a heat island
They can generate heat and trap more heat. Roads and buildings can also generate more heat.
Urbanization
This shift of population from the countryside to urban areas
What area of land cover would you most likely expect to find the highest human population
Urban areas
Urban VS Rural
Urban: More people. Rural: Farming, recreation, preservation of nature
How are Land use and Land cover SIMILAR?
Whatever covers land dictates what land can be used for.
Does land cover change as people settle into an area?
YES
heat island
an an area in which the temperature is several degrees higher than that of the surrounding area
How do scientists assess changes in land cover and land use
by studying how much its changed and damage or reconstruction done
LIGHT POLLUTION
describes the way that city lights brighten the night sky, obscuring the stars and planets
Rural area
generally any other type of land use or land cover thats not classified as a city or urban
List three examples of land cover types that the US Geological Survey researches
grass, trees, water, ground, etc.
Urban area
mostly developed land covered mainly with buildings and roads that has a human population of 2500 or more.
the vast grasslands that once covered the middle of North America have mainly been replaced by
rangeland and cropland
Land cover
refers to the vegetation and manufactured structures that cover land.
Infrastructure
the facilities, services, and installations necessary for the functioning of a community
Cities and suburbs are examples of
urban areas
