Document Summary
The landforms across this continental expanse influence the movement and interaction of air masses and contribute to its enormous climate variety. Many dams and reservoirs for irrigation projects have been built to make agriculture possible. Because of the low level of rainfall, however, the amount of water that is being extracted exceeds the capacity of ancient underground water basin (aquifers) to replenish themselves. Generally, central north america is wettest in the eastern and southern parts and driest in the west and north. The large size of the north american continent creates wide temperature variations. On a per capita basis, north americans contribute among the largest amounts of greenhouse gases to earth"s atmosphere. One of these is north america"s dominant pattern of urbanization, characterized by vast and still growing suburbs where automobiles are the main mode of transportation. North american industrial and agricultural production also depends very heavily on fossil fuels.
