Western Sahara Geography Stats

Definitions

  • Area > Comparative: The area of various small countries expressed in comparison to various areas within the United States of America.
  • Area > Land: Total land area in square kilometres
  • Area > Total: Total area in square kilometers
  • Area > Water: Total water area in square kilometers
  • Climate: A brief description of typical weather regimes throughout the year.
  • Coastline: The total length of the boundary between the land area (including islands) and the sea.
  • Elevation extremes > Highest point: Highest point above sea level
  • Elevation extremes > Lowest point: This entry is derived from Geography > Elevation extremes, which includes both the highest point and the lowest point.
  • Environment > Current issues: This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry:
    Acidification - the lowering of soil and water pH due to acid precipitation and deposition usually through precipitation; this process disrupts ecosystem nutrient flows and may kill freshwater fish and plants dependent on more neutral or alkaline conditions (see acid rain).
    Acid rain - characterized as containing harmful levels of sulfur dioxide or nitrogen oxide; acid rain is damaging and potentially deadly to the earth's fragile ecosystems; acidity is measured using the pH scale where 7 is neutral, values greater than 7 are considered alkaline, and values below 5.6 are considered acid precipitation; note - a pH of 2.4 (the acidity of vinegar) has been measured in rainfall in New England.
    Aerosol - a collection of airborne particles dispersed in a gas, smoke, or fog.
    Afforestation - converting a bare or agricultural space by planting trees and plants; reforestation involves replanting trees on areas that have been cut or destroyed by fire.
    Asbestos - a naturally occurring soft fibrous mineral commonly used in fireproofing materials and considered to be highly carcinogenic in particulate form.
    Biodiversity - also biological diversity; the relative number of species, diverse in form and function, at the genetic, organism, community, and ecosystem level; loss of biodiversity reduces an ecosystem's ability to recover from natural or man-induced disruption.
    Bio-indicators - a plant or animal species whose presence, abundance, and health reveal the general condition of its habitat.
    Biomass - the total weight or volume of living matter in a given area or volume.
    Carbon cycle - the term used to describe the exchange of carbon (in various forms, e.g., as carbon dioxide) between the atmosphere, ocean, terrestrial biosphere, and geological deposits.
    Catchments - assemblages used to capture and retain rainwater and runoff; an important water management technique in areas with limited freshwater resources, such as Gibraltar.
    DDT (dichloro-diphenyl-trichloro-ethane) - a colorless, odorless insecticide that has toxic effects on most animals; the use of DDT was banned in the US in 1972.
    Defoliants - chemicals which cause plants to lose their leaves artificially; often used in agricultural practices for weed control, and may have detrimental impacts on human and ecosystem health.
    Deforestation - ...
    Full definition
  • Note: This entry includes miscellaneous geographic information of significance not included elsewhere.
  • Land boundaries > Border countries: Length of land boundaries by border country
  • Land boundaries > Total: The total length of all land boundaries and the individual lengths for each of the contiguous border countries
  • Land use > Arable land: The percentage of used land that is arable. Arable land is land cultivated for crops that are replanted after each harvest like wheat, maize, and rice
  • Land use > Permanent crops: The percentage share of used land on which permanent crops are grown. This is land cultivated for crops that are not replanted after each harvest like citrus, coffee, and rubber. It includes land under flowering shrubs, fruit trees, nut trees, and vines, but excludes land under trees grown for wood or timber.
  • Natural resources: A country's mineral, petroleum, hydropower, and other resources of commercial importance.
