Place we live in EARHH

• Lithosphere


  Ranges the crust and upper mantle
• Asthenosphere


  Thin, flows very slowly as if the crust is sliding upon it
• Earth's layers


  • Crust
  • Mantle
  • Outer core
  • Inner core
• Crust


  • 10km thick, made of basalt
• Mantle

  • 2900km thick, makes up 2/3 of planet's mass
• Core


  • 3500km thick, made of iron and nickel
• Mesosphere


  Means "middle sphere"
• Outer core


  Made of dense magma
• Inner core


  Solid, makes up third of planet's mass
• Globe


  • Difficult to replicate and modify, shows international and mathematical details (timezones, borders, distance)
• Map


  • Often specific to domestic territories, portable, shows efficient mainland roads, shows specific landmarks, can show relationship between local phenomena
• Types of maps


  • Political map
  • Physical map
  • Topographic map
  • Climate map
  • Economic map
  • Road map
  • Thematic map
• Political map


  Shows boundaries between regions and respective municipalities nationwide depending on the degree of detail upon the map
• Physical map


  Highlights locations with large bodies of water and to show differences in terrain through streaks of colors when planning to set a course across the wilderness
• Topographic map


  Shows differences in elevation throughout terrain via contour lines that allows one to visually calculate the steepness of slopes along a certain path
• Climate map


  Shows frequently observed climate activity within a certain area and details about the intensity of certain weather patterns
• Economic map


  Shows estimation of accessible natural resources and existing industries within a given area through symbols and graphic representations
• Road map


  Shows points of interest and landmarks for easier navigation and areas predicted to have high activity. In such maps, major highways are often in red while minor roads are in lighter colors and are narrower
• Thematic map


  Details put into such maps can encompass most of the previously described map types or may instead present certain specific findings about a given area
• The Earth shows its uniqueness through its many features, among which is the liquid water on its surface & an atmosphere that contains a significant %tage to oxygen
• It has one natural satellite, the Moon.
• Earth's axis of rotation is tilted with respect to its orbit around the sun.
• The earth is divided into two hemispheres; Northern Hemisphere & Southern Hemisphere
• The Earth is divided into two hemispheres by the equator, with the Northern Hemisphere being warmer than the Southern Hemisphere due to the angle of incidence of sunlight.
