Geography Lecture Notes Flashcards

Etymology and Fundamental Concepts of Geography

  • The term "geography" is derived from two root words that translate to "earth" and "written description."
  • Geography encompasses the study of environmental features and the tools used to understand them.
  • Cultural geography includes the examination of features and geographical tools.

The Five Themes of Geography

  • Location: This theme is categorized into two types: absolute and relative.
    • Absolute Location: This refers to the specific point where something is located on the surface of the Earth.
    • Relative Location: This describes the location of a place by comparing it to other places.
  • Place: This theme encompasses both physical and human characteristics.
    • Physical Characteristics: Natural features such as mountains, rivers, soils, and variety in plant and animal life.
    • Human Characteristics: Man-made elements including roads, buildings, agriculture, and industrial development.
  • Human-Environment Interaction: This theme explores how human populations adapt to their surroundings and how they modify their environment.
  • Movement: This refers to the relocation and transfer of people, goods, ideas, diseases, and other related phenomena.
  • Region: A region is defined by either formal boundaries or by specific functions that the area serves.

Geographical Tools and Measurement

  • The Globe: A globe is a tool that displays information about the surface of the Earth with perfect accuracy.
    • A typical globe is constructed using twelve strips of paper known as gores.
  • The Prime Meridian: This line of longitude passes through Greenwich, England, and is designated as the 00^{\circ} mark.
  • Lines of Longitude: These lines run in a north-to-south direction and are used to measure distances east to west.
  • Lines of Latitude: The equator serves as the center of these lines. They run in an east-to-west direction and are used to measure distances north to south.
  • Maps: Unlike globes, maps are generally flat. They are designed to show much greater detail and can cover vast areas.
  • Mental Maps: A mental map is an individual's personal perception of the world or specific parts of the world, based on the knowledge available to that person.

Map Projections and Distortions

  • Cylindrical Projection: The majority of world maps utilize some variation of the cylindrical projection.
  • Mercator Projection: Within a Mercator projection, all lines are represented as straight lines.
  • Goode’s Interrupted Projection: This projection has several popular variations, including specific map formats.
  • Robinson’s Projection: The most significant advantage of Robinson's projection is that it minimizes all four primary types of map distortions.
  • Azimuthal Projection: Also referred to as a planar projection, this method uses a flat plane for the map surface instead of a cylinder.
