Lets Begin the adventure...

Direction
  • Direction is the point towards which you are
    looking or moving.
  • The cardinal directions of the compass are
    north, south, east and west.

3
Intermediate Points
  • Northeast, northwest, southeast and southwest are
    known as intermediate points.

4
Magnetic Compass
  • It is a more reliable method of determining
    direction.
  • Its needle points to the magnetic north pole.
  • It is divided into 360 parts called degrees ().
  • The degrees are numbered in a clockwise direction
    starting from north (0).

5
Maps Atlases
  • A map represents a part of the real surface of
    the Earth.
  • An atlas is a reference book containing many
    maps.
  • Symbols and colors are used to show the main
    features on a map.
  • A legend (key) of the map is used to interpret
    unknown symbols.

6
  • A symbol is something that represents or stands
    for something else.
  • Mapmakers tend to use the same system of symbols
    on all maps they make.
  • These are called conventional symbols.

G.P.S. (Global Positioning System)
The GPS is a system of 24 satellites that all
work together to create an exact view of Earth.
Using advanced technology, these satellites
compare one location to a grid of numbers and
then find a location, to a great degree of
accuracy!
8
Atlas Maps of Various Types
  • Physical maps show the shapes of the landmasses
    and water bodies.
  • They use a system of colors to indicate the
    height of the land surface.

9
  1. Political maps show the countries, their
    provinces, and the main cities.

10
  1. Theme maps provide information about specific
    topics such as population, climate, and resources.

How can we describe the exact location of a
specific place on Earth?
  • Lines of latitude
  • They are also known as parallels.
  • They run horizontally.
  • The equator is 0 Latitude.
  • The equator is the line that divides the Earth
    into two hemispheres the North Hemisphere and
    the Southern Hemisphere.

13
  • Latitude is measured from 0 to 90N in the
    Northern Hemisphere and 0 to 90S in the
    Southern Hemisphere.

14
  • Lines of longitude
  • They are also called Meridians
  • These lines run vertically.
  • These vertical lines form half-circles connecting
    the North and South Poles.
  • The prime meridian is 0 longitude and divides
    the globe into two hemispheres the western
    hemisphere and the eastern hemisphere.
  • There are 180 of east longitude and 180 of west
    longitude.

15
  • If we combine the lines of latitude and longitude
    we get a grid (a network of intersecting lines).
  • These intersecting lines are coordinates
    (intersecting lines) was developed to locate
    places with precision on the surface of the
    globe.
