Latitudes and longitudes and continents and oceans
Eastern Hemisphere is written as 70°E, and in the Western Hemisphere it is written as
65°W.
Longitudes tell us about the time. When the earth rotates on its axis, different
longitudes come before the sun. The longitude which is right before the sun has the
time of 12 o’clock noon. When the sun is right overhead above you, it is 12 o’clock at
your place.

Grid of Latitudes and Longitudes
When we draw longitudes and latitudes on the globe,
75º75º
they all intersect each other at right angles. This forms a 60º

grid. We can locate a place with the help of this grid. Prime 45º

Geographic Grid
globe : a model of the earth.
axis : an imaginary line joining the two poles through the earth.
latitude : an imaginary line lying parallel to the Equator.
longitude : an imaginary line joining the two poles along the earth’s surface.
heat zone : an area with a similar type of temperature.
grid : a network of latitudes and longitudes.
