Facts

• A globe is a model to study the earth.
• The earth rotates on an imaginary line called axis.
• The latitudes are imaginary horizontal lines running parallel to the Equator.

• The North Pole and the South Pole are the extreme points which the axis touches.
• The most important latitudes are the Equator, tropics, circles and poles.
• The longitudes are imaginary vertical lines joining the two poles.

• Latitudes and longitudes are marked in degrees.
• Latitudes and longitudes form a grid which helps us locate a place on the globe.
