### latitudes and longitudes

LESSON 3 and 4: LATITUDES

• DEFINITION: Latitudes are imaginary lines running from west to east on the earth surface.
• Latitudes are numbered in degree (°) North and South of the equator.
• The latitude 0° is the longest latitude and divides the earth into two equal halves called HEMISPHERE the north hemisphere and the southern hemisphere
• There are 90 latitudes in each hemisphere
• Latitude 90° north is the north pole and latitude 90° south is the south pole

CHARACTERISTICS OF LATITUDES

• They are parallel lines that do not meet
• They run from west to east
• The highest latitudes is 0°
• They get shorter moving from the equator to the poles
• Only the equator is a great circle
• Each latitude is separated from the other by an equal distance of 111km

LESSON 4: LONGITUDES

Definition: Longitudes are imaginary lines running across the surface of the earth from North Pole to South Pole. They are also called MERIDIANS

IDENTIFICATION

• The first meridian is the 0° is known as the GREEN WHICH MERIDIAN or the PRIME MERIDIAN
• All longitudes are numbered to the west and the east of the green which meridian

Characteristics

• They meet at the poles
• They run from north to south pole
• They are of equal length
• The highest longitude is 180°
• All longitudes are great circles
