Longitude and Latitude
Transcript of Longitude and Latitude
The earth is broken into halves vertically and horizontally. The imaginary lines are used by people to divide the earth into different sections, called hemispheres. Hemi- means "half" and sphere means "globe."
What is a Hemisphere?
The Earth is divided into imaginary halves
Think of a Cartesian Plane in Math but, instead of using negative and positive numbers, we use degrees and the 4 cardinal points
Hemispheres in Math
Latitude lines are imaginary lines on the earth's surface. They run east and west around the globe and tell you your distance north or south of the Equator.
Latitude lines run east and west, but they tell how far up (north) you can go or how far down (south) you can go.
Latitude lines are parallels, which means they are always the same distance apart and never meet.
The First Latitude Line
Longitude lines are imaginary lines on the earth's surface that run from pole to pole around the globe and tell you your distance east or west from the Prime Meridian.
Longitude lines run north and south, but they tell how far east you can go or how far west you can go.
