Prime MeridianPrime Meridian Meridian refers to the

lines of longitude that go north and south.

The Prime Meridian is a imaginary line that is defined as 0°. The opposite to the prime meridian is the international date line which is located at 180°.

Meridian refers to the lines of longitude that go north and south.

The Prime Meridian is a imaginary line that is defined as 0°. The opposite to the prime meridian is the international date line which is located at 180°.

International Date Line - International Date Line - The International

Date Line (180°)- is an imaginary line on the surface of the Earth opposite the Prime Meridian which offsets the date as one travels east or west

What is a map?What is a map?•What information can a map tell us?

•What is an Atlas?

A map is a representation of the partial surface of the earth.

• Maps usually represent information in 3 ways:

Using color

Using symbols

Using words

What do these two maps tell us?

What symbols are they using?

What important things are they missing?

Why are these two maps better than the last two? What have they included?

What is a legend?What is a legend?• A legend explains the meaning of symbols on a map.

•It is usually located beside the map near the bottom of the map. The legend is not located at the top of the map.

•Some maps call a legend a key, but for the purpose of this class we will call it a legend.

What are some symbols that are used in a map?

All good maps include a: Title, legend, and a compass rose.

What is a compass rose: An illustration on a map or chart that shows the different points of direction (North, South, East, West and Intermediate directions: Northeast, Southeast, Southwest, and Northwest).
