Globe: three-dimensional model of the Earth’s surface. *A globe is the best model of Earth, because is correctly shows the shapes and sizes of features on Earth Map

What Are Maps?

Objective: Explain why a globe is the most useful type of Earth map. Describe what happens when the round Earth is shown on a flat map

Map: flat model of Earth’s surface. The earliest known maps are more than 4000 years old, and were carved on clay tablets. They were used to record property lines and help build roads, canals, and towns.

Distortion: error in shape, size, or distance. Almost all maps have distortions, because it is difficult to copy large areas onto smaller models

Things that maps show:

* Some show locations of and distances between places on Earth

* Others show city streets

* Some show buildings in town

* Some show weather or types of soil in an area

1.5 Notes

What is a map projection?

Objective: Explain what a map projection is. Name the three kinds of map projections

Map makers take a plastic globe with a light inside. They trace the outlines of the continents onto paper in order to make a flat map from a round globe
