Mapping Earth
o Look at one place many scales and then try the zoom function in google earth.
o Now look at the same place many representations and see the different ways
maps can show information.
o Look at types of maps and then go to Exploring Maps to see different maps
developed by National Geographic.
o Look at mapping coordinates to refresh what you learned in geography about
latitude and longitude.
o Learn about Topography on Maps and then try the Topography gizmo to make
sure you understand it.
o If you want to look at topographic maps of areas you know.
o Take the quiz to make sure you understand today’s material.

Study Guide
SES1. Students will investigate the composition and formation of Earth systems, including the
Earth’s relationship to the solar system.
a. Describe the early evolution of the Earth and solar system, including the formation of
Earth’s solid layers (core, mantle, crust), the distribution of major elements, the
origin of internal heat sources, and the mechanism by which heat transfer drives plate
tectonics.
b. Explain how the composition of the Earth’s crust, mantle and core is determined and
compare it to that of other solar system objects.
