How Do Map Projections Distort Earth's Surface?

How Do Map Projections Distort Earth's Surface?

This site, part of Exploring Earth Investigation by McDougal Littell and TERC, examines how map projects distort Earth's surface. The investigations "were designed to build students' knowledge of Earth Science concepts�and to raise student awareness of Earth as a system of interconnected components and processes." On the site, visitors will find information on representing the spherical Earth on a flat map, the different common projections used, and how to measure the properties of the projections. Many sections contain interactive features and questions which allow students to investigate and understand the ways that flattening the Earth creates problems with maps and what cartographers have done to minimize the distortion. This is an excellent site for any Earth Science classroom as an introductory lecture or out-of-class exploration.
