Mars Fluvial Channels: Contour Maps

Homework 1- Surface Water_MFE

Julia Kahmann-Robinson PhD, University of Utah Department of Geology & Geophysics

Purpose

Students will become familiar with contour maps in general and how to read them. Observe fluvial incised-channels on a contour map of Earth and compare to a contour map of Mars, making predictions of potential fluvial activity on Mars.

Preparation

  1. If not uploaded to you or your student's Google Earth application, load the USGS topographic maps layer to Google Earth using the following website and link: http://www.gelib.com/ng-topo.htm
  2. Print a classroom set of the Mars contour map* found here: http://pubs.usgs.gov/imap/i2782/i2782_sh2.pdf . Students may also navigate to the contour map online and accomplish the homework similarly.

*Beware, the download time for this map can be slow, especially if you have a slow connection.

Directions/Questions

1. To get your bearings on Earth, Center your map/viewer on the following coordinates: 38°27'N, 109°41'W, near Pyramid Butte, UT






2. Using the Mars contour map (*beware, the download time for this map can be slow, especially if you have a slow connection) find Valles Marineris. Look northeast of Valles Marineris, around the 330E/30W longitude line and the Martian equator.
