LAB 7: TOPOGRAPHIC MAPS
Due: Monday, April 11
PART I: CONTOURING AND PROFILES (20 PTS)
1. Contour this area map using a 5 meter contour interval. Remember some fundamental rules of contour
lines, as well as some important characteristics of rivers.

12.001 Introduction to Geology
In these lectures we investigate some ways in which organisms assemble them
selves into an ecosystem.
We address two types of questions:
Geometry. How can we characterize the topological assemblyi.e., the

We have spoken of volcanism as the long-term source of CO2 .
Among the other sources, the respiration ux is about 3 orders of magnitude
