For this exercise you will use the maps in Figure 2.5, 2.6, and 2.7 to make quantitative and qualitative observations about the spreading rate along the Mid-Atlantic Ridge. This is usually expressed in units of cm per year. The spreading rate of a mid-ocean ridge refers to how quickly it gets wider. Spreading Rates: How Fast Is the Atlantic Ocean Getting Wider? In this lab you will use a variety of maps and data sets to help you understand how we know where plate boundaries are on Earth, and how we know what types of boundaries are present. A printout of the worksheet for this lab is included in the EESC 111 lab package. These exercises make up your assignment for Lab 3.
