Activity 2 Calculating Seafloor Spreading Rates from Paleomagnetic Data 1. Look at Figure 1 (figures are at the end). There are three lithospheric plates on the map: Pacific plate, Cocos plate, and Nazca plate. The black double lines shown in the diagram indicate the East Pacific Rise (EPR). The colored areas represent the paleomagnetic anomalies ("stripes"). The ages of these anomalies are shown in the key at the top of the diagram, and a scale of 500 kilometers is shown at the bottom of the diagram. 2. With your ruler, measure and record the length of the 500-km scale in centimeters below in question 7.
