Select the Global Paleogeographic Model folder. Double click to zoom out. Also select the placemark labeled “Question 30” and navigate to where it is in view. Toggle through the beginning of the Permian (~300 Mya) through its end (~250 Mya). What significant event happens at the placemark during this time?Tip: Check out Figure 11.11 in your book to help orient where the modern continents were at this time as you explore the model on Google Earth Pro. Mark all that apply.

We can extract the zircons from these rocks to obtain an age of the zircons, thereby providing the age of the first preserved material on Earth.Within the zircons in this rock sample, the ratio of parent to daughter isotopes is 8.5:7.5. Using the chart below, determine how many half lives have passed.

Check the box next to “Mona Formation, Michigan”. Double click to fly there. Click on the placemark to view the sample taken from this location. This Archean metamorphosed basalt (aka “greenstone”), dated~4.0 Ga, was collected from an outcrop revealing another area of the Canadian shield in Michigan.Based on what you know about basaltic igneous environments, proto continent formation, and types of metamorphism, order the likely events of this time in Earth’s history.Tip: Review figure 11.2 in your book
