A Grand Time!
Did you know that scientists believe the Earth is billions of years old? After years of conducting detailed research focusing on the Earth’s surface and its components, such as rock and fossil records, scientists are able to arrive at this claim. Yes, they studied rocks! Scientists have been able to uncover amazing details about our planet’s history by diving into the different rock layers that make up our planet. Amidst these layers, scientists are not only able to uncover the estimated age of our Earth, but they are also able to uncover Earth’s past environments by studying fossil evidence, as seen in certain rock types. In this lesson, students will interpret data that illustrates the various rock layers of our Earth to tell a story about Earth’s changing environments.
