In the last lesson, you saw that rocks can form from different types of rock material. But how does that change occur? What processes form rock? In this lesson, you will use hard candy to model one of the processes that can form rock. You will then watch a video of a second process. You will apply what you learned by revisiting the rock hand samples you observed in Lesson 1.2. For homework, you will further explore how rocks formed in a particular setting—the beach.
