Have you ever seen a mushroom-shaped rock?

This lesson has 2 geology history mysteries for you to explore. First, you’ll learn about the different conditions that determine whether a canyon or a v-shaped valley is more likely to form. Then, you’ll learn about the mushroom-shaped rocks called earth pillars (or hoodoos). After all that talk about erosion, you’ll get to do a sorting activity to learn about the differences between weathering, erosion, and deposition.
