Vanishing Craters

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface. This activity helps learners understand how Earth's crust is constantly bombarded by weather which reshapes Earth's surface, erasing signs of craters that were originally made by rocky asteroids landing on Earth's surface.
