by Katie Durgin-Bruce, M.S.
What does the geography of your environment look like? Does it have mountains, cliffs, sandy beaches? Do you know how the rocks and soil beneath your feet formed? These were all formed by the slow rock cycle — changes that rocks go through as they move through the inside, and then to the surface of, the Earth. In this unit, you will learn about changes in the Earth — fast changes like volcanoes and earthquakes and slow ones like rain wearing away tiny bits of rocks. You’ll also learn about tectonic plates that form many of the big geographical features of the environment like mountain ranges.
