Introduction

You have been asked to choose the type of sand for the new playground. Your job is to learn about sand and the many different kinds of sand and pick one for the playground.

First let's review.

When we looked at sand with our hand lens, it looked like little rocks. Sand is known as sediment. Gravel, silt, and clay are sediment. These earth materials are made by the breaking down of rock. These materials are moved by wind, water, or ice. They end up in rivers, or lakes, as sand dunes, or sediment in the sea. In the end this material gets buried deep enough to harden and form sedimentary rock.
