Rocks and Soils Assessment Study Guide

Plants need soil to grow. The roots of the plants grow down into the soil to hold the plant in place. The property of soil that tells us whether or not a soil is good for growing plants is the texture. If the texture is grainy, like sand, the roots will not be able to hold the plant in place. If the texture is too thick and hard, the roots will not be able to grow deep enough to hold the plant in place.

Which location would have the best soil texture for plants to grow?

• on the beach

• near a creek

• on a rock

• in the desert
