Our World- Land II

What is land made of? Soil, sand, pebbles and rocks. Rocks are a part of land, they can be different in many ways. Some rocks are too big to hold it in our hands. Some of them can be as big as a mountain. Other rocks are so small, we can hold thousands of them at once, thousands of grains of sand.
