ROCKS AND MINERALS

We have learned that rocks are made of minerals and that scientists test the rock's physical properties like color, luster, hardness and streak to identify the minerals in them. We also learned that there are three different types of rocks according to the way in which they form.  Watch the following video about different types of rock in U.K. (England), then answer some questions using the information in the video.
