One way to begin this activity is with the following narration: “This is a cartoon of an outcrop of 300-million year old rocks found in West Virginia. The little “smiley faces” are fossils (brachiopods in this case), the dots are sand grains of various sizes, the brick pattern is limestone, a partial brick pattern indicates the rock is only partly limestone, the thick horizontal solid black line is coal, and the little vertical squiggles sticking out below the coal are plant roots. (Does this help you figure out which way is up?) Dashed lines of different sizes represent lack of artistic talent—they should all be the same length? Don’t forget to note the differences in the way the various rocks touch each other (contacts). Some are well defined, others are less well defined, while some are actually not even perfectly horizontal. The number of fossils is not the same everywhere. The size of the sand particles shows a fairly consistent change vertically. Not all of the rock layers are continuous. To a geologist, these little clues provide insight into what happened long ago.. Rocks are classified by how they are formed, their composition, and texture. Rocks change over time through the rock cycle. TYPES OF ROCKS. ROCKS ARE DIVIDED INTO THREE GROUPS BASED ON HOW THE ROCKS . Hill Science 6. Earth Processes. DO NOW . 1. What type of rock is created when molten rock cools and hardens?. 2. What type of rock is created when existing rock is changed by heat and pressure?. 3. What type of rock is created when rock is weathered, eroded, deposited, compacted and cemented?. 2. Major Rock Groups. Igneous. Formed from . molten rock (magma/lava) that has cooled. Literally means “from fire”. 1.
