1. Scientist studying plate tectonics compiled the chart below showing the distance that the North American continent moves from year to year. Based on this information how far will the continent have moved from the first measurement in the year 2001? 10.4 cm 15.6 cm 20.8 cm 26.0 cm Year Distance Moved from 1st Measurement 1998 5.2 1999 10.4 2000 15.6 2001 ?

5. Read the selection below 5. Read the selection below. Circle the answer that correctly completes each statement. Rocks are all around us. They form the crust of the Earth. People use rocks for many things. They climb them, collect them, wear them, and build things with them. Rocks change. They break down, melt, change shapes, harden, and soften. Rocks are found in three forms: igneous, sedimentary, and metamorphic. Igneous rocks are formed when red-hot melted rock cools down. Melted rock or magma comes from below earth’s surface and flows from volcanoes and is then called lava. Granite is one type of igneous rock. Sedimentary rocks are formed when tiny bits, called sediments, are washed away by rain and snow. The sediments settle in streams and river beds, as well as on the ocean floor. Over a long period of time the sediment hardens to form rock. An example of sedimentary rock is sandstone. Sometimes rocks get buried deep inside the earth. These buried rocks could be any type: igneous, metamorphic, or sedimentary. The heat and pressure deep within the earth change the rocks that are buried there. Rocks that have been changed from one form to another are called metamorphic. Slate is a metamorphic rock.
