The diagram shows the movement of the Pacific and North American plates along the San Andreas fault located in California. Why do earthquakes occur near the San Andreas fault?

Roger poured water over a pile of sand. Some of the sand washed away. This process is similar to which of the following?

Rafael lives near a road at the bottom of a hill. His parents are concerned that soil will wash off the hill and rocks will fall onto the road. Rafael conducts an investigation to find out if grass growing on a hillside will help stop soil erosion. He collects two samples of the same size and type of soil. One sample of soil has grass growing on it and the other does not. He places each sample of soil in a small tray. For his investigation, Rafael pours the same amount of water onto both samples of soil. He uses a large tray to collect water that may flow through the soil. Which practice shows the best way for Rafael to set up his investigation?

After pouring the water onto both pieces of soil, Rafael makes an observation. The water collected in the tray under the soil with grass looks clearer than the water collected in the tray under the soil without grass. What conclusion can Rafael make from his observation?

Which layer of Earth is divided into plates?

Three funnels were filled with equal volumes of pebbles, fine sand, and coarse sand, as shown in the diagram. The same amount of water was poured into each funnel. Which correctly lists the order in which the water passed through the funnels, from fastest to slowest?
