This week students are continuing their ride along Earth’s bumper cars. Students will learn that the Earth is under stress just like HUMANS are. Students can really relate because many of them had stress coming up to present during their VOLCANO projects. The Earth’s crust undergoes Tension, Compression, and Shearing. Stress puts pressure of the Earth’s crust which causes faults. Faults are a break in the Earth’s crust. The three types of faults are a normal fault, a reverse fault and a strike-slip fault. Students have already learned that the 3 types of boundaries are convergent, divergent, and transform boundaries so making the connection to boundaries creating faults should be an easy one. By the end of th week students will make the connection that the stress of compression happens at a convergent boundary which causes a reverse fault. The stress of tension happens at a divergent boundary which causes a normal fault. In these instances the earth’s crust will lift or fall. Shearing happens at a transform boundary and causes a strike-slip fault which causes the Earth’s plates to slide past each other.
