• Learning Task 2: Restate the cause and effect of an earthquake fromthe given informational text below. Do this in your notebook.Why do Earthquakes happen?Earthquakes usually happen when underground rocks suddenlybreaks along a fault. This sudden release of energy causes the seismicwaves that make the ground shake. When two blocks of rock or twoplates are rubbing against each other, they stick a little. They do notjust slide smoothly; the rocks catch on each other. The rocks are stillpushing against each other, but not moving. After a while, the rocksbreak because of all the pressure that was built up. When rocks break,an earthquake occurs. During and after an earthquake, the plates orblocks of rocks start moving, and they continue to move until they getstuck again. The spot underground where the rock breaks is calledthe focus of the earthquake. The place right above the focus (on topof the ground) is called the epicenter of an earthquake.Source: http://www.geo.mtu.edu/UPSeis/why.htmlCause #1Effect #1===Cause #2Effect #2Cause #3Effect #3​
