Earthquakes are formed as a result of tectonic movement in the earth’s crust. The magnitude of an earthquake is directly proportional to how dangerous it is and the damage it will result in. During our science classes we were able to understand how they occur. Just how much did you understand about earthquakes? Take up this test and find out!
