Our first report from last week (10/31-11/4) comes from Christie Webb. Christie writes:
This week was interesting! Monday Mr. Kite talked about the different types of volcanoes and the magma each volcano holds. For instance shield volcanoes are the biggest volcanoes. But they ooze out and hardly do any damage. He talked about earthquakes which are caused by plates moving around each other and they get stuck and the stress builds on the plate and the plate then slips. Where it slips is called the fault line (where the earthquake first started.) we also learned that we have three different types of faults, Reverse Fault, Normal Fault, and Strike-Slip Fault. On Wednesday we did a very interesting experiment. In this experiment we used dish detergent and we added 25mL of salt. As we inserted the salt we then noticed that the detergent got thicker meaning as more rock melted then the faster the lava moves to push the plates that causes volcanoes to erupt and plates to slip. In conclusion, this week we learned how a volcano is made, how an earthquake happens, and why it happens.
