1. VOLCANOES and EARTHQUAKES By Patrick Taylor Ms. Armstrong's 3rd period class

2. Mandatory questions ● 2. The ring of fire is located in the pacific ocean. I found this on page 83 of the textbook. It is called the ring of fire because, it is made of active volcanoes that are in the shape of a ring. I found this on page 83 of the textbook. ● 1. Earthquakes happen when the energy of 2 tectonic plates is released. The energy then causes vibrations that cause earthquakes. Earthquakes form on fault lines. I found this on http://www.eduplace.com/kids/sla/6 /volcanoes.html. Volcanoes form when hot magma from the mantle rises to the surface, then as the hot lava cools and the ash builds up the volcano grows. Volcanoes also form on fault lines. I found this on http://weatherization/weather- volcano.htm. ● 3. Earthquakes are measured with different kinds of scales are used the most famous is the Richter scale. I found this on page 54 in the textbook. we measure earthquakes because, it helps us keep record of the strongest earthquakes and helps certain areas stay pepared for earthquakes. I found this on pages 68-72 in the textbook.

3. Chosen questions 3A. An area with lots of earthquakes is Alaska It has the most earthquakes of all states, it has three of the worlds top ten earthquakes. It has the second highest earthquake a 9.2 on the Richter scale. It has 24,ooo earthquakes a year. Every 13 years on average Alaska has a 8.0 magnitude earthquake or higher. I found this on http://www.alaskakids.org/index.cfm/know- alaska/Alaska-Geography/Earthquakes. The things that Alaska has done for safety is they made all of their new buildings bolted to concrete supports, and are tring to make everything bolted down. They have also tought almost every Alaskan how to hide under a desk or table. I found this on http://www.aeic.alaska.edu/html_docs/pdf_files/eqprepar e.pdf. ● 4B. Earthquakes are measured because, it allows us to be prepared for some earthquakes in areas where there has been previous history of earthquakes. I found this on page 68-72 in the textbook.

4. Student made questions 1. Earthquakes happen very often. There is always an earthquake happening at all times of day, but most are to weak to be felt. i found this on http://www.earthquakescan ada.nrcan.gc.ca/info- gen/magfreq-eng.php. ● 2. The average amount of volcanic eruptions per month is, 50-60 eruptions a month on average. I found this on http://www.scholastic.com/teach ers/article/volcanic-eruptions. ● 3. The advantages of living near a volcano are the volcano produces geothermal power, all of the ass may be harmful at first but then makes fertile soil and, living near one allows you to study it easier.
