Volcano Mapping Activity The early Earth was completely molten but over many millions of years the crust we now live on cooled into the land we now live on. Beneath the crust we live on is a ‘plastic’ mantle of very hot rock. This rock can be squeezed towards the surface and then turns into melted rock called magma, when underground, and lava, when above ground. When this lava comes out of the ground a volcano is born. Volcanoes do not occur randomly around the Earth. The majority of volcanoes are found where two pieces or plates of the Earth’s crust meet. When we look at the locations of volcanoes around the Earth patterns emerge. Below is a list of areas with large numbers of active volcanoes. Create a Google sheet of these volcanoes in your district Google Drive with one column for the Volcano name and one column for the Location. Title the sheet Volcano Mapping Data. Volcano Location Irazu Pacayas, Costa Rica Koryakskaya Yelizovo, Russia Kliuchevskoi volcano Kamchatka, Russia Lassen Peak Shingletown, California Misti, Peru Charcani Grande, Peru Mt. St. Helens Mt. St. Helens, Washington Osorno Osorno, Chile Paracutin Zirosta, Mexico Pogromni Pogromni, Aleutian Islands Sangay, Ecuador Chambo, Ecuador Santa Maria Loma Linda, Guatemala Ruapehu Ruapehu, New Zealand Taal Luzon, Phillipines Duncan Canal Wrangell, Alaska Mt. Pinatubo Luzon, Phillipines Tambora Tambora, Indonesia Mt. Fuji Honshu, Japan Zavaritzki Caldera Simushir Island Simbo Solomon Islands Fueguino Isla Darwin, Chile Once your Google sheet is created watch this video and follow the directions: http://www.sausd.us/cms/lib5/CA01000471/Centricity/Domain/1837//Ea rth Science/Using Google Maps for Volcanoes.mp4 Now that you have created your map, add some interest by including some pictures. Watch this video for instructions: http://www.sausd.us/cms/lib5/CA01000471/Centricity/Domain/1837//Ea rth Science/Adding pictures to your map.mp4 Finally, add a link (the url) to your map on this form: https://docs.google.com/a/sausd.us/forms/d/1af0v2bUVibAw9TWNu7ii TiZZtwMD8psmTaRS-KemWXs/viewform?usp=send_form or http://goo.gl/forms/PaMluMv6Nh Make sure you have shared your map with Mr. Richardson at [email protected] Summary: Look at your map and the locations of the volcanoes you have located. Describe any pattern you see. Are the volcanoes scattered evenly? Do a web search for ‘patterns of volcano distribution’ and see if you can identify and describe a pattern. ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________
