Transcript of Mount Nyiragongo

Mount Nyriagongo Mount Nyriagongo's last known eruption was back in Monday February 25, 2002. Latitude: 1.52°S 1°31'0"S

Longitude: 29.25°E 29°15'0"E Mount Nyriagongo is located in the DR Congo in Africia. Only 45 estimated dead
during it's last eruption. Mount Nyiragongo is one of the worlds most active volcanoes. ~ 1.2 km diameter ~ Worlds largest and most active lava lake ~ Virunga national park ~ 820 feet deep ~ Stratovolcano ~ Known for devastating eruptions ~ 11,380 feet above the ground at the rim ~ One of the least studied ~ Most active of the eight volcanoes forming the Virunga range Layers of the Earth. Crust, mantle, outer core, inner core.
Crust is the top of the earth (part we walk on). Mantle is under the crust, more denser than the crust, biggest layer of earth. Outer core is liquid, magma, more denser than mantle, and is hot really hot. Inner core is solid, the most dense of all the layers. Hot spots form to make volcanoes, P-waves move through solid and liquid, S-waves move through solids. The Rock Cycle Igneous Rocks: Come from magma. Intrusive, cools under ground. Extrusive, cools above ground. Black and has spots.
Metamorphic Rocks: Change into other types of rocks. Foliated, has swirls. Nonfoliated, no swirls. Mostly white.
Sedimentary Rocks: Layered rocks, has sediments in layers. Earthquakes, good or bad. A earthquake is a release of tension in a rock. Primary and Secondary waves - P-waves travel through both solid and liquid.S-waves travel through only solids. Earthquakes can cause the plates to move which can cause hot spots to move and eventually new volcanoes can form, plus the hot spot can cause volcanoes that are not active to become active. Use a seismograph to measure the epicenter of earthquake. Triangulation is also used to find the epicenter. South Carolina's Geologic History SC is made up of Blue Ridge, Piedmont, Sandhills, Coastal plain, and Coastal zone. Blue Ridge: smallest, the mountain region of SC. Piedmont: foothill region of SC. Sandhills: used to be an ancient beach, only 10 miles wide. Coastal plain: land is flat, 2/3 of SC, ancient fish fossils. Coastal zone: coastal line on SC, Grand strand, Santee delta, Sea island complex. Union is located in the Piedmont. Union is also on a fault line. http://www.volcano.si.edu/world/volcano.cfm?vnum=0203-03=
