Task: Geology-Volcanoes a) Crater lake – Convergent boundary b) Hawaii’s Kilauea – Intraplate boundary c) Mount St. Hellens – Divergent boundary d) East African Rift – Divergent boundarye) Yellowstone – Intraplate boundary f) Vesuvius – Intraplate boundaryg) Deccan Plateau –convergent boundaryh) Mount Etna – Intraplate boundary2. a) The diagram given is that of a strato volcano Reasons: -presence of steep upper slopes Presence of gentle lower slopes Presence of a small summit crater It is concave upwards.b) Stratovolcanoes are formed by large magma reservoir under the surface of the earth gets built over a long period of time forming hilly structure that later develops into a mountain.
The magma of this type of volcano is usually produced at a relatively slower rate by the process, thus tending to be thicker or viscous, holding more pressure and gas. The pressure and gas normally build over a long period of time. The contents of the magma include SO2, CO2, H2O, and Cl2. c) Subduction zoned) Washington D.C. (Mount St Helens)3. a) The lava is from molten magma formed due to rocks melting from below. b) The source rock melts because of the high temperature and pressure underground.c) Divergent boundaries that result into the formation of volcanic islands.
Tectonic plates move apart thus producing gaps where molten lava rise to fill. I would expect solidified lava. 4. The places where the activities take place are referred to as hot spot volcanoes. In these places, a large plume of magma from the underground magma arise and end up in the crust erupting its lava onto the earth’s surface over a long period of time building a volcano, which is usually basaltic in nature. Magma plumes also do occur at the convergent or subduction boundaries that are generated due to the melting of the subducting plate due to intense pressure and heat.
The magma arises onto the crust forming a volcanic mountain. 5. a) Intraplate zoneb) Divergent zonec) Divergent zoned) Subduction zone (d) will develop explosive eruptions. (a) will produce outpouring basaltic lava. Work CitedChallen, Paul. Volcano alert! London: Crabtree Publishing Company, 2004. Print. Fullager, Paul & West, Nancy. Project Earth Science: Geology.
