EES Exam 2 Questions and answers. Latest Update. Verified. Is all volcanic activity violent and explosive? - -No What is magma? - -Melted rock material How does magma vary? - -It varies in composition. Some can have more silica than others. Silica content - -Silica makes magma more viscous because silica tetrahedra link together. Gas content - -Different dissolved gases, such as H2O and CO2, can control how a volcano erupts. What is the difference between rhyolitic and basalt...

One process that occurs only at convergent plate boundaries - Answer- Subduction -Volcanic eruptions produce a number of different hazards, including lava flows, pyroclastic flows and gas eruptions as well as secondary hazards such as lahars and jokulhaups. The main reason volcanic eruptions vary in magnitude is as a result of the type of volcano that is erupting which will produce various hazards to differing degrees. Magnitude is mainly measured by the VEI that measures things such as the v...

GEOG 1114 Physical Geography - Oklahoma State University. Locating the epicenter of an earthquake using trilateration Now, you will learn how data from seismographs in different locations are used to pinpoint the epicenter of an earthquake via trilateration. The material you need to refer to for this activity is in the file "Epicenter exercise package" on Canvas. The file has the seismograms for three locations (Marlow, OK, Carrier, OK, and Bolivar, MO), a scale with the P-S waves curve, and a...

Volcanoes: Ring of Fire - answer-Exists because of spreading of sinking plates at plate boundaries interact with other Earth materials to produce rocks. Volcanic Vents - answer-An opening through which lava and other volcanic materials are extruded onto the surface. Volcanoes: Decompression Melting: - answer-Overlying pressure exerted on hot rock within the asthenosphere is decreased. Magma will begin to form even though the temperature is constant. Volcanoes: Decompression Melting: Hot...

WJEC AS Geography Tectonics questions and answers Ridge push Rising plumes of hot magma cause the rocks in the lithosphere to bend upwards, forming a mid ocean ridge. Gravity causes the crust to slide downwards. Slab pull At a convergent boundary, the denser heavier plate is subducted, causing sea-floor spreading Convection Circular current that transfers heat energy from magma heated by the core to the crust. The magma cools and then sinks back down. Hotspot A part of ...
