Question

What is the tectonic setting for each lettered location on the diagram? (continental hot spot, divergent boundary, oceanic hot spot, or sub duct ion zone) each tectonic setting should be used only once. What is the average composition of magma erupted from each location? (mafic, pelvic, or intermediate) What type of volcano(is) is/are found at each tectonic setting? (caldera, cinder cone, composite cone, volcanic dome, or shield volcano) each volcano name will be used twice, except "composite cones" which are only found in ONE of the locations. There should be one volcano name per blank. At each of the four locations on the diagram, sketch the one volcano that is most commonly found at that tectonic setting. Draw the volcano directly on the diagram and be sure to draw it to scale (i.e. think about its relative size, shape, and position). you will only be drawing the following three volcanoes: composite cone, shield volcano, caldera, and you will draw one of them more than once. VI point.

Explanation / Answer

1)

A - It is a divergent plate boundary in the oceanic crust

B - It is a oceanic hot spot,where the volcanic vent is intruded into the oceanic crust

C - It is a subduction zone where oceanic plate subduct under continental plate

D - It is a continental hot spot,where the plume come through the vents to earth surface.

2)

A - The magma formed at Divergent boundaries is Felsic because of  partial melting

B - The magma formed at oceanic hot spot is basaltic or mafic lava

C - The magma formed at convergent boundaries is mafic, Where the subducting oceanic plate reaches depths of between 100 and 150 km.

D - The magma formed at continental hot spot felsic magma. The felsic magmas form as the rising basaltic magma melts some of the continental crust.

3)

A - The volcano formed at divergent boundary is shield volcano

B - The volcano formed at oceanic hot spot is broad sloping shield volcanoes

C - The volcano formed at convergent boundaries is Composite and Cinder cones.

D - The volcano formed at continental hot spot is cinder cone ,shield voncanop
