Question

Research has shown that melting begins to occur at the subducted plate arrives at a depth of 110 km below Earth's surface. The lower density magma rises to the surface and erupts as volcanoes. Using the arc-trench gap distance and the following equation, determine the decent angle 0 at which the pate is subducting. (3pts) e.

Which of the following is incorrect: (Circle one) (1pt) 1. The subducting plate is to the east and the overriding plate is to the west 2. The subducting plate is to the west and the overriding plate is to the east 3. You are unable to determine this information from data provided g. True/False. The Volcanic Arc is always located on the subducting plate. (1pt)

Explanation / Answer

1.Assumming arc trench gap = 100 km

so tan-1(110/100)=47.72 degree

2.incorrect one is- subducting plate to the west and overriding plate to the east.

3.No volcanic arc always located on overriding plate. so the above statement is false.
