> Moving to another question will save this response. Question2 How do we know the angle of a subducting plate? They always subduct at a 35 degree angle we record the locations and depths of the volcanoes and plot them, it is called the Wadati-bedati zone O we record the locations and depths of earthquakes and plot them, it is called the wadati-benioff zone O geologists draw a cross section and then someone measures the angle in the drawing A Moving to another question will save this response. d Kwasi Asante Ptrf...x Kwasi Asante.PHE isx PTREASL Homev. doc Cancelec 0

Explanation / Answer

2. The third option is correct: Dip angle of subduction plate can be determined by Geomapapp in which all the location and depth of earthquakes are plotted and all these points fall on the Benioff zone and the respective depth of the earthquake help us to draw a profile across the subduction zone.
4. Option 2 is correct: Accretionary prism or accretionary wedge formed from sediments accreted into the non-subducting plate at the convergent plate boundary. They mainly consist of marine sediments scraped off from the downgoing slab of the oceanic crust but sometimes they contain erosional products of volcanic island arc develop over the overriding plate.
6. Option 3 is correct: As accretionary prism agents of metamorphism are not dominant hence the sediments undergo. low-grade metamorphism with greenschist facies metamorphism.
8. Option 4 is correct: In any continental continental collision type of setup, all the type of rock can be associated with this mountain, eg Alps or Himalaya.
10. Option 1 is correct: South East Asia peninsula is the best example of lateral escape.
