What do you expect to find parallel to a rench? a.Hot sopt b.Ocean ridge c.Rift valley d.Volcanic arc Answer: d.Volcanic arc You will expect to find volcanic arc parallel to the trench. Explanation: The reason for this is because the denser oceanic crust undergoes what we call subduction process or the bending of the crust towards the mantle. This bending causes depression of seafloor creating trench. And the leading edge of the subducted plate the subducted crust melt forming magma. Addition of volatile material such as water will cause the magma to become less dense, hence allowing it to rise and reach the crust once again and causing volcanic activities on the continental leading plate. Which means, if there is subduction process, trench are formed parallel to the formation of volcanoes. Here are the three types of Volcano from biggest to smallest Shield Volcano Composite Volcano Cinder Cone Volcano Shield Volcano may not be the tallest Volcano but it occupies the bigges
