I had this, i think it was conduction or plate tectonics.
Answer: Volcanoes form at B when the oceanic plate is subducted, and the plate melts and forms magma. This magma rises towards the surface and erupts as lava which forms the volcanoes. It can be found in Pacific Northwest in northern CA, Oregon and Washington. The boundary in B shows converging plate boundary. An oceanic plate collides with a continental plate. The result is the oceanic plate sinks below a deep ocean trench into the mantle. The boundary shown in A is a diverging plate boundary. 2 oceanic plates diverge to form a mid-ocean ridge.
Exceptions to A and B are when volcanoes form at hot spots in the middle of continental or oceanic plates. Magma melts through the crust and moves to the surface in a hot spot. Also a collision between two oceanic plates can form volcanoes. One of the oceanic plate is subducted which melts the plate and the formation of magma which erupts to form a chain of volcanic islands called an island arc.
Explanation: I took the test and aced it so i hope this helped
Well ersion is one them because when any wheter hits us it usaully cause the roads grounds and ect to break other part of climate is polution do to the fact power plants, oil field, and gasoline all those thibgs go up to the clouds and and when it rains all the polution is sent back on to raods house and ground.
Sunlit zone is depth of water exposed to sunlight, trenches is a long narrow ditch.
Focus on the general impression of the scene and simulate reflected light.
