The correct answer is B Subduction. Subduction is the process by which an oceanic plate gets dragged under another plate and is eventually destroyed in the mantle. Subduction occurs at convergent margins where two oceanic plates collide or an oceanic and Continental plate collide. Oceanic crust is made of mainly of silica and magnesium which is heavier or denser than continental crust which is composed mainly of silica and aluminium.
The subducting plate melts producing excess magma giving rise to volcanoes along these margins.
The earliest of civilizations were based around river valleys. This allowed them to irrigate fresh water to their crops allowing for better farming and therefore, bigger and better civilizations.

<span>The word that should complete the sentence "Compressional stress on rock can cause strong and deep earthquakes, usually at _____" is reverse faults. Reverse faults are precisely the inverse of ordinary shortcomings. On the off chance that the hanging divider rises with respect to the footwall, you have a turn around blame. Reverse faults happen in regions experiencing pressure</span>
