Volcanic island arcs are created by volcanic activity associated with the subduction of the oceanic plate.n some situations, both plates can include continental material such as where the Indo-Australia plate is subducting beneath the Eurasian plate.

The Hyksos brought with them knowledge of bronze weapons, chariots and composite bows. But it is not clear that they were required to use this military know-how to take control of upper Egypt.
