the derivative of 1x would be 1 the derivative of x to the power of 1 would be 1. the derivative of x+1 would be 1 the derivative of x-1 would be 1 im not sure what you are asâ¦king, but however you put it, it's 1. 2 people found this useful.
Subduction-zone stratovolcanoes, such as Mount St. Helens, Mount Etna, and Mount Pinatubo, typically erupt with explosive force: the magma is too stiff to allow easy escape of volcanic gases. As a consequence, the tremendous internal pressures of the trapped volcanic gases remain in the pasty magma.
In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide. The collision between the Australian Plate and the Pacific Plate that formed the Southern Alps in New Zealand. 2  Subduction of the northern part of the Pacific Plate and the NW North American Plate that is forming the Aleutian Islands.
