Submarine Volcanoes Physics Essay
6 pages (1755 words) , Download 0 , Essay
Free
It has been estimated that the ocean floors around the world may be home to over a million submarine volcanoes based on the fact that the bottom of the Pacific Ocean alone bears 4000 volcanoes per million square miles. (Oregon Space Grant Consortium) However, since these volcanoes are hidden underneath the ocean, they do not directly affect human life and thus have been a relatively new study in the field of geology.

This has fueled, so to speak, a frantic search for new energy sources such as renewable energy sources like solar, wind, and tidal power. Fossil fuels like crude oil and natural gas are produced in wells which have seen declining extraction yields; the theory of “peak oil” was first put forward and popularized by Marion King Hubbert, who was a geo-scientist working at Shell, which is now primarily proven to be accurate as conceptualized and illustrated by the “Hubbert Curve.”

Velocity is a vector quantity that has both magnitude and direction. For the rate to be changed, both volume and order have to be changed. A body moves along a circular path with a uniform speed; thus, its direction changes instantly. According to Newton’s law, a force must exist to change velocity; this force is the centripetal force.
