crust-core convection
The idea that plate motions are caused by electromagnetic forces has not been widely proposed as a mechanism of plate motions. The most accepted mechanism is the theory of plate tectonics, which suggests that plate motions result from the movement of convection currents in the Earth's mantle. Other proposed mechanisms include ridge push, slab pull, and mantle plumes.
There are several sources that are proposed to meet future energy needs in a renewable way. Solar, wind, and biomass energy have all been proposed and all have pros and cons.
The cathode "ray' must have been made up of negatively charged particles, now called electrons.
A photo plate is usually a glass, or metal plate, coated with light sensitive chemicals. Until used it was kept in the dark. It was placed in the camera and exposed to the light of the scene, then removed, and stored in the dark, until it could again be chemically treated to reveal and fix the image on the plate. The glass plates produced images that could later be used to produce a copy of the image printed on paper by shining a light through them. Metal plates produced the image on the plate itself. They could be the end result, or be used in specific printing techniques to make copies in a printing press. The metal and glass plates were replaced by plastic film, and now the film has been replaced with electronic sensors. Even the term photo plate has been replaced with the term photo mask.

It's a place where gravitational force has been accurately measured, usually marked with a bronze plate with the results. Here's a link: http://www.holoscenes.com/cgi-bin/moin.cgi/gravity_station
the Kobe earthquake wasn't caused by a volcanic explsion, yes it occured at a destructive plate margine where the phillipine plate subducted under the eurasian plate but no vulcanism occured, the friction caused by the subduction caused the earthquake which has been identified to have a strike slip mechanism
Feline is a good word for someone who moves with the grace and fluid motions of a cat.
A proposed explaination for an observation is called a hypothesis.
The origin of life remains a subject of scientific investigation with no definitive answer. Various hypotheses and theories have been proposed by scientists such as Alexander Oparin, J.B.S. Haldane, and Stanley Miller, but the exact mechanism of life's origin is still unknown.

Proposed legislation bills can be defeated by opponents after they have been introduced. The members of the House of Representatives or the Senate can vote down the proposed bills.
