What feature may form over an intraplate area over a rising plume of hot mantle material?
A volcano. See the excellent book "Krakatoa" by Simon Winchester.
What are continent-sized columns of superheated mantle material originating at the core-mantle boundary and rising upward due to a change in density?
mantle plumes
What are columns of hot rock rising through earth's mantle called?
Plumes.
Hot spots are areas of volcanic activity located over rising?
Mantle plumes
What is mantle plume?
A mantle plume is a rising mass of extra hot mantle rock. Mantle plumes are though to be the cause of volcanic activity away from plate boundaries.

What is the difference between a hot spot and a focus?
The focus is a feature of an earthquake; it is the point underground where the earthquake originates, directly beneath the epicenter. A hot spot is an area away from a plate boundary that produces volcanic activity, most likely due to a rising plume of extra hot material in the mantle.

What is definition of isotasy?
Isotasy is suppose to be spelt as Isostasy which means:The equilibrium that exists between parts of the earth's crust, which behaves as if it consists of blocks floating on the underlying mantle, rising if material (such as an ice cap) is removed and sinking if material is deposited. This answer is from Google definitions. I do not own any content.

Mantle plumes
what is the process of the sea floor?
Spreading of seafloor occurs at the mid-ocean rifts, where there is a continuous flow of material rising from the mantle. There is not a unanimously accepted theory as to the cause of the rifting that is taking place. Once the rifting and mantle material inflow has started, however, the conduit is in place. The thinness of the crust at the rift makes it easier for the material to rise, and as it rises it becomes molten and emplaces itself to form new oceanic crust when it solidifies. The rising material is part of a convection current in the Earth's mantle. At the opposite end of the current are subduction zones, where oceanic crust sinks back into the mantle and melts, causing surface features as composite volcanoes. With this cycle of creation and destruction, the total area of seafloor remains relatively stable, but continents change in relative position to each other. These changes do not occur rapidly. The average speed of crustal plate movement is less than the average rate of fingernail growth.

Are hot spots stationary?
Yes; hot spots are huge columns of hot mantle material rising from a great depth. New volcanoes form and old volcanoes become extinct as plates move over the hot spots.
