In the Flattest part of the ocean the ___________ ______________ large ___________ can be found, rising from the ocean floor?

Abyssal plain, Guyots

Why does the formation of Magma result in it rising and pouring out a volcano?

The Magma is hotter and less dense and builds up pressure until and Eruption.
