As with any theory, it is made of ideas, and thoughts.
I know of many theories involving the ocean, but none specifically called oceanic theory. I have done some research, and found nothing relating to an "oceanic theory."
Scientifically speaking, a theory is one of the steps in the scientific process.
1 Observation
2 Hypothesis
3 Experimentation
4 Results (if results don't agree with hypothesis, return to 2)
5 Theory
The process is repeated many times to rule out chance, and if you get the same results every time, it can scientifically be called a theory. If you continue on to scientific proof that your theory is correct and cannot be explained in by any other means, it becomes scientific law. However, very little is actually scientific law in modern science. Even gravity is only scientifically a theory.
Theory that oceanic crust forms along submarine mountain zones, known collectively as the oceanic ridge system, and spreads out laterally away from them.
oceanic crust
i genous rock
Yes
Continental crust is made of granite. Oceanic crust is made of basalt.
Continental is made mostly of granite. Oceanic is made mostly of basalt and gabbro.
Oceanic and Continental crust. Oceanic crust is made of basalt. Continental crust is made of granite
The main mineral type in Oceanic plates are made of basalt
A tectonic plate consists of a piece or fragment of the earth's lithosphere, which is in turn composed of the earth's crust and that portion of the earth's upper mantle which behaves as a brittle solid through which fractures can propagate.
how many tectonic plates are made of oceanic crust
It is made of Basalt.
