The first step of seafloor spreading is when a crack forms in the oceanic crust.
Explanation:
Seafloor spreading occurs in ocean waters. The force behind its formation is the convection currents in the mantle beneath it. When there are more intense convection currents in the mantle, it manages to have a big influence on the crust above it and break up tectonic plates.
The first step in the seafloor spreading comes in the form of cracking up of the oceanic crust. The convection currents manage to push huge amounts of magma under very high pressure and the crust breaks up. After this happens, magma starts to rise toward the ocean floor, as it gets out in the water it solidifies, and since the process continues for millions of years, the new magma that rises is gradually pushing the rock from the older one away.

Well I can't write an essay but I can give you some points:

-It looks really ugly(Just imagine a beautiful bay then you stick some wind turbines in the sea and it instantly looks ugly)
-Too expensive to build(solar panels are not cheap)
There's also another reason I didn't write your essay, it's because I suck at writing essays. I always end up putting a bunch of fancy and bombastic words that the teacher doesn't understand so she marks it wrong. I'm really sorry!
