elmat, you may be good at telecoms but your geology is a bit rusty, to put it politely!

Yes, the coasts of West Africa and South America do match, as do the rock composition of Nova Scotia and the UK.
They were joined at one time.
The mid-Atlantic ridge stretches from East of Greenland to the extreme South Atlantic.
It is a long line where new Earth's crust is created, as Magma wells up from kilometres down and cools.
It is a vast spreading feature. Think of it as the line where two conveyor belts rise up and slowly push outwards, away from each other, with North and South America floating away from Europe and Africa.
There is no oil near the mid-Atlantic Ridge, but there is a s**t-load of hydrothermal energy!

"Under the ocean floor there are canyons formed by the water dropping from the continent into the rift opened between Africa and South America."
Question.
Are you implying that there are vast waterfalls on the coast, cascading down onto the fiery mid-Atlantic ridge and carving out canyons?
I think that is what you are saying.
You are obviously someone who is keen to learn as you read a lot. Buy an introductory geology book for cheap from a used book store. Make sure it is post-1980. It will open up your world. Seriously!

"The deltas are below the salt."
Say what?
I think you have that backwards ... or is that upside-down?
The world's Deltas are at surface. They are below air.

Salt bodies (no relation to me!) that form hydrocarbon traps can be found beneath these deltas and other sediments.
The salt layers were formed by evaporation in shallow waters over a long period. They were then buried beneath new sediments.
The formation of salt domes is a complex process and a lot can be learned by Googling.

Cheers,
S&P
