It's called methyl clathrate, a clathrate compound which consists of methane trapped within a crystal structure of water similar to ice.
Oil, coal and natural gas are the three main fossil fuels found in Mexico.
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.

It is the mid-ocean ridge.
That is called subduction.

Yes, Dr. Robert Ballard found the Titanic split in two on the ocean floor. The bow and stern sections are lying 2,000 feet apart on the ocean floor. It is suspected that trapped air in the hull completed the breakup that began when it sank. The front half of the wreck is in substantially better condition.
The bottom of the ocean is part of a tectonic plate or continental shelf, or can be on the breach line between two shelves.
Magma erupts along mid ocean ridges forming new ocean floor. Mid ocean ridges are found at divergent boundaries where two ocean plates are pushing apart.
I'm assuming you're talking about the ocean floor itself (the earth's crust). The youngestmaterialat the bottom of the ocean is at the riffs between two plates. The mid-Atlantic riff is a good example.
