What are facts about the Pacific ocean?

Answer 1

it is the oldest ocean ever

it has different types of animal

it is also the deepest

______________________________________________________________

The Pacific Ocean is the largest and deepest ocean TODAY, but it is not the oldest ocean EVER.

It was formed during the Triassic period of the Mesozoic era, after the broke-up of the supercontinent Pangaea.

The Pacific Ocean is the remaining part of the much larger Panthalassa Ocean, a superocean that covered all Earth surface, except Pangaea.

And even Panthalassa is far from beeing the first superocean.

As far as paleogeologic and paleomagnetic studies can presume, there were since the formation of our planet several supercontinents, each surrounded by superoceans:

- The first supercontinent believed to have existed is commonly named Vaalbarain the scientific community (the existance of this first supercontinent is controversial, due to the scarcity of paleogeologic data available).

It may have formed about 3,600,000,000 years ago, during the Archean eon and nobody knows for sure when it began to break up, perhaps 2,800 My ago.

This first superocean still have no formal designation, and was not yet made of salt water, as today's oceans.

- The second supercontinent was Ur, formed 100 My after the broke up of Vaalbara.

Significantly, it was much smaller than the total combined area of all present continents, possibly smaller than Australia, and it was surrounded by one of the largest superoceans ever in geologic Earth's History.

There is also no scientific name for this second superocean surrounding Ur.

- Columbia was the next supercontinent, and geologic evidences and paleomagnetic orientation suggests a duration from 2,100 My to 1,600 My, during the Proterozoic eon, just after the end of the longest - and, most probaly, the more severe - Snowball Earthglaciation ever (the Huronian Glaciation).

The Geological Society denominate, informally, the first three superoceans as «Oceans of Ignorance».

- Supercontinent Rodinia formed 1,100 My and broke up 750 My BP. Unlike the later supercontinent Pangaea, Rodinia was entirely a rugged and barren landscape.

It was surrounded by the first superocean scientific community gave an official name: the Mirovia Ocean.

During the Cryogenian period of the Neoproterozoic era, the Earth suffered the second Snowball glaciations episode, and Mirovia is thought to have been completely frozen to a depth of 2,000 metres.

- The last superocean was the Panthalassa, above mentioned.

But a new supercontinent will be formed, no doubt, in perhaps 250 My from now, following the Wilson Cycle, and it already has three possible names:

- Amasia, Novopangaea and Pangaea Ultima...
