How can the world end by floods?

Question

I mean maybe the human race along with everything else that can't breath underwater will die but the world will still be there and so will all the other animal creatures that survive under water will live on and so will the sea and the planet. I mean the only way the world can end is if it gets sucked into a black hole. I mean if an astorid hit it I'm sure plenty of creatures would survive too. I mean just look at the dinsors age. They died but some how we came out of it

Answer 1

Global warming will not kill off the oceans. Its happened before, its happening now. In the future it will happen over and over.
Can the earth end by floods? No. Humanity is too spread out for floods to kill everyone. Floods are strictly local events. Even if all the polar and greenland ice melts water level will only go up about 170 feet. That will drown most of the earth's cities, which are frequently found on sea coasts, but that sort of melting takes some time, and people will move to higher ground. After futilly trying to build seawalls of course.
An asteroid impacting the oceans can cause mile high (or larger) tsumamis, but those would be the least of our problems: large oceanic impacts would likely trigger mini-iceages. Now that could do the human population a serious hurt, but humans are very adaptable beasts and an iceage isn't likely to kill everybody.
I can think of three scenarios that would kill everything.
1. a wandering black hole swallowing us.
2. impact by a major asteroid or planetoid. The kind of impact that makes the oceans boil. Or cracks us open like an egg.
3. A passing star, brown dwarf, or black hole disrupting our orbit around the sun, throwing us out into the interstellar void, becoming a rogue planet. Life around the seafloor vents and deep undergound bacteria could survive, since energy for those creatures comes from the interior of the earth, but nothing else.

Answer 2

I'm new so I don't know where your question came from. The Bible talks about the world being ended by the flood of Noah's day. Maybe that's your point. This book will quite often use the word 'world' to describe the current collection of governments and lifestyles that are prevalent in the world. For e.g. Jesus was quoted as saying: "If YOU were part of the world, the world would be fond of what is its own. Now because YOU are no part of the world, but I have chosen YOU out of the world, on this account the world hates YOU” The actual earth wasn't what was referred to here because it can't hate anyone.
But if that's not what you are talking about; your right in a way, the actual earth in whatever form can't be destroyed because then you would have to destroy the energy that holds the matter on earth together. No one can do that. Even if every atom on earth came apart, the energy will still be somewhere.

Answer 3

Global Warming. It will destroy the water creatures because the conditions will change and it will start at the bottom of the food chain and go up. The tiny microscopic things will die so there will be no food for the next link in the chain so they will die and so on and so on. Eventually everything will die.
