If we did not have an ocean, how would it affect the biosphere?

Well hypothetically, if something were to happen...say aliens came down & sucked up the oceans... (LOL)\n\n1.)Weather...the weather is greatly affected by the oceans. Most of the moisture that precipatates as rain evaporated from the oceans. So you are looking at LITTLE to NO RAIN! That should tell you what would happen to life. We would be in major trouble! Also the ocean currents help control climates in places in the higher latitudes such as England & the rest of northern Europe. Warm water currents help make these latitudes warm enough to be habitable. No ocean means no current.\n\n2.) No more flounder, crabs, oysters, scallops, or any other yummy seafood! The only benefit I see from this is that jellyfish would become extinct. But since we would too I guess it wouldn't really matter anyways. LOL.

lithosphere ,hydrosphere,atmosphere and biosphere are realms of earth.Deforestration should be stoped ,stop polluting ,there should not be extreme rise in population as more population more pollution and more deforestration.Deforestration and pollution are the main reasons that would be a danger to our echo system which will surely destroy echo system and our planet earth.

The weather changes will have already happened if they're enough to make the icebergs melt.  \n\nRaising the temperature of the earth 8 degrees, sea levels will rise, flooding coastal areas. Heat waves will be more frequent and more intense. Droughts and wildfires will occur more often. Disease-carrying mosquitoes will expand their range. And species will be pushed to extinction.\n\nMore and more intense rainstorms and hurricanes.  Sea level rise will result in loss of coastal wetlands and barrier islands, and a greater risk of flooding in coastal communities.

OMG...this is a very sad question. The reason why gloval warming NEEDS to affect the earth is because without it, we would all DIE. Think about it, what would we do if there was no heat at ANYTIME. We would all die because we would all freeze to death. Besides in order to keep anything alive we need Gloval Warming. The food we eat need it, the water need it, the plants, animals everything and everyone needs it.

In the near future, scientists preidct of another Ice Age, followed by another supercontinent wear every continent comes together. Global warming would be temporary. Then, plants would die off, followed by the animals. This is because of teh growing sun and the heat created by it. Daily average temperatues would reach 100-35 degrees farenheit. Mitochondria stops working at 125-130 degrees farenheit. Thus, eukaryotic cells would die off and the earth would be left with bacteria-prokaryotic cells. Soon the heat of the sun would evaporate all of the oceans and only the hardiest bacteria would live, close to the Pre-Cambrian days. The surface of the earth would be so hot that it would melt, and earth would be swallowed by the expanding red giant sun. Before any of this happen, every 100 million years, a meteor larger than the one of the K/T impact that wiped out the dinos could hit us and kill everything except fot bacteria and another Ice Age would occur. Basically, the future represents the beginning of life on earth. bacteria-eukaryotic cells-higher animals-eukaryotic cells-and back to bacteria-no life.

The earth will completely dry up, because the atmoshpere that protects us and keeps air around the earth is being eroded.  Along with that will come increases in temperature that will cause methane stores in the bottom of the ocean to start dispursing, which will end up burning on the ocean, causing more evaporation, and without the atmosphere to keep the gases in, it the moisture in the air will drift out into space.\n\nI know, it sounds real "out there", but, seriously, I saw this on a NOVA special on PBS just last week!

The real answer is that we would almost certainly not have evolved without the moon; experts give these main reasons \n\nThe stability of the earth's rotational axis---it always remains nearly 23 degrees---is due partly to the Moon's presence; without it, the Earth's axis would wobble much more violently, so that seasons would be far more severe. [This wobble would occur over thousands to hundreds of thousands of years, but that might have been enough to affect evolution dramatically.] We could even from time to time orbit on our backs like the planet Uranus!\n\nThe length of the day might have been much shorter.\n\nThere would be greatly reduced ocean tides or tidal reaches so that the development of much of marine life, and certainly the development of Amphibian and the settlement of Dry Land, would have been greatly affected, perhaps prevented.\n\nAs for the present, our civilization might find it hard to adapt to a sudden withdrawal of the Moon, but could learn to cope with a slow drifting away---which is in fact occurring at a rate of about 3 cm/year. \n\n\nThat is the "short" answer, but if you want more information, this website explains in detail, but in easy terms how the moon and earth interact and so you can conclude further for yourself what the planet would be like without it.\n\nhttp://www.astronomytoday.com/astronomy/earthmoon.html

All carbon based life would immediately cease. Since "no water at all" means our bodies as well, including our cellular structure, we would all just be dessicated husks.

Effects of deforestation.\n\nthis can be a local problem with global consequences.\n\ncan be biology and chemsitry (maybe physics as well, heat flows etc.)

A.  All the rest have a major impact on the viability of the earth. They will effect the earth even if humans are left out of the equation.

If the Tooth Fairy waved her magic wand and ...\nAre you serious?\nDividing the Earth in two parts without damaging the surface would require ... magic.\n(Of course Arthur C. Clarke did once point out that any sufficiently advanced technology would appear as magic but we're talking an asteroid strike, not super-technology.)\nIf a body large enough to blast the Earth apart struck, there would be nothing presently on the surface that would survive in recognisable form.\nI suppose it's imaginable that two bodies mutually orbiting a common center of gravity, might accrete from the resulting debris. The oceans would have been vaporised. Some water would recondense and wind up on our hypothetical twin Mini-Earths but I imagine on the whole they'd be pretty dry. Bacteria living in deep crustal rocks blown clear of the remains of the planet would probably  survive and as this debris was gravitationally 'swept up' over time by the newly formed pair of mini-Earths life would be re-seeded and we'd be back at 'Square One'.

A wide variety of wierd things would happen.  For one temperatures would increase more and decrease to lower values on the sunlit and shaded sides of the world.  Ocean currents and weather patterns would change dramatically.  Winds would blow directly toward the equator in both the southern and northern hemispheres.  Large circular currents called gyres which exist in all ocean basins would dissapear.  The tides would also be much different because the earth's rotation strongly influences tidal characteristics.

For starters there would be no tides. Moon is responsible of tides, since its magnetic field affects the sea level. Also, visibility at night would be significally reduced.

Well, if it were totally enclosed, it wouldn't be an ocean. Partially enclosed would be a sea, or a bay, or a fjord, or an inlet, or a cove, or a harbour, all depending on how large the enclosure is.

i can tell u what would happen if we had no moon... this is the answer... \n\n\nIf the Moon did escape from Earth, the main effect would be the lack of tides on Earth. Tides are caused by the differential gravitational force on the equatorial regions: i.e. the region closer to the Moon experiences more gravitational force than the region on Earth away from the Moon. This results in the formation of high and low tides on different regions of the Earth. \n\nOther than tidal forces, there is no other geological or climatic influence of the Moon on Earth. There are issues like no more Moon to light up the night sky, no more solar eclipses, etc. but there will be no change in the geology or climate on Earth.

Salinity will decrease a bit, but it won't be very significant.  \n\nLower salinity fish might move out of their environments and colonize other parts of the oceans.

We would stay in essentially the same orbit around the sun and gravity on earth's surface would remain normal.\nTides would be solar-only, about 1/2 to 1/3 what we have now. (Lunar-only tide amplitude is about twice solar-only tide.) This change would cause a major adjustment to shore life and possibly to birds that travel extensively over ocean waters but would not be disastrous to land-dwellers. Loss of night-time illumination would affect nocturnal animals somewhat, but they do without moonlight for several days per month as it is. Bottom line, not a major threat.
