If the world turned into a giant tangerine, what of its effects and would its over-all structure survive?

If the world suddenly turned into a tangerine, it would burn up and start to "fall/move" twords the sun.  It would probably split apart, and no life would survive.\n\nHowever, the chances of that happening are very, very slim, and If I were you, I wouldn't worry about it.  I mean really, really don't worry about it, there is a better chance of the world turning into an overcooked Mud Pie, so that is what you should be worried about instead.

NONE.  All things were created!  Things adapt to changing environments, but they never turn into something entirely new.

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.)

venus would crush it from the dense atmousphere,, mercury would burn it up, mars could possibly let it survive with a little help,jupiter,saturn,uranus,neptune,pluto would freeze all things

Sun explode. Sun go out. Ceres-sized bolide hit Earth.\n\nNo disease, weather or ecological phenomenon could completely wipe us out. Even we couldn't wipe ourselves out; we are just to numerous and smart.

It would destroy the Earth. And I'm not being facetious.\n\nIt would destroy the Earth in many ways. First, it could actually break the crust of the planet. This alone could break us into multiple pieces.\n\nLet's say for sake of argument that you set it off in a place that isn't seizmically active, and you just blow away a big chunk. More nastiness ensues.\n\nSecond, the dust cloud would encircle us, and the temperature would drop. Instant ice age, everywhere.\n\nThird, the Earth is remarkably fragile. We're exactly the right distance to be warmed by the sun, but far enough not to be cooked by radiation. The hole created in the atmosphere would remove that protection.\n\nFinally, our orbit will be thrown off. Maybe not enough to be thrown into deep space, but enough to make us tumble in scary ways.\n\nBasically, the end of the world as we know it.

nothing at all!\nYou'll have to leave evrerything,bank account,cars,buildings....\nIsn't it time to think of an eternal world?

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'.

The Earth would lose sea tides and other water tides.  This would mean the sea receding in some parts of the world and flooding in other parts.  I also think that the Earth will "wobble" on its axis and its path of revolution around the sun would change.  That would mean change in the duration of the day and the year, I guess that would mean toal destruction.

Probably mostly positive. The soil would be richer so plants would grow better making more food for all creatures locally. That would result in greater biodiversity.

Don't forget that large bodies like the earth itself, and the sun, are themselves held together with gravity.\n\nProbably the first thing that we would notice is that the earth would immediately lose its atmosphere as it went flying off the planet into space, as would the oceans.  Everything on the surface of the planet would go flying off due to the centrifugal force of its spinning ... buildings would just rip off their foundations like cheese shaking off a cheese-puff.  Without an atmosphere, it's doubtful you and I would live more than 15 or 30 seconds.\n\nThe earth  would immediately break apart in a big cloud of hot liquid iron (the core of the earth) and all the stuff on the surface.\n\nThe moon would also disolve into a huge cloud of hot rocks and sand.\n\nThe sun would explode rather violently, as the pressure from the burning of the inner core would suddenly have no force counteracting it.  The same would be happening to every star and planet in the universe.  And galaxies themselves would fly apart (as they too are held together with gravity).\n\nAnd yes, what is left of the earth would fly away from what is left of the sun ... although it would be quickly overtaken by the exploding sun.\n\nBut, of course, it ain't gonna happen.  I'll bet everything I own on it.  :-)  \n\nThink of this as a great way to get back in with your girlfriend ... "Hey baby, if gravity were suddenly to disappear, we need to be holdin' each other really tight!"  (You take it from there).

It's not the money!\nIt's the fact that the earth will be terribly out of balance and mother nature will take a drastic nose dive if there are not more forests.  All life will probably die.\nOur atmosphere is created by all the plants and trees giving off all their oxygen.  Earth would not be the beautiful life supporting place that it is without trees.

Can the Earth sustain itself?\nOr us?\nThe earth will be around longer than we will.

my interpretation is that the existance of humanity will be long enuf to see the montains move. think of it this way, if you were omnipotent and watched thre earth through time you would see the lands shift and mountains melt away with erosion.

A broad answer is that all life will either adapt to these changes to survive or face death and/or extinction.\n\nThe earth has always changed and will continue to change. Many of these changes can be caused (and stopped) by man..for example reducing pollution that could be contributing to global warming. Most changes, however, are due to forces outside our control or contribution. \n\nClimate changes aren't necessarily under our control or prevention. There is a complication. The Earth's orbit is very close to being a perfect circle, but not quite. It is somewhat elliptical, which means that the distance between the Earth and the Sun varies over the course of the year. This effect is too weak to cause the seasons, but it might have some influence over their severity.\n\nThere is another important cycle that has the potential to affect the Earth's climate; it is a 41,000-year variation in obliquity, the tilt of the Earth's axis. The obliquity varies by only a few degrees back and forth, and the current value of 23.4° is near the middle of the range. However, in respect to climates on the earth, the obliquity variation has the potential to have a fairly direct effect on seasonal extremes. After all, it is the obliquity that causes our seasons in the first place - if the Earth's axis were perpendicular to its orbital plane, there would be no seasons at all.\n\nAnother factor is our moon. Our moon has a huge influence on our life here on earth on many levels, yet it is slowly moving away from us. It also is a factor of keeping the tilt of the earth's axis from taking bigger variations than it does now. As it moves farther away, the "wobble" will likely become much larger and the changes in climate on a much larger and more frequent time frame.\n\nWhen one takes into account the possibility of asteroid impacts, the immediate and long-term effects caused by plate tectonics, and many MANY more changes in our earth that are beyond human control, we see that human-influenced global warming is only a small piece of a very large changing earth puzzle. (I mention this not to say that global warming isn't a very important topic to teach, but to stress that the other causes of climate changes should be taught as well. Most school-aged children tend to think if we simply address the burning of fossil fuels there will be no climate changes on earth.)\n\nThe changes I have mentioned here are earth/space science topics. Many other changes occur on earth that are usually covered in life science classes. Hope this at least gives you some ideas to explore and research further.

Everyone would have everything they need or have ever dreamed of. \n\nOr the world would come to an end by the mere force of the bag being turned inside out, upsetting the parellel universe where all of the items of the bag come from.

Interesting question.  We would no longer have the moon's tidal forces, so no more high and low tides.  This would destroy the vast ecosystems along shorelines that depend on tides for their existence, and could well cause very negative effects on the Earth's entire balance of life, since these areas produce the most nutrients.
