how does  the earth creat?
94204
God created Earth and it underwent some processes.\nGenerally people use the theory of Big Bang.\n\nBased on my observations, this type of question is most likely to get little response.\nWhy?\nBecause people do not know about how Earth was really created. So do I.

When the earth formed, it was basically all just really hot rock.  So hot, in fact, that it melted.  When the rock melted, the heavier elements (iron and nickel) sunk towards the core of the earth.  This sinking of heavy elements transferred a lot of gravitational potential energy into heat energy.  The same can be seen today.  If you drop something heavy into a bucket of water, after you drop it enough, the water itself warms up.  This heat energy from the formation of the planet was the primary source of the heat of our planet.  However, another major source of heat today is the breakdown of radioactive elements inside the earth.  Both of these contribute to the heat the Earth generates.

It's widely believed in the scientific community that the earth has a liquid mantle (that's where magma/lava comes from) and a solid super-hot iron core.  Good luck digging through that.

Two main sources.  The first is that when the earth formed, it was very hot. The earth formed from a cloud of gas and dust, and then gained size from larger asteroids crashing into it for millions of years.  This left the early earth as a ball of lava. Because the earth is so large, it cools very slowly.\n\nSince the earth cooled from the outsize in, it eventually formed a crust, which insulates the inside even more, and slows down the cooling process. A good portion of the heat inside the earth is left over from its creation, about 4.5 billion years ago.\n\nThe other source of heat is the decay of radioactive elements inside the earth.  In the liquid early earth, the heaviest elements would have sunk to the middle. The earth's core is believed to be made mostly of iron, but there are traces of uranium and radioactive isotopes of  thorium, and potassium.

For weather you need hot and cold, wind and rain, snow and ice, and sunshine. The earth has plenty of those, and our weather is a world-wide heat-engine driven by the sun, the rotation of the earth, and the tilt of the earth's rotation axis with respect to its orbital plane as it orbits the sun. Thus we get night and day (hot and cold), seasons (rain, snow and ice), and cloudy or sunny days (and cloudy nights too, but it's hard to see clouds at night; and the Moon provides us with somewhat "sunny" nights a few nights every month).\n\nThe moon has plenty of hot and cold and sunshine, so some "weathering" of its surface does occur over billions of years of time, due to heat expansion and cold contraction of "stuff" on its surface. But without wind (no atmosphere) and rain, snow, and ice (no water) there is nothing to cause real weather like we have here on earth.

What people are treating the earth how?  The earth doesn't need anything done about it.

it is a little of both. yes the earth has heated but weather goes in circular movement. so there are periods of time when the earth heats up and then cools down. yes we are polluting the air and are loosing ozone, but the biggest factor is from methane gas produced by farm animals. we (Christians) are suppose to be good Stewart's of Gods gifts to us. so we need to learn to recycle, conserve and use the planet wisely. one of the things that would help the most is just planting trees. have an cooling effect on earth.

Because gravity pulls equally in all directions.\nAs soon as the materials that the earth is made of began to gather together under self-gravity, the center pulled equally in all directions.  As heat from friction and radioactivity made much of the early earth molten, gravity pulled it into the most efficient shape -- a sphere.  Because of the earth's rotation and centrifugal force, it's not quite a perfect sphere -- it bulges a bit at the equator and is slightly flattened at the poles -- but it's simply gravity doing what it does naturally.  It's why all large bodies are in the shape of a sphere.

The Earth is not a perfect sphere so you are at different distances from the centre at different places.\nThe density of the Earth is not constant so above dense rocks you appear slightly heavier.\nThe Earth spins so at the equator you are lifted slightly by the Eotovos effect.

Mountains are produced by forces in the earth that cause parts of the earth's crust to rise while others sink. Uplift of the crust, combined with chemical and physical erosion by air, water, and ice over millions of years, produces the spectacular scenery found in mountains. \n\nAt the very high temperatures and pressures found miles below the earth's surface, rocks can actually flow when density differences are produced by differential heating and cooling of parts of the mantle and lithosphere (Figure 1). The flowing of rocks in the mantle and lithosphere subjects parts of the crust to tension (pulling apart), while other parts are subjected to compression (squeezing together). Rocks are relatively weak and brittle under tension and, consequently, crust under tension tends to break up into giant blocks. Rocks are stronger under compression but when the compressive forces get very large, rocks deform by flowing, folding, and breaking.

All the mass on the earth is being pulled in by gravity, you and me included. the more mass you have the more an object pulls towards itself and others (basically heavy things have a sort of pull, so when you are by a huge mountain you are actually being pulled towards it) \n\nThe easiest way of all the mass to be pulled together is in a sphere, there are no corners and its cannot be compressed without other areas moving further away from the centre, so theoreticlaly the earth SHOULD be a sphere\n\nBUT it isn't; due to its rotation it is fatter than it is tall, because of mass being moved out by centrifugal force. \n\nhope this helps

For thousands, even millions of years, little pieces of our earth have been eroded--broken down and worn away\nby wind and water. These little bits of our earth are washed downstream where they settle to the bottom of the rivers, lakes, and oceans. Layer after layer of eroded earth is deposited on top of each. These layers are pressed down more and more through time, until the bottom layers slowly turn into rock.

It is because of the Earth's rotation.

first: by world, do you mean earth? \nIf so, think about all things spinning, are they not always more or less round or oval shaped? Actually so is the earth. \nOn the other way,I think that by spinning, a lot of things get that shape. Especially as like the stars and planets, they tend not to be in a fully finish state. Ok, that is my answer but I am no astronom only a nurse... MC

The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle. \nThe plates are made of rock and drift all over the globe; they move both horizontally (sideways) and vertically (up and down). Over long periods of time, the plates also change in size as their margins are added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick. \nThe map of the Earth is always changing; not only are the underlying plates moving, but the plates change in size. Also, the sea level changes over time (as the temperature on Earth varies and the poles melt or freeze to varied extents), covering or exposing different amounts of crust. \nThe current continental and oceanic plates include: the Eurasian plate, Australian-Indian plate, Philippine plate, Pacific plate, Juan de Fuca plate, Nazca plate, Cocos plate, North American plate, Caribbean plate, South American plate, African plate, Arabian plate, the Antarctic plate, and the Scotia plate.
