What is the shape of the earth?
The earth is often thought of as spherical (like a ball), but it is closer to being an oblate spheroid. An oblate spheroid is a sphere that is slightly bulged along the 'equator'. We can create a reference oblate spheroid, a theoretical closest fit to earth, and the over-all tolerance between the actual geoid, the earth itself, and the reference oblate spheroid is extremely close-- even closer than the tolerance allowable in billiard balls. See the article for more details and specific measurements.

When plate tectonics run into each other they create force whichcauses the mountain to have a big lump. eg: if i layed clay in themiddle of two blocks and i squished it together its going to createforce which makes my clay lumpy like a mountain or a tsunami oranything else that's on that line. .
definatly because when volcanoes erupt the lava hardens and some times in big piles so yes they do
The shape of the earth's orbit is called a ellipse, or it goes in acircle.
water. ______________. Basically, gravity shapes the earth. During the time that it was acquiring more and more mass from the disk of materials in its path, it reached a point where simply by the weight of its own components it began to collapse into a shape that was more and more sphere-like. Thi…s in fact is one of the requirements for a body to be considered a planet. In terms of erosion, water wind heat microorganisms plant and animal life all play a part in shaping certain aspects of the surface. But the fundamental shape of the earth is under the control of gravity. ( Full Answer )
Water shapes the earth by erosion. Erosion is when water loosens upthe soil and causes it to become loose and separates from riverbanks and from the sides of mountains.
Short Answer: Earth is an oblate spheroid, slightly bulged at the equator. (0.3%) Centrifugal force and gravity together are responsible for theshape of the earth. Explanation: If the Earth were not rotating, it would only have gravity pullingall of its parts together and that tends to form a …perfect sphere.It is not perfect, but the earth takes the shape of an oblateellipsoid due to centrifugal forces perpendicular to the axis ofrotation. The centrifugal force gets larger as the distance fromthe axis of rotation increases, so it is zero at the poles andincreases to a maximum at the equator. History: In 1687 Isaac Newton published in the Principia a proof thata rotating body with gravitation would develop a surface in theshape of an oblate ellipsoid. (The term oblate spheroid means thesame thing.) Half a century later, this became controversial in Europe and in1736 the King of France sent the mathematician and physicist PierreLouis Maupertuis on an expedition to Lapland to do the necessarygrade measurements. Data: The Earth's equatorial radius (semi-major axis) is the distancefrom its center to the equator and equals 6,378.1370 kilometers(3,963.1906 mi). The Earth's polar radius (semi-minor axis) is the distance from itscenter to the North and South Poles, and equals 6,356.7523kilometers (3,949.9028 mi). The surface of the Earth is obviously not smooth and mountains andtrenches represent variations of several kilometers (or miles),about 0.2%. Other relatively minor variations in the shape of theearth are due to variations in the density of the crust andgeomorphological processes. ( Full Answer )
The true shape of the earth is oblate spheriod. This means that the Earth is slightly flattened at the poles and slightly bulging at the Equator.
It doesn't really change the shape of the earth in a whole, but i does kinda can the shape of one area. Deposition is the depositing of sediment to build up layers. So it will make a certain area have thicker ground.
That is due to gravity. Any large deviation from a spherical shape - such as a mountain that is more than a few kilometers high - would be squashed down by gravity.
The Sun and its planets are all basically spheres. The earth is an 'oblate sphere' - that it, it is flattened at the poles.
they alter the earth by moving around and just shaping it in different ways.. like when they move, the earth changes.....
The shape of the Earth is round. It is a circle, or sphere. Notflat, but more like a ball.
The technical name for the shape of the Earth is geoid . This is studied in the science of geodesy.
the shape of the earth is not flat. it has a spherical shape. its slightly flattened at the poles to give a nearly spherical shape hence; the earth's shape is better described as a geoid which means the earth's shape
It's not shaped like a banana. . that's right . wat idiot wuld ask dat? .
They cut through valleys and down mountains and cause the soil to move aside. Sometimes they can meander back and forth. Here are the 3 things that are involved in helping to make a river: . EROSION . DEPOSITION . WEATHERING
The name "Spaceship earth" came about because the earth moves through space and it is holding people just like a spaceship.
It is not an actual sphere.This is since that when the earth turns on its axis so quickly for twenty four hours ,the poles seem a bit flat and the sides east and west are bit rounder.It is an OBLATE SPHERE !
In a word..Gravity. First off dust particles accumulate which increases their mass and therefore increases the gravitational pull. This attracts larger bits and so on and so forth until either the object runs out of material to attract or is assimilated into another, yet larger object with a greater… gravitational field ( Full Answer )
Many of the processes that changed the Earth in the past are thesame processes that operate in the present.
Simple Answer: The Earth has a spherical shape because of gravity. Each tiny bit of the Earth is attracted to every other bit of the Earth. The force of gravity pulls everything together and the only shape that leaves no part with the possibility of getting any closer to any other part is the sha…pe of a sphere. One can also say that this is the lowest energy configuration. The Effect of Rotation: If gravity were the only force involved, then the Earth woud be a perfect sphere, but because the Earth is rotating, there is also a centrifugal force. That force is greatest near the equator, pushing outward, and decreasing the effectiveness of gravity. Thus, the Earth has a bulge of about 0.3% at the equator and technically the shape of the Earth is an oblate spheroid (also called an oblate ellipsoid). Details: The Earth's equatorial radius (semi-major axis) is the distance from its center to the equator and equals 6,378.1370 kilometers (3,963.1906 mi). The Earth's polar radius (semi-minor axis) is the distance from its center to the North and South Poles, and equals 6,356.7523 kilometers (3,949.9028 mi). The surface of the Earth is obviously not smooth and mountains and trenches represent variations of several kilometers (or miles), about 0.2%. Other relatively minor variations in the shape of the earth are due to variations in the density of the crust and geomorphological processes. ( Full Answer )
The gravitational magnetic field surrounding the earth is what shaped the Earth into a perfect sphere. Others argue that God shaped the Earth.
The Earth is not technically an ellipse since an ellipse is a planar figure. But one can ask if the Earth is an ellipsoid, which is a 3-dimensional figure. The Earth's shape is usually described as an oblate spheroid, which means its diameter is greater through the equator than from pole to pole.… Oblate spheroids are ellipsoids (in fact they can be swept out by rotating an ellipse around the pole, where the minor diameter of the ellipse is aligned with the axis of rotation). That the diameter of the earth is greater thought the equator than pole-to-pole is due to the centrifugal force created by the rotation of the earth. the earth is generally round to some people but accordin to scientist the earh is spheri cal in shape ( Full Answer )
The earth in Philippine folklore was shaped by a god or creator.The folklore also states that gravity forms the earth into itsshape.
the proof is 1. is the earth moving?-NO. 2.is the earth bouncing?-NO 3. is the earth moves around?-NO!
they do in the areas where they hit the hardest. Grounds have raised and grounds have been lowered by earthqueakes and other grounds have been separated.
Geologic forces that shape the Earth are weathering and erosion (from wind, ice, water, and gravity) and the results of plate tectonics (volcanism, earthquakes, mountain building, subduction, crust creation).
the shape of the earth is called an oblate spheroid. the answer is from wikipedia. it is also called an ellipsoid.
1. weathering . -physical and/or chemical 2. erosion . -different agents of weathering 3. mass movement . -land and mud slides 4. tectonic plate movement . -convergent and/or divergent 5. gravity
Simple answer - They are sphere's . Relatively simple answer - They are oblate spheroids . Complex answer. The Earth and Moon are oblate spheroids (The Earth to a greater effect), whereas the Sun is a gaseous body so it experiences an extended oblate spheroid property.
The more common answer would be that the earth is a sphere. However, this isn't quite true. To be completely precise, the earth would have to be described as an irregular oblate spheroid . An oblate spheroid, in planetary terms, is a sphere-like figure whose equator is stretched relative to its pol…ar axis. "Irregular" refers to the fact that the earth does not have a smooth surface but rather many mountains, valleys, oceans, etc. ( Full Answer )
They believed it was like a giant plane, and that if you went too far toward the horizon you would fall off the edge of the earth.
Polaris (the "North Star") has no connection with the shape of the earth, and no influence on it.
The earth is slightly pear shaped the north pole radius is 44mm longer than the south pole radius i hope that answered your question. I had an assignment today with the question what shape is the earth sounds like a stupid question that a teacher would ask a twelve year old because he is a social st…udies teacher. He said he wouldn't know if the earth was slightly pear shaped and my friends wouldn't believe me. I was proven correct by the Internet when one of my friends looked it up. This was just a little story about how i proved something nobody thought was true! ( Full Answer )
Ignoring stuff like mountains, almost perfect spheres. Because of spin, the polar diameter is slightly less than the equatorial diameter (oblateness).
The earth is not perfectly round, but very slightly flattened at the poles, and with a very slight bulge at the equator - the shape is called "oblate". It is caused by the earths rotation on it's axis. Jupiter, which rotates much faster than the earth has even more pronounced bulging at the equato…r and flattening at the poles. It is not really obvious to the eye, but can easily be measured with scientific instruments. ( Full Answer )
Spherical. They are approximately spheres. The earth is more of an oblate sphere, a squashed sphere - this is due to its spin.
If you count the atmosphere then yeah, maybe. you always have to consider the little bit of debree that might be there if there is any at all. But the Earth itself isn't a perfect sphere. Just think about the mountains and stuff, rough terrain, the different sea levels. Think about it.
Earth's shape is described as an "oblate spheroid", in other words, a very slightly flattened sphere.
The rotation of the Earth produces centrifugal force, which causes the equator to bulge. The Earth therefore has the shape of an oblate spheroid.
Floods move the earth(soil) and deposits it at another location. this process changes the shape of the land
Glacial movement causes erosion of the Earth's soil (by moving across the ground). It also will leave behind lakes/ponds if it melts.
It isn't "special in shape" - Earth is round, like a ball, justlike any other planet.
The main thing is gravity which makes the Earth more or less spherical. The Earth has a small "bulge" at the equator because of its rotation. I suppose this question might be about what things affect the shape of the Earth's surface . In that case it's things such as tectonic plate movement,… volcanic activity, wind and water, etc. I'm not too good at this, but I will try my hardest to explain. Many forces act as the earth spins and orbits our sun, but closer in the moon orbits the earth. The earth not only pulls on the moon, but the moon pulls on the earth slightly, water is affected more as it flows and this is how tide changes are usually caused. Then there is the spin of the earth, the spin of earth is perfect, but any faster and it would cause a sort of an oval shape due to the centrifugal forces acting on the planet. If you get a small sphere and polish it as smooth as you can, if you enlarge it to the scale of earth, the ball you polished would have hills and trenches as deep and high 20 to 40 meters, and this done with diamond polish. Oh, and if a meteor or asteroid strikes, this could change that part of earth. Did you know that when China finished building its dam, water level rose and the earth gained time by (if I remember correctly) 0.00002 seconds. ( Full Answer )
The shape of the Earth is actually a rather complex figure called ageoid, which just means "Earth-shaped". It's roughly an ellipsoid(which is itself pretty close to a sphere), but one where thesouthern hemisphere bulges just a tiny more than the northern one,making it very slightly pear-shaped (with… additional bulges invarious places). ( Full Answer )
Shape of the earth and the moon is round (spherical) . AlthoughSceintists have differtent onpinion about the shape of the space,it is believed that shape of space is flat (according toFriedmann-Lemaitre-Robertson-Walker (FLRW) model ).
the earth is a sphere but if you look at it as a 2d shape it is a circle
Plate tectonics are what each continent is on. They move and are continuing to move today. It has to do with the earth's shape because the plate tectonics move the continents around.
All three are globe-like due to internal gravitation forces. Thoughthe Earth is an Oblate Spheroid, and not a perfect sphere.
Now you can look at pictures - in the old days you could watchships disappear over the horizon.
