Earth's shape is described as an "oblate spheroid", in other words, a very slightly flattened sphere.
It's rotation. Earth would naturally have achieved hydrostatic balance (perfect sphere) as it cooled. Eons of spinning on it's axis has slightly flattened the poles, giving earth a very slight "oblate" shape as opposed to a perfect sphere.
The shape the Earth is a slightly oblate spheroid.
what is the internal and enternal changing in the earth
It is true. Earth moving around the Sun, WITHOUT any other objects in the Universe, and WITHOUT considering General Relativity, would be an unchanging ellipse. However:* As a result of the warping of space-time (General Relativity), the periapsis will change over time. That is, the ellipse, while maintaining its shape, will change its position in space. * Other objects, mainly in the Solar System, pull on the Sun and on the Earth. This will actually change the shape of the orbit over time. The effect, in both cases, is very small, at least in the short term.
the shape of the moon is caused by the movement of the earth. Earth's shadow causes the shapes. As the earth moves, so does its shadow, creating different shapes (phases).
the globe
Globe is the best representation of the earth because it shows the shape of the earth, which is spherical and it makes it easy to show how the earth revolves and rotates.
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.
is is true
A map is not a three dimensional representation of earth's surface. The best three dimensional representation of earth's surface is a globe or a topographical map.
use your brain!! if its a small one then yes it would be useful but if it was a big one it would be hard to carry around.
is is true
It is pretty close.
The shape of the earth is considered to be an oblate spheroid or ellipsoid and not actually a true sphere. The size of earthâ??s surface is 361.132 million square kilometers which is equivalent to 139.43 million square miles.
a physical map
Many of the processes that changed the Earth in the past are the same processes that operate in the present.
A globe is the most accurate representation of the earth.
