Answer : The Earth is not a sphere. It is slightly flattened at the North and the South Poles and bulge in the middle. Such shape is known as
a Geoid
.
What is the shape of the Earth answer?
The Earth is an
irregularly shaped ellipsoid
.
While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid.
What is the shape of the Earth for Class 3?
The shape of the Earth is
geoid
.
What is the shape of Earth in simple words?
Shape. Earth’s shape is
a spheroid
: not quite a sphere because it is slightly squashed on the top and bottom. The shape is called an oblate spheroid. As Earth spins around itself, centrifugal force forces the equator out a little and pulls the poles in a little.
What is Earth’s true shape?
Since the Earth is flattened at the poles and bulges at the Equator, geodesy represents the figure of the Earth as an
oblate spheroid
. The oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.
What is the Globe Class 6?
A globe is
a spherical figure which is a miniature form of earth
. It gives us a three-dimensional view of the whole Earth by showing distances, directions, areas, etc. … The globe provides 3-D (three-dimensional view) of the entire Earth. The latitudes and longitudes are shown on the globe as circles or semi-circles.
What are the two parts of the earth Class 3?
In the centre of the Earth is a solid ball of melted metals. It is called the core. The
part between the crust and the
core is the mantle. It is also very hot.
Why do we call the earth our home Class 3?
We call the earth our home . why ? Ans.
Because it is the home of all living beings
.
Is Earth a geoid shape?
A geoid is
the irregular-shaped “ball”
that scientists use to more accurately calculate depths of earthquakes, or any other deep object beneath the earth’s surface. … If Earth were a perfect sphere, calculations of depth and distances would be easy because we know the equations for those calculations on a sphere.
Who named planet Earth?
All of the planets, except for Earth, were named
after Greek and Roman gods and godesses
. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’.

What is the size and shape of the Earth?
It is
an oblate spheroid
. It’s flattened at the poles and bulges at the equator. The Earth is 12,756km at the equator and 12,714km from pole to pole. We round this up to 13,000km.
Is Earth egg shaped?
New photos taken from Voyager 2 show that
planet Earth is oval in shape
, resembling an egg, and not spherical as originally thought. … From this distance, Earth appears spherical, as only one portion of the Earth’s surface is visible at a time.”
What causes the Earth’s Oblateness?
This is the result of
the hydrostatic balance between the dominant gravitational force
, which wants to pull the Earth into a spherically symmetric configuration, and the centrifugal force due to Earth’s rotation, which wants to expel mass away from the rotating axis but in the end only manages to modify the Earth into …
Who invented globe?
The earliest surviving terrestrial globe was made in Nürnberg in 1492 by
Martin Behaim
, who almost undoubtedly influenced Christopher Columbus to attempt to sail west to the Orient.
