How the
shape of the Earth?
The shape of the planet Earth
is very similar to the oblate spherical (oblate spheroid),
a depressed circle
on the orientation flat poles causing bulging at the equator.
This happens
because the distended rotation of the Earth,
causing the equatorial diameter
greater than 43 km in diameter from pole to pole.
The average diameter of the
sphere of Earth is 12 742 km,
or approximately 40,000 km / π. Because the meter
was originally defined as 1 / 10,000,000
the distance between the equator to
the North Pole through Paris, France.
Local topography varies slightly from the ideal shape of a smooth sphere,
even
on a global scale, this variation is very small.
Earth has a tolerance of about
one in 584, or 0.17%
compared to a perfect sphere (reference spheroid), which
is more smooth
when compared with a tolerance of a billiard ball, 0.22%.
Largest local deviations in the surface of the Earth is Mount Everest (8,848 m
above sea level) and the Mariana Trench (10,911 m below sea level).
Because
the bulging equator, part of the earth is farthest away from the
midpoint of the
Earth is actually Mount Chimborazo in Ecuador.
The process of endogenous
natural / endogenous energy is energy that comes
from the Earth in the Earth.
Workers are building the endogenous nature
of Earth's surface. Exogenous
natural force of extraterrestrial origin and destructive.
So the force that
makes a wide variety of relief on the face of this Earth as
we know that the
surface of the Earth in which we live is made up of various
formations such
as mountains, valleys, hills, lakes, rivers, and so on.
The existence of these
formations, causing the Earth's surface becomes uneven.
Formations are known as
the relief of the Earth.
In the past,
people thought the earth was flat like a plate.
They are afraid of falling over
the edge.
Now, we know that the Earth is almost like a ball.
Measurements made
by the satellite showed that
the earth was measured 43 km thicker in the
middle,
compared to its thickness from pole to pole.
As with most people, the
earth slightly protruding around the waist!

How big the
size of the earth?
Earth's
circumference of about 40,000 miles.
you have to fly in a jet plane for 30
hours to be able to travel that far.
Compared to several other planets, Earth
is smaller.
Jupiter fly around in a jet aircraft would take 14 days.
