#Facts about the Earth#
Earth is our home. It is home to many not just humans along
but plants, animals and other organisms who live this earth. But there are many
things that we do not know about the earth.
Earth is the third planet from the Sun. The Earth is the only planet in our solar system not to be
named after a Greek or Roman deity. The Earth was formed approximately 4.54
billion years ago and is the only known planet to support life.
Friends! You will not know some things related to
the earth. We are going to tell you such things related to the earth, which you
have never heard of before.
1. The day was not always 24 hours.
Now I ask you how many hours there
in a day are, then you will say that there are 24 hours. This is a simple
question, but friends were not always like this. About six crores years ago,
there used to be only 21 hours and 54 minutes in 1 day, in fact, due to the
tidal waves of the moon, sun and other planets coming into the sea there is a
slight change in the Earth's orbit and in 100 years The time of one day
decreases by 1.7 milliseconds.
2. Increased heat!
Friends, the heat on
Earth is constantly increasing. Scientists believe that from today on wards 100
million years later, our Sun will be 10% brighter and warmer than today. After
400 crores, the heat will increase so much that the sea water will turn into
steam. After 4.5 hundred million years, the Earth will turn into a big desert
like Mars and the sun will have taken such a terrible form that perhaps
Mercury, Venus and our moon will be over.
3. Earth is not completely round.
Since childhood we have been taught that the
Earth is round, but friends you might not know that the Earth is not completely
round. It is slightly flattened on its poles, or it can be said that it is
slightly more rounded in the middle. In fact, the Earth rotates on its orbit
towards the equator at such a speed that the shape of the earth has become as
if the ball was hit with force.
4. Tallest Mountain:
do
you know? Mount Everest is the tallest mountain on earth because the height of
the mountain is measured from the sea level. If we measure the height from the
womb of the Earth, Mount Chimborazo is the highest mountain.
5.Orbit and Rotation
The Earth
makes a complete rotation on its axis once every 23.9 hours. It takes Earth
265,25 days to complete one trip around the Sun – year. For calendars to
maintain their consistency with this orbit, every 4 years one day is added –
this is called a leap day – as well as a leap year.
6. Earth’s surface is covered in water
When astronauts first went into the space, they looked back at the Earth with human eyes for the first time and called our home the Blue Planet. And it’s no surprise. 70% of our planet is covered with oceans. The remaining 30% is the solid ground, rising above sea level.
Only 3% water
of the earth is fresh, rest 97% salted. Of that 3%, over 2% is frozen in ice
sheets and glaciers. Means less than 1% fresh water is found in lakes, rivers
and underground.
