10 Interesting facts about the earth

A myth- universe center

If I ask who is the center of our solar system, it's our sun. We all know this. But there was something different saying in the past. Some scientists believed that our earth was the center of the universe. They named it the Geocentric model. But later on, a scientist named Nicolas Copernicus presented a heliocentric model that proved the Geocentric model false.

Slowing down

The rotation of the Earth is gradually slowing down with a rate of 3.78cm/s in the year. This is due to the far going moon. You won't believe millions of years ago the moon was so close that an average day on Earth was of 6 hours. Think about how on earth you would be doing all your activities if you were there at that amazing time.

Moon a part of the earth

Moon is probably a small chunk of earth. Yeh, you read it correctly.    About 4 billion years ago when the earth was still just a baby she felt very lonely will revolve around the sun. Then one day a gigantic space rock Theia collided with our earth. Probably due to this, a big chunk of our planet got separated from it. Which is currently known as the moon. After that our earth never felt lonely. Hh happy ending.

Magnetic field changing

The earth's magnetic field is changing. The main reason for the magnetic field is our core contains Nickel - Iron and there is a pretty fast axial rotation.
Since the 19th century, the northern magnetic pole has shifted to 685 miles towards the westward. It is quite alarming. 

Earth is gold

If all the gold present inside the earth could be extended, it would be enough to cover the entire surface of our planet in a 2- foot layer of gold. And imagine what, each of us can get 9 pounds of this Treasure if distributed equally.

It is estimated by the Radiometric dating technique. The oldest rock found is about 4.54 billion years old.

Variability in temperature 

Earth's average temperature is about 16°c. But there are some places where temperature differs from normal. On Sep 13, 1922, a record highest temperature was recorded at Alazizia.
And on July 21, 1983, at Vostokstats, Russia lowest temperature -89.2°c was recorded on Earth.

Varying gravity

Gravity on Earth isn't the same at every part. This is because our earth is not a perfect round, rather it is like a squashed sphere. So it's mass is a little irregular which can differ acceleration due to gravity at different places. That is g.

Not a mythological name

If you study different planets name in our solar system you will get to know that leaving earth all the other seven planets were named after Roman gods and goddesses.
