Hi guys 👋 in this blog lets see some interesting facts about earth 🌎 
EARTH IS UNIQUE :
The earth along with the sun and the remaining planets of our solar system, originated around 4.8 billion years ago from dust particles which agglomerated gradually. At that time the young earth was bombarded by countless mateorites from space. The earth's interior was molten and volcanoes erupted constantly. But over millions of years, the earth's surface cooled down around 3.8 billion years ago the temperature decreased to but 100 degree Celsius and the earth crust slowly started becoming solid at this time the gaseous cover on the earth was mostly made up of water vapour. 
HOW DOES EARTH ROTATE :
One rotation of the Earth takes one day. If a 12 noon the sun is at the highest point in the sky then after 24 hours it will come back again to the same position it was the Babylonias who first divided the day into 24 hours they could have Counted the hours from 1 to 10 then to 20 and so on but instead the calculated from 1 to 60 then to 120 and so on. For this reason time is divided into parts of 60 ( 1hour has 60 minutes 1 minute has 60 second ) or in parts of 6 ( one day has 24 hours i.e., 4×6 hours ). 
WHY EARTH ROTATES :
At the beginning of the universe they were only gas and dust particles in space. since objects with a physical mass have a mutual attraction the dust particles agglomerated gradually to form larger bodies such as stars and planets these bodies started rotating the movement they collided. After many collisions the rotations got added up. For this reason the planets including the earth or in a constant state of motion in the respective orbits.

HOW DAY AND NIGHT OCCURS :
The rotation of the Earth on its Axis causes the alternation of the day and night. The earth also revolves around the sun. As a result of both these movement, the earth does not get continuous light from the sun. This means when countries such as India faces the sun and has a bright day, the area on the other side of the globe, such as the United States, or immersed to complete darkness.

WHAT HAPPENS IF NO WATER IN EARTH :
Without water there would be no animals or plants which carry out photosynthesis and release oxygen under consequently the oxygen content in the atmosphere would go down. Without a large water bodies the temperatures of the sunlit areas and those away from the sunlight or the change drastically.
