FACTS ABOUT THE EARTH

1. The earth rotation is gradually slowing:
   This deceleration is happening very slowly, ag approximately 17 milliseconds per hundred years, though the way at which it occurs is not perfectly uniform. It has an effect of lengthening our days, but it happens so slowly that it could be as much as 140 million years before the length of the day will increase to 24 hours.

2. Earth magnetic field is very powerful:
   This phenomenon is caused ny the nickel-iron core of the planet, coupled with its rapid rotation. This field protects the earth from the effects of solar wind.
   

3. The Earth is the Densest planet in our solar system:
   This varies according to the part of the planet, for example, the metallic core is denser than the crust, the average density of the earth is approximately 5.52 grams per cubic centimetre.

4. The Earth is the only planet in our solar sytem where water can be present in all three states, Solid, Liquid and Gas

5. Earth's inner core has a temperature between 5400 and 6000 degrees Celsius, making it hotter than the surface of the sun ( 5500 Celsius)
