A new week has arrived and that means some facts about the Earth.
If you went soaring through the atmosphere in a hot air balloon, you would find it harder to breathe the higher you went as the atmosphere gets thinner.
The mixture of gases in the atmosphere has taken over 4.5 billion years to evolve, around 99% of the atmosphere is made up of oxygen and nitrogen, the remainder is tiny amounts of other gases.
The force of gravity is not even all over the Earth, a person weighing around 150 pounds at the equator would weigh 151 pounds at the North Pole.
The part of the Earth that has life on it is called the ecosphere.
The length of a day on Earth is increasing by 17 milliseconds per century.

Dearest Jo-Anne,
As long as we live, we will not fully grasp the mystery of our planet!
So–called scientists also are just guessing. Nobody was there when the universe got created.
Hugs,

You are so right I have always wondered how the hell do these scientists know isn’t all just as you said guess work.
Oh, some are so arrogant that they presume the majority of us is too stupid…
