The lesson today is about the atmosphere.
The ozone layer blocks out ultraviolet light so that we don't have to.
We live in an ocean of air called the atmosphere.
The atmospere is thin yet thick enough to breathe.
10 kilometers is thick enough for living things, including us to breathe.
The atmosphere here is ten kilometers, which is very thin.
The atmosphere acts like a blanket that keeps the world warm and protects the planet from comets plus meteors.
The Moon was unable to retain most of its gases.
The troposphere is the lowest and thickest layer of the atmosphere.
The lower the atmospheric pressure, the higher we are.
The pressure of the atmosphere changes depending on the location.
Death Valley is the lowest place in North America and there is so much atmosphere overhead there.
The pressure is much lower in the airplane so ears pop as a result of this lower atmospheric pressure during flights.
There is no atmosphere in outer space, and the lunar as well as the Mercurian, Martian, and Plutonian atmospheres are very thin.
The solar, Venusian, and Jovian atmospheres are very thick.
The Saturnian, Uranian, and Neptunian atmospheres are very thick just like the Titanian atmosphere.
The atmosphere is thin yet heavy.
We live in the troposphere.
The atmosphere is thin yet thick enough to keep us warm.
It gets colder and colder as the we go higher up in the atmosphere, or the air.
The thinner the atmosphere gets, the colder it gets just like an
The Greenhouse Effect keeps Venus and the Earth warm.
The Greenhouse is covered with layers of gas.
There is a layer of glass that keep Venus and the Earth warm.
Without the Greenhouse Effect, the Earth would be very cold at night and very hot during the day just like on the Moon and Mercury.
Sulfuric acid from the sky is an air pollution that is found on Venus.
Acid rainfall is also on Venus.
The troposphere is only ten kilometers thick.
The troposphere is a part of the atmosphere where we have weather so we have clouds and rain.
There is more information on the Solar System's, Galactic, and Universal Atmosphere on the World Wide Web, the University of Google.
A place on the moon does not have enough gravity to hold an atmosphere so we have to take our own just like we would have to in outer space.
The next lesson is about oxygen.
You have given us oxygen to breathe.
Swimming is good exercise, which requires breathing a lot of oxygen.
We breathe all day, all night, all of our lives.
Lungs are inside of our chests.
There is no free oxygen on Mars.
When we breathe, our lungs fill up while our diaphragm goes down.
Our lungs are full of tiny passageways like sponges.
Lungs have just as much surface area as a tennis court.
Right lung is bigger than left lung.
The right lung is divided into three parts and the left lung is divided into two.
The right lung is bigger than the left lung because we have a heart.
Muscles can't do any work without the lungs.
Respiration is when we get the air we need from the oxygen we breathe.
There is cellular respiration which is a respiration that goes on inside of the cell.
ATP stores energy and then releases it.
The bag holds air just like our lungs do.
The diaphragm cooperates with our lungs so that we can breathe.
When we breathe in, the diaphragm pulls down and air rushes into our lungs.
Breathing is critical.
Mucous is the slime that we have in our nose and our lungs.
I should not smoke as it is not healthy.
There is a chemical formula for cellular respiration.
Fish can breathe under water with their gills.
We cannot breathe under water without oxygen.
We get sick and/or allergic reactions from stuff in the air.
Every time we breathe, we breathe over ten quadrillion molecules.
There is more important on the atmospheric oxygen on the Internet, The University of Google.
Thank You, God, for these lessons.
