Homguy:
you said , and its generally known that pressure drops with Height , what do you mean by " Planes do not fly above the Troposphere because they can't withstand pressure at that height, what do you mean? Or are you referring to negative pressure?

rita25:
the trothosphere will mix with the smellosphere and you will hear who mess ophere?

YesIam:
Well, we've gone back and forth all for knowledge, and its good. I did my MSc thesis on Air quality management.
You did great bro, keep it up.

Segadem:
Atmossphere is divided into 5, which one the plane will fly beyond?

Angama:
Who made the atmosphere? You?

menesheh:
Not me and i don't know how it came about. Do you?

rita25:

MrBONE2:
pls will the mess ophere induced "BLACK HOLE or Deplete Ozone Layer".

mrphysics:
tells us more about the existence of a supreme being. I so much believe HE exists, the world and the human body is so complicated that it points to the fact that God exist. very soon, I will educate us on the layer of the atmosphere.

menesheh:
Why must there exist a supreme being? Why must be a who instead what causes this or that? Try and compare the two explanations (religion and scientific method) of why we are here.

"I will educate us" evangelism?

Design or god is not recognize by complexity. We see complexity taking place naturally. Sand dune appears complex but we see them form by the wind action.

mrphysics:
because you are still allowing your instinct to control your judgement. my dear, let's face the truth, THEY IS GOD. though not trying to derail the thread. hope you are good sir

mrphysics:
Am a physicist(Geophysics/Meteorologist), I put up this writing to educate my fellow nairalanders, I hope u enjoy it.
feel free to ask your questions after reading, and ignore any typographical error
Let's get started



10 THINGS YOU NEED TO KNOW ABOUT THE ATMOSPHERE


1: WHAT CAUSES WIND AND WIND FLOW: The cause of wind is the differences in pressure and temperature of a given area. Winds always flow from regions of cooler temperature (high pressure) to regions of warmer temperature (low pressure). The greater the differences in temperatures or pressure, the greater the wind speed


2: WHY DOES AIR PRESSURE DECREASE WITH HEIGHT
The pressure at any level in the atmosphere may be interpreted as the total weight of the air per unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than similar surface at lower levels. Example, there are few air molecules at 50km than are found at 12km, which is why the pressure is less at 50km

3: WHY ARE GASES SUSCH AS CARBON DIOXIDE, NITROUS OXIDE, METHAN AND CFC CALLED GREEN HOUSE GASES
They are called greenhouse gases because they are able to absorb and emit infra-red radiation.

4: WHY IS IT DANGEROUS TO SEEK SHELTER UNDER A TREE DURING THUNDERSTORM
It is very dangerous to seek shelter under a tree during thunderstorm because when lightning strikes, it delivers an enormous force of electrical energy that can break off branches or even split trunk of the tree.

5: THE HIGHER YOU GO, THE COOLER IT BECOMES? TRUE OR FALSE?
It is true in the layer of the atmosphere where we live. The earth’s atmosphere is divided into five layers: TROPOSHERE, STRATOSPHERE, MESOSPHERE, THERMOSPHERE and EXOSPHERE. The statement is true only in TROPOSHERE (0-15KM above sea level) and in MESOSPHERE. A process called LAPSE RATE (the decrease in temperature with height). Outside these two layers, inversion occurs (the higher you go, the hotter it becomes)

6: DOES PLANEs FLY BEYONG THE TROPOSHERE
Negative, our planes does not fly beyond this layer of the atmosphere, perhaps because it cannot withstand the pressure of the nearest layer of the atmosphere. Our planes rarely reach 14KM.

7: WHICH LAYER OF THE ATMOSPHERE DOES RAIN OCCUR?
I need to state clearly that all our rain falls happen within our layer of the atmosphere we live in (TROPOSPHERE), outside this layer of the atmosphere, they EXIST no rain or rainfall.


8: WHAT IS NOWCASTING?
The forecasting of weather within the next six hours is often referred to as nowcasting. In this time range, it is possible to forecast smaller features such as individual showers and thunderstorm with reasonable accuracy, as well as other features too small to be resolved by a computer model.

9: WHAT IS THE IONOSPHERE?
The ionosphere is the layer of earths atmosphere that is ionized by solar radiation. The ionosphere contains plasmas and is made up of three layers, the lowest is called D-LAYER(75-95KM), E-LAYER(95-100KM) and the F-LAYER(150km upwards).

10: HOW DOES THE IONOSPHERE INFLUENCE AM RADIO TRANSMISSION DURING THE DAY AND AT NIGHT
Distant AM radio stations are better received at night because the ionosphere that reflects AM stations is protected from ionizing radiation and ionized particles from the sun. when the sun comes up, it heats up the air, helping to make a part of the air that can reflect radio waves that comes from an AM radion station.

alatbaba1:
Well OP, some of ur facts r true but some r lies. Plane flies above 14km. Pressurized aircraft fly up to 35km be it civil aircraft or military aircraft. Military jets fly at that range too. Rockets and spaceships fly above 35km.

To add to some point. Most of our weather activities happens at 14km and below. Rain, snow etc.

Osirimononaye:
Honestly I Love Your Write Up...Very Educative
*No End Time*..

jacoik:
in conclusion pls!!! what should I do with this now. when d natural things Baba God created to occur on it appointed time human don turn upside down . I dey watch una one by one

Dollyak:
A few corrections though .

4 The reason why it is very dangerous to seek a shelter under a tree is not because it breaks off (they rarely do due to grounding effect). The main reason is because trees are often the tallest object relative to any pointy other object, which means trees are often susceptible to lightning strikes (Electric field is strongest at the tallest pointy tip of a conductor). This means in case of strikes you are at lower earth potential compared to the tree due to human being made out of saltwater and thus the strike will always transfer to you more often that not.

6 This is not true at all as planes are pressurize to deal with it. The main reason why Planes will not fly in stratosphere is mainly due to heat reasons and turbulence (lower aerodynamic efficiency). As you probably know, in troposphere the atmosphere is transparent to the sun's energy and is instead heated from below the earth's surface.

menesheh:
Nice one.


Bringing scientific knowledge to the doorpost of the unscientific Nigerian youths who still think that those natural phenomena are being propel by the hand of god.

erusen:
why are you obsessed about God and religion obsession is a disease,na because say i like you ni make i dey tell you ow

menesheh:
I hate it when people use that name freely to engage in immoral acts. why am i not obsessed with Santa Claus and leprechaun. if people started extorting money and engaging in evil acts with sango, i will despise such name, not that obsessed with anything.

thanks for the like.

Himmaculate:
Just accept the fact that God is Dead, and Science killed it.

jacoik:
I just pray the living GOD to have mercy on ur soul because u are lost!!! may the blood of the one who died on the Calvary wash away ur sins amen

mrphysics:
hearing it for the very first time that military jets fly at 35km? do you know the atmosphere you are talking about?? pressure is not the only thing that determine how far flights gets to. the constituents of that layer also matters mostly.

airmirthd1:
Hummm......Great!! But some people too dey brag......




When you con know am before nko......make we run??
