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.

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

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.

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

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

Nice

Educative!

HOW ABOUT WHEN YOU MESS?

Mrphysics, I know all these?

C'mon. I've known these things for about 1,000 years now, so tell me something I don't know.

Op, one day i know say you go make us proud.
May the lord strengthen your knowledge.

Who tehl u say i no no b4



I bet most people don't know Jesus' skin color...

All thanks to science

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

We need to start receiving sense in this country.

Not everything is African metaphysics.

OP, thank u jare.

Facts

hightension . hw was life in carva building?

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.

This is a reminder of what I did in secondary schl.... Thanks... I've completely forgotten everything.. When I ve bin in uni fr 4 years now cramming and pouring... I've mistakenly poured those ones too...

noted

Weldone. Gained something today.

Something educative after a long while

highly informative.

Interesting

nice one op

Knowledge is Power

This can not discourage me from believing in God.The creator of living and non-living.

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

mess??

good
