Outgassing from volcanoes formed the Earth's original atmosphere.
Later green plants converted large amounts of carbon dioxide in the
atmosphere to create the modern atmosphere with roughly 20% oxygen,
80% nitrogen, and tiny amounts of other gasses.
A barometer measures atmospheric pressure. A link is provided to the Wikipedia article on the barometer, and you can find that link below.
No. The physics is based in the way light is scattered in the air,
and it is discussed in the question, "Why is the sky blue?" That
question is linked below. AnswerIf that were true, there wouldn't
be any blue skies in Kansas. And there are!
Actually, the coloring in the sky that you observe is a r…
The atmosphere is a gaseous envelope (with suspended liquids and
solids) that surrounds the Earth and is held in place by gravity.
The atmosphere is very thin compared to the size of the Earth. A
virtual vacuum exists above an altitude of 100 miles (160 km), and
breathable air is only about 6 miles …
Most of earth's atmosphere is in the lowest layer, the troposphere.
Thus most of the gases are within 15 km of the Earth's surface.
The aurora is a glow observed in the night sky, usually in the polar zone. For this reason some scientists call it a "polar aurora" (or "aurora polaris"). In northern latitudes, it is known as "aurora borealis" which is Latin for "northern dawn" since in Europe especially, it often appears as a redd…
Normal Atmospheric Pressure at Sea Level
'Standard' atmospheric pressure is defined at sea level as 101,325 pascals (newtons per square metre), 760 millimetres of mercury or about 1 bar (1000 millibar). These numbers are equivalent values using different measurement systems. Naturally air p…
No, it has changed over time. The original atmosphere of the Earth
was mostly carbon dioxide with some water vapour, ammonia and
methane, and was probably formed by volcanic outgassing. Living
things introduced oxygen, and were one of the causes of reduced
carbon dioxide. The ammonia then reacted wi…
Weather ToolIt is called a radiosonde (or sonde for short) and is attached via a long string (and parachute for the descent) to a weather balloon that is filled with either hydrogen or helium. They are launched globally at least twice daily 00z and 12z (GMT). In the US, they can also be launched at …
Carbon Dioxide keeps the atmosphere warm by absorbing infra-red heat (from the sun) rising from the warm earth's surface. This heat remains in the atmosphere heating other greenhouse gases and even heating the earth's surface again. This is called the greenhouse effect.

The earth's atmosphere is made of mostly nitrogen (~78%) and oxygen (~20-22%), with some highly variable amounts of humidity (i.e. water), and trace amounts of other elements, primarily: argon (9340 ppm) andcarbon dioxide (400 ppm)neon,helium,methane,krypton, andhydrogen
Barometric pressure is usually read and rated in millibars of
atmospheric pressure. A standard day at sea level, would be
29.9 on the barometric scale. That is, neither a high or low
pressure in the area and generally sunny.
Mercury is the smallest of the eight planets, and is the only one not to have an atmosphere. This is due to its small size and close proximity to the sun.
Multiply atmospheric pressure, about 1 x 10^5 N/mm, times the earth's surface area, about 1 x 10^21 mm , to get 1 x 10^ 26 Newtons or about 25 x 10^24 lbs.
Stratus clouds begin when a warm, moist airmass is forced over a cold air mass, essentially a cold front. This forms the cloud. Eventually, it starts precipitating, which drops all the moisture onto the earth. Then, there's no more cloud afterwards.
It prevents harmful electromagnetic rays from reaching the ground.
These include x-rays and gamma rays.

But too some of those gases, by themselves are de…
The Walker Circulation weakens, which causes the Trade Winds to weaken or even reverse. This causes warm water from the Western Pacific to be moved further east all the way to South America. As a result, cold, nutrient-rich water is unable to be upwelled off the coast.
It is the pedosphere that is the outmost layer of the earth where things grow.
Friction is a part, but only a part, of the reason asteroids usually "burn up" in the atmosphere.When a meteoroid enters the upper atmosphere of Earth, it is travelling at a very high speed; in the neighborhood of 30,000 MPH. As it enters the atmosphere the air in front of it is compressed. When a g…
A blocking high will begin to move when the upper level ridge begins to weaken from a jet max either exiting the apex of the ridge which helps to reduce the amplitude of the ridge by decreasing boundary layer convergence.
The Aurora Borealis is made when storms on the the sun form solar winds, or large streams of charged particles streaming toward the earth.These streams could have upward of ten million megawatts of electrical power. That is enough power to light up Los Angeles. It generally takes about three days fo…

The windiest place on earth is generally regarded as Antarctica.Specifically, it is Dennison Bay on the coast where wind reaches 200 mph.
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level(see the related links for charts)However, barometric pressure also varies widely with…
Standard atmospheric pressure is 101.325 kPa. It can also be quoted
as 760 mm Hg, or 14,696 psi. Many values of atmospheric pressure
are normal, because it varies all the time, but the average at sea
level is 101.325 kPa.
This would be easier to answer with a diagram, but here goes. On a sunny day, air near the ground is warmer because of the heat radiated from pavement, sand, etc. Light from the sky will refract (bend or be redirected) because of the difference in temperature of the air closer and closer to the grou…
