Atmospheric Sciences

Actually, all gases do this to some extent. This is sometimes called the greenhouse effect, although the physics driving it work nothing like a greenhouse. Without the atmosphere's greenhouse effect, this would be a cold, dead planet with an average temperature well below zero (F). The Earth gets heat from solar radiation, but like all objects, it will re-emit some of this radiation back into space, losing its potential heating effect (what proportion is lost to re-emission varies from substance to substance). Now, the gases in the atmosphere have this same property, so it absorbs some of the energy Earth emits and does the same thing, sending some of Earth's emitted radiation right back to the Earth, which is then warmed because it gets back some of the energy it emits. But as I wrote, some substances are better at doing this than others, and the problem is that the gases you mention are very good at it. If their concentration in tbe atmosphere increases, then the air as a whole also gets better at it, increasing the greenhouse warming effect.

There isn't really a schedule of auroras; they happen when a stream of charged particles from the Sun interact with the Earth's magnetic field. Watch the website at spaceweather.com (see the link below) and look for "coronal mass ejections"; bright auroras often follow about 2 days later. But they sometimes are visible without any warning, because the Sun is CONSTANTLY sending out masses of charged particles.

Both aurorae occur around the polar regions. The Aurora Australis appears around Antarctica and the Aurora Borealis appears around the Arctic.

The Aurora Australis is only visible from the southern latitudes and has never been seen north of the 30 degree line of latitude.

The aurora is associated with solar wind activity and is most prevalent at the peak of the eleven year sun spot cycles, and the three years afterwards.

The best places to see an Aurora Australis in the Australasia region would be Tasmania or New Zealand, away from cities and other sources of artificial light pollution.

Saturn has more moons than any other planet in our solar system

The ionosphere is made up of a layer of the Earth's atmosphere that contains a high concentration of ions and free electrons. It is composed of various ionized gases, such as oxygen and nitrogen, that are affected by solar radiation. The ionosphere plays a crucial role in radio wave propagation and communication.

It would be more accurate to say that lighting is caused by the operation of Coulomb's Law which involves both the attraction of unlike charges, and the repulsion of like charges. When a thundercloud contains a substantial negative charge, the excess electrons in the cloud repel each other. Meanwhile, they are also attracted to the ground.

The atmosphere or feeling within a work of art is often referred to as its mood. This can be created through the use of colors, lighting, composition, and subject matter to evoke a certain emotional response in the viewer. The mood of a piece of art can vary greatly depending on the artist's intentions and the viewer's interpretation.

The layers of the atmosphere are composed mainly of different gases. The lower layer, the troposphere, contains primarily nitrogen and oxygen. The stratosphere is higher up and contains an ozone layer. Beyond that, in the mesosphere and thermosphere, the composition is more variable with gases like oxygen, nitrogen, and helium.

Lighting typically strikes the ground from the sky during a thunderstorm when there is a difference in electrical charge between the clouds and the ground. This can result in a lightning bolt traveling from the cloud to the ground.

These are lines of equal wind speed. They are most often contoured in the upper levels of the atmosphere, especially at the jet stream level. They are important for locating the jet stream and jet streaks within a jet stream

An Aurora Australis or an Aurora Borealis occurs when streams of particles from the sun's solar winds hit the earth's atmosphere at an angle (as can only happen at the poles). These particles interact with the edges of the earth's magnetic field and when they collide with the gases in the ionosphere, the particles glow creating curtains of blue, green and magenta. An aurora is sometimes accompanied by a crackling sound.

Yes, some elliptical orbits are more circular than others. An ellipse has two main characteristics - its eccentricity and its semi-major axis. The closer the eccentricity is to 0, the more circular the orbit is.

it happens when sun's particles have a fusion with earth's particles close to earth, only seen in northern and southern poles because of no light pollution and those are also the magnitude poles

No, it is physically impossible to reach the end of a rainbow because rainbows are actually optical phenomena that appear when light is refracted, dispersed, and reflected by water droplets in the atmosphere.

Outer space is typically considered to begin around 62 miles (100 kilometers) above Earth's surface, where the Kármán line is located. Beyond this point, the Earth's atmosphere becomes very thin and spacecraft are considered to be in outer space.

The Earth has been described as a "big blue marble" from space.

It has also been said to make astronauts realize that there are issues much bigger than the little problems we face daily, and that we are all part of a "bigger picture", if you can excuse the cliche.

The stratosphere is a layer of Earth's atmosphere located above the troposphere and below the mesosphere. It contains the ozone layer, which plays a crucial role in protecting the Earth from the sun's ultraviolet radiation. The stratosphere is characterized by increasing temperatures with altitude due to the absorption of ultraviolet radiation by the ozone layer.

The ionosphere consists of the D layer and F layer. The D layer is located closest to the Earth's surface, while the F layer is situated higher up in the atmosphere. These two layers play a critical role in reflecting radio waves and affecting communication systems.

Because of the Earth's rotation and air streams, it can be faster to travel from west to east. If travel from India to Canada is by airplane, there may not be much of a difference since the jet can only reach certain speeds relative to the air surrounding it.

The white and the blue colors are usually used to represent the light rain and drizzle. The black color on the other hand is usually used to represent heavy rainfall.

Fog forms when the air near the ground cools down to the point where it can no longer hold all of its moisture, causing the water vapor to condense into tiny liquid droplets. This process is often triggered by factors such as cooling overnight temperatures, calm winds, and high humidity levels.

The Earth's atmosphere helps regulate temperature by trapping heat from the sun, thanks to greenhouse gases like carbon dioxide and water vapor. The atmosphere also shields us from harmful solar radiation, with the ozone layer in the stratosphere playing a key role in blocking harmful UV rays. The atmosphere is composed of various layers, with the troposphere closest to the surface, followed by the stratosphere, mesosphere, thermosphere, and exosphere, each playing a unique role in Earth's atmosphere.

The "effective volume" of the Earth's atmosphere is about 4.2 billion cubic kilometers. This figure is the surface area of the Earth (509 million square kilometers) times the "effective thickness" of the atmosphere (8.2 kilometers, or about 27,000 ft). The effective thickness and volume are what the thickness and volume of the atmosphere would be if the entire atmosphere were at sea level conditions.

The actual volume of the atmosphere is considerably greater than its effective volume, as its pressure and density drop with increasing altitude. If we adopt the "Karman Limit" of 100 km elevation as the boundary between earth and space, the volume of the atmosphere would be 100 times 509 million or about 51 billion cubic kilometers. However, the Karman Limit is a non-physical and rather arbitrary boundary.

Carbon dioxide is a gas in the atmosphere that varies between zero and five percent. Its concentration can change due to factors like human activities, volcanic eruptions, and natural processes. Carbon dioxide plays a crucial role in the Earth's carbon cycle and is a greenhouse gas that contributes to global warming.

The density of the Earth's atmosphere varies with altitude, but at sea level it is approximately 1.2 kg/m^3. As you move higher in the atmosphere, the density decreases.

Earth's atmosphere is split up into five layers:

troposhere- 10km

stratosphere- 10-50km

mesosphere- 51-87 (about)km

thermosphere- maximum 500km

exosphere- space begins
