The atmosphere of Earth is composed of a mixture of gases. The major elements in the atmosphere are oxygen and nitrogen. However, other gases are present in minute amounts. Water vapor and argon also play important roles. They are present in small quantities and are present at low concentrations. The gravity of the Earth is what keeps these gases in suspension. Therefore, if you want to know more about the atmosphere of Earth, it’s worth reading this article.
The atmosphere of Earth is made up of different layers. The lowest layer, or troposphere, is the warmest and is responsible for most weather on Earth. As the atmosphere increases in height, it becomes thinner. As a result, the pressure of air decreases. For example, the air pressure at sea level is 14.7 pounds per square inch. This is relatively high, so we can’t breathe it. But at high altitudes, it’s much lower.
The atmospheric composition of Earth is composed of a variety of gases. Some are noble, such as argon and hydrogen. Others are trace gases. This article will discuss the various gases that make up the atmosphere of Earth. Once we know the major elements in the atmosphere, it’s time to understand how they interact. The different parts of the atmosphere affect each other. Moreover, it’s important to know how they influence each other.
The Earth’s atmosphere transmits electromagnetic radiation. Its molecules absorb different wavelengths. Oxygen and nitrogen absorb the shortest wavelengths. In addition, they absorb many photons above 700 nm. The molecule absorbs the energy of the photons, thus heating up the atmosphere. The other way that the atmosphere cools down is by emitting the same wavelengths. The atmosphere also regulates temperature by absorbing and emitting radiation.
The Earth’s atmosphere is a layer of gases that surrounds the planet. It was formed about 3,000 million years ago and is continuously changing. At this time, life developed in the environment. Unicellular organisms evolved the photosynthetic system that converts carbon dioxide into oxygen and sugars. The evolution of these organisms significantly increased the oxygen levels of the atmosphere. And now, the planet is covered with the atmosphere.
The Earth’s atmosphere is the largest layer of the Earth’s atmosphere. The thermosphere absorbs most of the harmful radiation from the sun. The exosphere represents the boundary between the Earth’s atmosphere and space. The atmosphere of the planet was formed about 3,000 million years ago. About two billion years later, the photosynthesis system had evolved in humans, which dramatically increased oxygen in the atmosphere. The photosynthetic system allowed complex cells to form. This led to the development of the thermosphere.
In general, the atmosphere of Earth is comprised of three main gases: oxygen, nitrogen and argon. In fact, these four gases make up seventy percent of the atmosphere. Some of them are noble, while others are volatile and unstable. In the past, atmospheric oxygen was abundant in the atmosphere. Its concentration varied from 10 ppm in the coldest parts of the atmosphere to five ppm in the hotter parts of the atmosphere.
The atmosphere of Earth is composed of several layers. The uppermost layer is the troposphere, which is tens of kilometers above the surface. The atmosphere has no definite boundary with outer space. At 120 km, the atmospheric effect becomes noticeable and is observed. It is not known whether the atmosphere of Mercury is similar to the one of Earth. If the two gases are not completely identical, the Earth’s atmosphere is thin and has little oxygen.
The Earth’s atmosphere is layered, with the troposphere being at the surface. In contrast, the stratosphere is about 50 km above the surface. It extends up to 400 miles. It is the third layer, which is called the exosphere. A large part of the atmosphere is nitrogen, while the rest is mainly oxygen and argon. There are other molecules called noble gases, and some of them are present in the atmosphere.
