Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.

A Cozy Blanket Around The Earth There are layers of different molecules, temperatures, and pressures. Overall, the atmosphere is made up of a few main molecules. The air above you is made of 78% nitrogen (N2), 21% oxygen (O2), 0.9% argon (Ar) and 0.04% carbon dioxide (CO2).

The earth's atmosphere is made up of about 78% nitrogen, 21% oxygen and the last 1% are other gases including argon, carbon dioxide and water vapor.

The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.

Compared to the Earth's early atmosphere , the modern atmosphere contains: less water vapour. less carbon dioxide. more oxygen.

Air on Venus The atmosphere of Venus is made up mainly of carbon dioxide, and thick clouds of sulfuric acid completely cover the planet. The atmosphere traps the small amount of energy from the sun that does reach the surface along with the heat the planet itself releases.

Earth's atmosphere is a thin layer of gases that hover above our planet's surface. The atmosphere provides us with oxygen to breathe, shelters us from solar UV radiation, and warms Earth's surface via the greenhouse effect.

The Earth is wrapped in a blanket of air called the 'atmosphere', which is made up of several layers of gases. The Sun is much hotter than the Earth and it gives off rays of light energy that travel through the atmosphere and reach the Earth's surface.

Earth's Atmosphere: Earth's atmosphere, which is composed of nitrogen, oxygen, water vapor, carbon dioxide and other trace gases, also consists of five layers. These consists of the Troposphere, the Stratosphere, the Mesosphere, the Thermosphere, and the Exosphere.

The atmosphere is all the air above the surface. The weather is a state of the atmosphere, described by the wind, temperature, humidity, rain, cloud, etc. Weather happens in the atmosphere.

What is Mars' atmosphere made of? The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide. Here's a breakdown of its composition, according to a NASA fact sheet: Carbon dioxide: 95.32 percent.

So what is air, exactly? It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.

In contrast, the gas giant atmospheres are composed mostly of hydrogen and helium. The atmospheres of at least the inner planets has evolved since they formed. This is clearest for the Earth. The Earth's original atmosphere was probably similar to Venus in composition, consisting of carbon dioxide and nitrogen.

Atmosphere. One of the main components of Earth's interdependent physical systems is the atmosphere. An atmosphere is the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.

The atmosphere contains the gases that surround the terrestrial and maritime biomes within the biosphere. In the atmosphere the main elements are hydrogen, nitrogen, oxygen and carbon. Oxygen is the most prominent element and allows for the organic life, such as humanity, to exist on the Earth.
