why is nitrogen important in atmosphere?
483053
Nitrogen (N) is one of the building blocks of life: it is essential for all plants and animals to survive. Nitrogen (N2) makes up almost 80% of our atmosphere, but it is an unreactive form that is not accessible to us. Humans and most other species on earth require nitrogen in a “fixed,” reactive form.

Nitrogen gas is only slightly lighter than air and readily mixes with air at room temperature. Cold vapors are more dense and will settle.

['Nitrogen gas and ammonia are both being cycled. ... ', 'Plants, decomposers, animals, and nitrogen-fixing bacteria are all abiotic factors in the nitrogen cycle. ... ', 'The cycle is important because it is used to make complex organic molecules and it is important for the nutrients cycle. ... ', '7) Plants use nitrogen in the form of...']

The major contributor to the dissolved nitrogen found in rain is the burning of fossil fuels in the atmosphere. It comes from electric power generators and release of nitrogen oxides from the power plants in the factories.

Ammonia is present in soil, water and air, and it is an important source of nitrogen for plants. Nitrogen promotes plant growth and improves fruit and seed production, resulting in a greater yield. It's also essential for photosynthesis, which is the process in which plants convert light energy into chemical energy.

Nitrogen is not stable as a part of a crystal lattice, so it is not incorporated into the solid Earth. This is one reason why nitrogen is so enriched in the atmosphere relative to oxygen. ... Thus, over geological time, it has built up in the atmosphere to a much greater extent than oxygen.

The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun's dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.

Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation. Up to about 80 km, the composition of atmosphere is highly uniform; therefore, the term homosphere is applied.

Nitrogen cycle. Nitrogen from the air is needed for the production of proteins. As animals eat plants so they receive the nitrogen, which is released and recycled by decomposition of dead organisms.

In addition, the atmosphere contains substances that are essential for life, including carbon, nitrogen, oxygen and hydrogen. The hydrosphere - this consists of those parts of the earth system composed of water in its liquid, gaseous (vapour) and solid (ice) phases.

The Earth's atmosphere is the relatively thin layer of gases that surround the planet. It provides us with the oxygen we need to stay alive. The three most abundant gases (the ones with the highest percentages) are all elements: 78% nitrogen, N.

The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. ... The atmosphere also helps to sustain life of Earth. It provides oxygen for humans and animals to breathe, and carbon dioxide for plants.

The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases. The most abundant gas in the atmosphere is nitrogen, with oxygen second. Argon, an inert gas, is the third most abundant gas in the atmosphere.
571940
The atmosphere is composed of a mix of several different gases in differing amounts. ... Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

The atmosphere is essential for life for the following reasons: (a) Oxygen which is essential for the survival of all living organisms is present in the atmosphere. ... (d) The atmosphere acts as a protective blanket for the earth by blocking the harmful UV rays from the sun.

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.
