What is so special about nitrogen in the atmosphere

Biology
1 answer:
HACTEHA [7]4 years ago
5 0

Answer:

Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.

Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.

Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.

thousands of years

Explanation:

A delta the size of the Mississippi River will take several thousand of years to form because the process of formation of a delta is geologically controlled.

A delta is a place where  river enters or drains into the sea with many mouth or outlets.

Deltas are depositional terrain full of dis-tributaries.

  • For a delta to form, a terrain must be close to the mouth of an ocean or a larger body of water.
  • The entering stream must be large enough and have large amount of sediment.
  • The river mouth must have been cut to the same level with that of the drainage basin.
  • Most rivers such terrain should be at their lower course where they flow with very low velocity.
  • Wave action should be minimal along such coasts.

These processes takes several thousands of years if not millions.

What is the role of oceans in the carbon cycle?
elixir [45]

Answer:The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean's surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths.
