How does nitrogen in the air and the soil converted into nitrates?
Nitrogen gas in the air is converted into nitrates through a process called nitrogen fixation by specialized bacteria. In the soil, nitrates are produced through nitrification, a two-step process involving the conversion of ammonium to nitrites and then to nitrates by bacteria.
How is nitrogen in the air converted into nitrates?
Nitrogen in the air is converted into nitrates through a process called nitrogen fixation, where certain types of bacteria or lightning convert atmospheric nitrogen gas (N2) into ammonia (NH3) or nitrate (NO3-). These nitrates can then be taken up by plants and incorporated into their tissues.
Does an electrical storm create nitrates?
Yes, electrical storms can create nitrates by converting nitrogen and oxygen molecules in the air into nitric oxide. This nitric oxide can then react with other molecules in the atmosphere to form nitrates.
Why is having too many nitrates and nitrates in the soil is so bad?
Nitrates are a fertilizer, so when nitrates hit a pond or stream, the plants there could overtake and drain all the oxygen out of all the plants, so the plants will die. The animals living there are also affected, because for example, fish in the water could die if a water hyacinth gets nitrates because the fish in the water will not get any sunlight.
Outline the major steps in the nitrogen cycle?
Nitrogen fixation: Bacteria convert atmospheric nitrogen into ammonia. Nitrification: Ammonia is converted into nitrites and then nitrates by nitrifying bacteria. Assimilation: Plants and other organisms take up nitrates to build proteins and nucleic acids. Ammonification: Decomposers break down organic matter releasing ammonia back into the soil. Denitrification: Denitrifying bacteria convert nitrates back into atmospheric nitrogen, completing the cycle.
Where is air pressure the highest sea level or atop a mountain?
Sea level

Which air route has the highest level of international passenger traffic in the world?
London-Paris
How does a spirit level indicate level?
A bubble of air is in a small slightly curved tube of alcohol. The bubble will float at the highest point and indicate level or not level.
Which altitudes would have the lowest air pressure and why?
The highest altitudes have the lowest air pressure. Air pressure increases as altitude decreases. Above sea level is lower pressure; below sea level is higher pressure.
How are Nitrates and Nitrogen different?
Nitrates are the negative ions (NO3-) of nitrate salts in solution and Nitrogen is a diatomic elemental gas (N2), 79% in fresh air, insoluble in water.
Where on earth is the air pressure the highest?
The air pressure is highest in areas which are the coolestÊwhich leads to air sinkingÊand creating high pressure at the surface. The opposite is true for areas which are warmest. This causes the air to rise, making pressure at the surface lower.
What part of Virginia would have the highest air pressure?
Typically the areas with the lowest elevation- which is sea level along the coast.

Where is the highest air pressure?
air pressure is the highest near the earths surface
3 Describe two ways in which nitrates can be replaced naturally in the soil?
1. lightning makes nitrates from nitrogen and oxygen in the air. the nitrates then get washed into the soil by rain. 2. animal and plants decompose- depositing organic nitrogen into the soil
What is The air mass with the highest actual water vapor content is?
The air mass with the highest actual water vapor content is the maritime tropical air mass, which originates over warm ocean waters. This air mass contains a significant amount of water vapor due to the high level of evaporation from the ocean surface.
