What is the volume of Earth's atmosphere?
The "effective volume" of the Earth's atmosphere is about 4.2 billion cubic kilometers. This figure is the surface area of the Earth (509 million square kilometers) times the "effective thickness" of the atmosphere (8.2 kilometers, or about 27,000 ft). The effective thickness and volume are what the thickness and volume of the atmosphere would be if the entire atmosphere were at sea level conditions. The actual volume of the atmosphere is considerably greater than its effective volume, as its pressure and density drop with increasing altitude. If we adopt the "Karman Limit" of 100 km elevation as the boundary between earth and space, the volume of the atmosphere would be 100 times 509 million or about 51 billion cubic kilometers. However, the Karman Limit is a non-physical and rather arbitrary boundary.
What information can scientists obtain from meteors?
Information has ovation.
How many grams of IKI would it take to obtain a 100mL solution of 0.300 M IKI?
It would be 12.6g of IKI to obtain the 100mL solution of 0.300 M IKI.
How would people on the moon obtain and conserve water?
In their cups.
What was the mission of the spacecraft viking 1?
The mission of the spacecraft Viking 1 was to orbit and land on Mars to search for evidence of past or present life. It successfully landed on Mars in 1976 and conducted experiments to analyze the Martian soil and atmosphere for signs of life.
If nitrogen in the atmosphere is not in a form plants can use how do they get nitrogen what is this process called?
Plants obtain nitrogen through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can use, such as ammonia. This can occur naturally in soil or through symbiotic relationships with certain plants like legumes.
Do animals take in nitrogen directly from the atmosphere?
No, animals do not take in nitrogen directly from the atmosphere. They obtain nitrogen through consuming plants or other animals that have already processed nitrogen into organic compounds. Nitrogen fixation by certain bacteria in the soil or symbiotic organisms in plants helps convert atmospheric nitrogen into forms that can be used by animals.
Where do bacteria in the soil obtain their nitrogen?
Bacteria in soil obtain their nitrogen primarily from organic matter, such as dead plants and animals. They can also obtain nitrogen through nitrogen fixation, a process where certain bacteria convert atmospheric nitrogen into a form that plants can use.
How does nitrogen get from organisms back into the atmosphere?
Nitrogen is returned to the atmosphere through the process of denitrification, where bacteria convert nitrates in the soil back into nitrogen gas. This process completes the nitrogen cycle as nitrogen is released back into the atmosphere as a gas.
Describe the path of nitrogen from the atmosphere to plant proteins?
Nitrogen gas in the atmosphere is converted by nitrogen-fixing bacteria into a form that plants can absorb, such as ammonium or nitrate. Plants take up these nitrogen compounds from the soil through their roots and incorporate them into proteins. When animals eat plants, they obtain nitrogen from plant proteins, continuing the cycle.
How do animals obtain their nitrogen requirements?
Animals obtain their nitrogen requirements primarily by consuming nitrogen-rich foods such as plant proteins or other animal tissues. The proteins in these foods are broken down into amino acids, the building blocks of proteins, which are then used by the animal to meet its nitrogen needs. Nitrogen can also be obtained indirectly by consuming microbes that can convert atmospheric nitrogen into forms that animals can use.
How do plants and animals get nitrogen if not from the atmosphere?
Plants get nitrogen from the soil through their roots, either in the form of nitrates or ammonium. Animals obtain nitrogen by consuming plants or other animals that have already incorporated nitrogen into their tissues. In this way, nitrogen is cycled between plants and animals in ecosystems.
How do animal obtain nitrogen?
Animals obtain nitrogen by eating plants which have absorbed nitrogen from the soil.
When there is not enough nitrogen in the atmosphere for plants how do the plants get it?
Plants can obtain nitrogen from the soil through their roots. They form symbiotic relationships with nitrogen-fixing bacteria in the soil, which convert atmospheric nitrogen into a form that plants can use. Additionally, decaying organic matter in the soil releases nitrogen that plants can absorb.
What can be heated to obtain nitrogen?
Either ammonium nitrite or ammonium dichromate can he heated to obtain nitrogen gas.
Which organisms convert nitrogen into a form that is usable by humans?
Nitrogen-fixing bacteria in the soil, such as Rhizobium and Azotobacter, convert atmospheric nitrogen into a form that plants can absorb. By consuming these nitrogen-fixing plants (e.g., legumes like peas and beans), humans can obtain the nitrogen they need for growth and development.
How do consumers obtain nitrogen?
Consumers obtain nitrogen through the food they eat, as nitrogen is an essential component of proteins. Inorganic nitrogen can also be found in the air we breathe, but our bodies cannot use this form directly.
