convection, conduction, and radiation
Human activities can have significant negative impacts on the atmosphere, such as air pollution and greenhouse gas emissions that contribute to climate change. While humans have the ability to degrade the quality of the atmosphere, it is unlikely that we can completely destroy it. However, it is essential to take action to mitigate harmful effects to ensure a sustainable future.
Convection: Warm air rises and cool air sinks, creating vertical movement of energy. Conduction: Energy is transferred through direct contact between the atmosphere and Earth's surface. Radiation: Solar energy is absorbed by the atmosphere and re-emitted as infrared radiation.
One way to preserve the atmosphere is to reduce greenhouse gas emissions by using renewable energy sources like solar and wind power. Planting trees and preserving forests can also help absorb carbon dioxide and improve air quality. Additionally, reducing air pollution from sources like vehicles and industries can protect the atmosphere.
Water enters the atmosphere through evaporation, where liquid water changes into water vapor due to heat energy. It also enters through transpiration, where water vapor is released into the air by plants through their leaves.
Water vapor enters the atmosphere through evaporation, where liquid water on the Earth's surface changes into a gas, and through transpiration, where water vapor is released from plants through their leaves.
Nitrogen enters the soil through the application of nitrogen-rich fertilizers and through the decomposition of organic matter, such as plant residues and animal manure. Nitrogen-fixing bacteria in legume plant roots also play a role in transferring nitrogen from the atmosphere to the soil.
Water leaves Earth's surface and enters the atmosphere through processes such as evaporation from oceans, lakes, and rivers, as well as transpiration from plants. Additionally, water is released into the atmosphere through sublimation from snow and ice.
Nitrogen can be removed from the atmosphere through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into forms that plants can use. Nitrogen can also be removed through lightning strikes, which can combine nitrogen molecules with oxygen to form nitrogen oxides that are washed out of the atmosphere by rain.
when nitrogen go from soil to back in atmosphere due to nitrogen fixing bacteria then it again return to soil due to lightning, dead animals, roots of plants and by other ways. and again go to atmosphere in this way nitrogen cycled.
Oxygen enters seawater through diffusion from the atmosphere at the water's surface and through photosynthesis carried out by marine plants and phytoplankton.
The majority of nitrogen which enters the body does so in the form of protein, which is composed of amino acids. Once the protein is broken down into these subunits, it enters the bloodstream where the cells of the body can absorb it and use it in many different ways. Excess amino acids (and thus excess nitrogen), along with cellular wastes containing nitrogen, are eventually filtered out of the blood by the kidneys and excreted in the urine in the form of urea, a waste product.
N2 gas is not actively removed from the atmosphere. It is the most abundant gas in the atmosphere and plays a crucial role in the nitrogen cycle. However, certain bacteria can convert N2 gas into a form that can be used by plants (nitrogen fixation).
Nitrogen can be fixed through biological nitrogen fixation by nitrogen-fixing bacteria, through industrial processes like the Haber-Bosch process, and through lightning in the atmosphere which converts nitrogen gas into nitrogen compounds that can be used by plants.
Nitrogen fixation is the process by which nitrogen gas in the atmosphere is converted into nitrogen compounds that plants can use. This can occur through biological nitrogen fixation, where certain bacteria convert nitrogen gas into ammonia, and through abiotic processes like lightning strikes, which convert nitrogen gas into nitrogen oxides that can be absorbed by rain and deposited in the soil.
Nitrogen can be removed from the atmosphere through biological processes such as nitrogen fixation by plants and bacteria, where nitrogen gas is converted into a form that can be used by living organisms. It can also be removed through industrial processes like the Haber-Bosch process, which converts nitrogen gas into ammonia for use in fertilizers and other products.
