oxygen cycle
The oxygen cycle is an example of the _______ cycle.
Carbon is found on Earth in the form of three different allotropes including
amorphous, graphite, and diamond
Explain the role of microorganisms in Earth's nitrogen cycle.
convert nitrogen gas in the atmosphere to ammonia.
In the oxygen cycle, the movement of oxygen takes place within
In the oxygen cycle, the movement of oxygen takes place within the atmosphere, biosphere and lithosphere.
Describe and illustrate Earth's carbon cycle, including how energy from the sun drives Earth's carbon cycle.
chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules
Explain the significance of the nitrogen cycle to life on Earth.
The nitrogen cycle matters because nitrogen is an essential nutrient for sustaining life on Earth.
Oxygen from the atmosphere is used up in combustion, respiration and the form of oxides of nitrogen.
Ozone and oxygen
Describe the different forms taken by carbon and the reservoirs where they are found.
the atmosphere, the oceans, land, and fossil fuels.
The processes in which atmospheric oxygen is used are mentioned below.
combustion, respiration and the form of oxides of nitrogen.
Oxygen from the atmosphere is used up in processes, namely
Oxygen from the atmosphere is used up in combustion, respiration and the form of oxides of nitrogen.
Give examples of carbon forms found on Earth.
Carbon is found on Earth in the form of three different allotropes including amorphous, graphite, and diamond.
The primary reservoirs of oxygen are mentioned below.
The oxygen cycle is a biogeochemical cycle that describes the movement of oxygen within the earth's three main reservoirs which are the atmosphere (air), the hydrosphere (water), and the lithosphere (land).
The atmosphere contains ________ of oxygen.
21%
Describe and illustrate Earth's nitrogen cycle.
A plant takes nitrogen from the soil by absorbing it through its roots.
How has the Haber-Bosch process impacted the global nitrogen cycle?
For example, the Haber Process uses tonnes of energy, consuming around 1-2% of the world energy's supply. It also contributes to a build-up of reactive nitrogen in the biosphere, causing potential harm to the nitrogen cycle.
