What processes are part of the water cycle? What role does gravity play in the water cycle?

That is the existence and movement of water on the ground, in the earth and in the earth's atmosphere. Earth water is always in motion and transition from one state to another, from liquid to vapor to solid and vice versa. The water cycle has been going on for billions of years and all life on earth depends on it, the earth would be a place that could not be lived without water.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
