In evaporation the element or the compound in it's liquid state changes to gaseous state below the temperature at which the it boils. This is due to the high temperature. Due to high temperature the water from different water bodies enters the atmosphere in the form of vapours. In the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. Transpiration is a process by which the moisture is transferred from roots to the outside of the leaf whic
Therefore, In water cycle, water from rivers, lakes and streams enters the atmosphere through vaporisation. in the carbon cycle, water exits the pore of leaves in plants by a process called as transpiration. In nitrogen cycle, the water as well as dead organism moves nitrogen from the atmosphere into the soil.
