What is the difference between evaporation and transpiration in the water cycle?
Evaporation can be defined as the process where liquid water is transformed into a gaseous state. Transpiration is the process of water loss from plants through stomata. Stomata are small openings found on the underside of leaves that are connected to vascular plant tissues.
Evaporation is when water vapor comes from liquid surface water, such as streams, lakes, rivers, and oceans. Transpiration is when water vapor comes from liquid water excreted by plants. Plants ‘breathe’ by exchanging carbon dioxide for oxygen through small openings in their leaves called stomata during photosynthesis.
How is transpiration related to the evaporation process?
Transpiration is just a subset of the evaporation process, and it’s the water that is inside plants, and then when that evaporates and moves into the atmosphere, that process is called transpiration. And it’s very much part of the living processes of the plant. It’s all occurring within a cycle – and I guess when it comes to plants,…
When does the process of evaporation take place?
The natural process of transforming water from its liquid state to the gaseous state is mainly referred to as evaporation. This natural phenomenon generally takes place only when water is available- it can be from any water bodies including oceans, rivers, lakes, ponds, or even from the soil.
How long does it take for a molecule of water to evaporate?
Once evaporated, a water molecule spends about 10 days in the air. The process of evaporation is so great that without precipitation runoff, and groundwater discharge from aquifers, oceans would become nearly empty. Your table salt might have come from an evaporation pond.
How much energy is needed for the evaporation of one gram of water?
Altogether, the total amount of energy required for the evaporation of one gram of water is about 600 calories of heat energy. Transpiration is a biological process in which the water molecules are lost in the form of water vapours from the aerial parts of the plants.
