Answer:
i would like to choose sublimation process to explain about water cycle.As mentioned, sublimation is the process in which snow melts and water get vaporized. Ice melts and turns into water which flows to the seas and oceans.When the temperature increases during the day time, water gets vaporized.Water vapour begin to move upward.As we know, temperature decreases with the increase in height.Due to which water vapour rises,cools and then changes into tiny water molecules.Those water molecules forms cloud.Then the clouds get heavier and begin to collide with each other.As a result rain fall occurs.
Evapotranspiration has also the same process but the difference is that it involves vaporization of water from some biological factor like plants and physical factor like from soil .
i think its my first longest answer which i answered here.Thank you for the amaizing question. Its simple but most important topic
In the gradual speciation<span> model, species diverge slowly over time in small steps while in the punctuated equilibrium model, a new species diverges rapidly from the parent species. The two key influencing factors on the change in </span>speciation rate<span>are the environmental conditions and the population size.</span>
