Scientists estimate that it can take a single water molecule as long as 4000 years to complete one cycle.
45 days
The cycle of the moon's phases runs 29.53 days.
Water will exist on earth forever because the water cycle gives a continuous supply of water.
a drop of water may spend over 3,000 years in the ocean before moving on to another part of the water cycle
There are many routes through the water cycle. If a drop of water falls on a hot tin roof it evaporates almost immediately and is set to start all over again. Other drops may soak into the ground and evaporate or be taken up by plants to transpire into the air over the course of days or weeks. Still other drops may flow into rives or lakes or oceans where the time to evaporation is years to hundreds of years. Water falling as snow onto glaciers and the antarctic may be tied up as ice for thousands of years, water seeping into deep underground reservoirs may be there as long as 10,000 years.
Not possible to tell.
It takes too long for a complete water cycle process. It is however a continuous process.
it takes 1 day
A Betta does not have a "nitrogen cycle"
hey what are you doig
One complete cycle every 28 days.
Water cycle is a continuous process. It will last long.
28 days
5 years
A cycle in a sound wave is the time taken for one complete vibration.
The gymnosperm life cycle usually takes two years to complete. The cycle begins as male cones release their pollen grains.
29.53 days
