To an extent this is true....everything in earth goes through a process called the hydological cycle.This process clearly shows that due to the processes of precipation,condensation,infiltration,runnoff as well as evaporation.The process begins with condensation, when water vapor condenses in the atmosphere to form clouds. Condensation occurs when the temperature of the air or earth changes. Water changes states when temperatures fluctuate. So when the air cools enough, water vapor has to condense on particles in the air to form clouds. This process is very noticeable on plants as they dew in the morning.
As clouds form, winds move them across the globe, spreading out the water vapor. When eventually the clouds can't hold the moisture, they release it in the form of precipitation, which can be snow, rain, hail, etc.
The next three stages: infiltration, runoff, and evaporation occur simultaneously. Infiltration occurs when precipitation seeps into the ground. This depends a lot on the permeability of the ground.
Permeability is the measure of how easily something flows through a substance.The more permeable, the more precipitation seeps into the ground. If precipitation occurs faster than it can infiltrate the ground, it becomes runoff. Runoff remains on the surface and flows into streams, rivers, and eventually large bodies such as lakes or the ocean. Infiltrated groundwater moves similarily as it recharges rivers and heads towards large bodies of water.
As both of these processes are happening, the power of the sun is driving this cycle by causing evaporation. Evaporation is the change of liquid water to a vapor. Sunlight aids this process as it raises the temperature of liquid water in oceans and lakes. As the liquid heats, molecule are released and change into a gas. Warm air rises up into the atmosphere and becomes the vapor involved in condensation.
Considering so little of the water on earth is drinkable to people, it is amazing the supply has survived as long as it has. The hydrologic cycle continues to move water and keep sources fresh. It is estimated that 100 million billion gallons a year are cycled through this process. Without this process life on Earth would be impossible. We need it to sustain us and for all of our life processes to function. Without water, life would not be possible on Earth.
Therefore,all the water in the earth eventually goes through a cycle,thus it is true.

Nope. Just like not all rivers lead to the ocean. Some rivers lead to lakes, some simply disappear (go underground, evaporate).
The same thing happen with sewage (or any type of used water). When there's no collection system, it simply goes underground and contributes to ground water, and if there's a sewage collection system and treatment, the treated water can be inserted into aquifers (underground), used for irrigation, disposed into lakes, rivers, streams, OR, finally, the ocean! ;)

at the same time as 8 glasses is declared to be the norm, eating too lots water will harm you and possilby kill you. if you're strolling round with a bottle of water and keep eating it forcefully wondering "water is sturdy, why now no longer drink further and larger" then you definately may favor to likely disturb the ion stability on your body and reason intense themes. on the distinct hand dehydration is an probability, yet not likely contained in the shape you do now no longer drink that lots water. i'd like to say once you're a splash thirsy, drink some water. in case you drink a huge type of caffiene or alcohol then devour a splash more effective water. eating too lots water can kill you, now no longer eating adequate received't kill you. 8 glasses of water varies with the help of skill of sooooo many criterias. Are you 3 hundred lbs or 100 lbs, do you run contained contained in the blaring image voltaic?

If we are talking about rivers and streams, yes eventually they do. Most lakes have an outlet also.
As far as sewage, if you live in a city, sewage goes to the sewage/water treatment plant and the effluent is released into the river or sea. If you live out in the country where septic tanks are used, they are emptied by a truck which goes to a water treatment plant.
Some ponds evaporate to rain elsewhere. Some rivers do go under ground for a time. Some places do not treat sewage and then it gets into water supplies. Water in wells got there by filtering down from the surface or from an underground river.

Not true. There are lots of places on earth not directly linked to a natural water source. Some water is simply sent through treatment plants in a community and eventually distributed back to residential neighborhoods for use once again.

the life's work of a drop is to get to the ocean. If left to its own devices it will. However, it may take a few detours along the way. Not all drops are destine to full fill their life's ambition; some are subject to evaporation.

Yes it is sadly true. Greenpeace has been tiring to help nations of the world to understand that it is very wrong to do so, but no one is listening,no one.

Nope, some evaporates, some go into ground water and some just go downstream.
