1:GROUND WATER
Do you know much of our fresh water comes from underground?
And this is where many mysterious springs(1) may be found.
You see,some parts of the ground are permeable and some not,
Because of the impermeable parts,much fresh water have we got.
Permeable means water can go through it and impermeable means it cannot.
The impermeable ground layer will stop the water,collecting it like a pot.
We can sink a well because of underground water,
Life钬檚 liquid we have when other sources falter.
Where does this fresh water come from?
Well,for starters,you may thank the sun.
That钬檚 right!The sun evaporates water from oceans and lakes and clouds form.
The fresh water is then dropped back down to earth allowing new life to be born.
But also realize not all water is used by us or evaporates,
Or runs back to the nearest ocean or nearby lake.
But over millions of years,in the ground does much of it soak,
Which is mighty good news for us and other kindly folk.
Because often we can find fresh water far away from a stream,
And when we do,the wonder of it can often make us beam.
Simply from the permeability or impermeability of sediment and rock,
We find the liquid of life,this secret we do unlock.
2:WATER CYCLE
The amount of water on earth always remains the same,
And water will often gravitate from whence it originally came.
It all starts with evaporation from our oceans and lakes,
And this process,does for us,much fresh water make.
Fortunately,salt is a solid and does not evaporate.
It is this important fact that very much rests our fate.
For animals,plants and humans can钬檛 drink water with salt.
If we did,it would soon bring life to a screeching halt.
Now as this water evaporates,it vaporizes into clouds,
Which at times produces thunder,known to be quite loud.
These clouds have tons of water,yet they float in the air,
Releasing their water over oceans and land,seemingly without a care.
The water is in tiny droplet form and the cloud is very very large,
So the average d
