Water is all around us, and its importance to nearly every natural process on earth cannot be underestimated. The water cycle is the movement of water around the Earth in all its forms, from the ocean to the atmosphere, to snow, soil, aquifers, lakes, and streams on land, and ultimately backs to the ocean. This video explains what the water cycle is and how important it is to life on earth.

I hatch! Crawl! And swim!

Oh how I love my sweet life,

But—why’s the sea so warm?

Hi, apologies for the random comment, but we have just started an ambitious new community website based around our planet, and wanted to let people know who might be interested. It's at earth-forums (dot) com. We hope you like it :)

where's larry david

Do they replant the same specie or one that is a better faster harvest.

There really is no gray, you may easily consume spin or propaganda, but ecosystems indigenous to their region is what is best both for agriculture and environment (water included).

Where I live, they cut the trees down and then plant more trees, just like planting a field of wheat.

The lines are getting gray.

[Atoyota]

I feel you understand the difference.

Now had you mentioned clear-cutting forest for that purpose, I'd agree with you

[gregrutz]

''undermining nature for purely selfish reasons''

Like when we plow the plains and plant wheat, selfish?

[Atoyota]

agreed although coal ash is what affects polar ice as much as additional atmospheric energy (or more).

But seeding is undermining nature for purely selfish reasons, which to me is highly evil.

[gregrutz]

The Chinese building a coal fired power plant every 2 weeks might not help either.

Thank you for Earth Science week NASA, as an Earth Sciences Major I really enjoyed all the videos, very easy to understand and great base knowledge for any laymen.

So great footage as well.
