Dear;
Can Someone Please Tell Me What is The Total Amount Of Water On Earth And Its Proportion To The Dry Land Or Space.
Thanks.

From what I know there are 326 million trillion gallons.
And 25% of land? Im not for sure about the land but I hope I helped. Your best bet is Google is good if no one knows this answer :)

70% water 30% land

Here are some statistics for you : Area of Earth's Land Surface (http://hypertextbook.com/facts/2001/DanielChen.shtml)

Hope it helps :)

29% of Land & 71% of water
