What's the difference between groundwater, and water in soil?

24

Water in soil = water in the pores of the soil

Groundwater = water below the water table

28

I am guessing that water in soil is the water contained in the upper layers of soil and dirt while groundwater is used for water reserves far under the ground much below the soil layers and even below the rock layers

It's terrible. It's missing an explanation for what the outflow part from "groundwater" is.

It isn't showing an outflow from the groundwater slice, each circle is an expanded view of the small slice in the circle above. The only thing missing is the percentage of the small slice in the circle where it begins. The soil, atmosphere, and organism water are not falling under groundwater, they are just much smaller slices of the freshwater circle.

If you want to make it much easier to read, separate saltwater and freshwater, and change the bottom charts percentages from 52% and 38% to 0.52% and 0.38%.

That doesn't make sense. Water in living organisms, water vapour in the air and in the soil are not surface water.

This chart is truly terrible throughout.

I don't find it difficult to read. Most of the freshwater consists of groundwater and ice; the rest is made up of what's shown in the circle at the bottom.

I'll give you that. No more wheels, but value labels for those would have been good.

So organisms have just as much water as rivers? That seems surprising, but I guess it could be that way.

Thinking the same thing. But now that I think about it, there is a lot of vegetation that would take up the majority of that share. Think about all the streama and rivers, then think about all the vegetation that surrounds and how easy it would be to fill those rivers with it. But still that's a lot of water.

50% of a tree is apparently water, which seems like a lot.

Could just be that whatever was used to create the diagram has a minimum slice size and anything below that just gets rounded up. Without labels for the size of each slice it's impossible to tell.

Would be nice if they included a source for this data. Then it would not be impossible to tell.

Just eyeballing it the organisms looks maybe 2/3rds the size of rivers?

I wonder how the amount of ground water has changed over the last ~100 years. Has pumped ground water raised the oceans a measurable amount?

Climate change looks more frightening now.

Yep, melting ice will cause sea level rise, and millions live in the coastal cities that will be affected.

Thanks to this graphic, I have a hard time understanding how ~2% more water from glaciers will flood the planet

Living next to the great lakes, it never really hit me how unbelievably privileged I am to be able to swim in large bodies of freshwater until a few years ago. This chart definitely reinforces that.
