Water on Earth - Worksheet | Distance Learning - Free Printable

Let me carefully examine the diagram to match each label with the correct part of the water distribution.

First, I'll identify the main sections:
- The top large circle shows "97%" freshwater? Wait—that can't be right. Actually, looking more closely, the top circle is labeled "FRESHWATER" but shows 97%—that seems incorrect because we know oceans are ~97% of Earth’s water and are *saltwater*, not freshwater.

Wait—I need to re-read: The arrow says “WATER SUPPLY SUMMED UP”, and the top circle is likely the *total* water on Earth. Standard knowledge: ~97% is ocean (saltwater), ~3% is freshwater.

So the top circle (97%) must be Oceans — even though it's labeled "FRESHWATER" in the diagram? No—actually, looking again: the label "FRESHWATER" is pointing *downward* from the 97% circle, but that’s probably a layout issue. Let me trace the arrows:

- Top circle: 97% → points down to a pie chart labeled "FRESHWATER" (but that can’t be; 97% is saltwater). Hmm.

Actually, the diagram structure is:
1. Top sphere: 97% — this is the largest portion → must be Oceans
2. Below it: a pie chart labeled “FRESHWATER” divided into:
- 70% (ice caps & glaciers)
- 29% (groundwater)
- 1% (easily accessible freshwater)
3. Then below that: another pie showing “EASILY ACCESSIBLE FRESHWATER” broken into:
- 52% (lakes)
- 38% (soil moisture)
- 1% (rivers)
- plus water vapor 8%, water in living things 1% — but those percentages don’t add to 100%; likely those are *of total freshwater* or separate.

Wait—the labels to assign are:
- Ice Caps and Glaciers
- Oceans
- Lakes
- Groundwater

And there are 4 blank boxes in the diagram.

Let me locate the blanks:
- One blank inside the top 97% circle → should be Oceans
- One blank pointing to the 70% slice of the freshwater pie → Ice Caps and Glaciers
- One blank pointing to the 29% slice → Groundwater
- One blank pointing to the 52% slice in the bottom pie → Lakes

Yes — that matches standard Earth water distribution:
- Oceans: ~97%
- Of remaining 3% freshwater:
- Ice caps & glaciers: ~68.7% of freshwater ≈ 70% of the 3% → so 2.1% of total → shown as 70% of freshwater pie
- Groundwater: ~30% of freshwater → 29% shown
- Lakes: ~0.26% of total water → about 52% of *easily accessible* freshwater (which is ~1% of total freshwater)

So the blanks correspond to:
1. Top 97% circle → Oceans
2. 70% slice (freshwater pie) → Ice Caps and Glaciers
3. 29% slice (freshwater pie) → Groundwater
4. 52% slice (easily accessible pie) → Lakes

Now I’ll zooming into each blank region to be sure.
