Educational worksheet on natural landforms and physical features, designed for learning geography and map skills.

Let’s solve this step by step.

We have 10 natural features on the left:
- river
- bay
- island
- gulf
- mountain
- plain
- lake
- peninsula
- valley
- volcano
- ocean

And 11 definitions numbered 1 to 11. We need to match each feature with its correct definition number.

Let’s go one by one:

1. river → A long, narrow body of water that flows. That matches #8: “long, narrow body of water”

2. bay → A large area of sea or ocean partially enclosed by land. That’s #11.

3. island → Land surrounded completely by water. That’s #2.

4. gulf → Inlet of a large water body that extends into the land; smaller than a gulf? Wait — actually, definition #4 says: “inlet of a large water body that extends into the land; smaller than a gulf” — that doesn’t make sense for “gulf”. Let me re-read.

Wait — definition #4 says: “inlet of a large water body that extends into the land; smaller than a gulf” — that must be describing a *bay*, not a gulf. But we already matched bay to #11.

Hold on — let’s check again.

Actually, looking at standard geography:

- Gulf = larger inlet (like Gulf of Mexico)
- Bay = smaller inlet (like San Francisco Bay)

But in the list:

Definition #4: “inlet of a large water body that extends into the land; smaller than a gulf” → This is describing a bay

Definition #11: “large area of a sea or ocean partially enclosed by land” → This could also describe a bay or gulf.

Hmm — maybe there’s a mix-up. Let’s look at all definitions carefully.

Let me list them clearly:

Definitions:

1. land rising high above the land around it → mountain

2. land surrounded completely by water → island

3. piece of land surrounded by water on all but one side → peninsula

4. inlet of a large water body that extends into the land; smaller than a gulf → bay

5. Earth opening that spills lava, rock, and gases → volcano

6. large inland body of water → lake

7. lowland between hills or mountains → valley

8. long, narrow body of water → river

9. large area of flat grasslands → plain

10. vast body of salt water → ocean

11. large area of a sea or ocean partially enclosed by land → gulf

Ah! So:

- Gulf is #11 (larger enclosed area)
- Bay is #4 (smaller inlet)

That makes sense now.

So let’s redo the matching correctly:

Feature → Definition Number

- river → #8 (long, narrow body of water)

- bay → #4 (inlet... smaller than a gulf)

- island → #2 (surrounded completely by water)

- gulf → #11 (large area... partially enclosed by land)

- mountain → #1 (land rising high...)

- plain → #9 (flat grasslands)

- lake → #6 (large inland body of water)

- peninsula → #3 (surrounded on all but one side)

- valley → #7 (lowland between hills/mountains)

- volcano → #5 (spills lava...)

- ocean → #10 (vast body of salt water)

Perfect — all 11 are used, and each feature has a unique match.

Now, the second part says: “Now write each feature’s number on the map.” But since we don’t have the actual map image with labeled boxes, and the user didn’t ask us to fill in the map (and we can’t see which box corresponds to which feature), we’ll just provide the matching as requested in the first part.

The main task was to match each formation with its definition by writing a number in each blank — so we’ve done that.

Final Answer:

river — 8
bay — 4
island — 2
gulf — 11
mountain — 1
plain — 9
lake — 6
peninsula — 3
valley — 7
volcano — 5
ocean — 10
