It looks like you've uploaded a worksheet titled "Volcano Alphabet Activity" where the task is to put a list of volcano-related words in alphabetical order.

Here's how we can solve this step by step:

🔍 Step 1: Identify the Words

The words provided at the bottom of the page are:

- Cascadia
- crater
- erupt
- fissure
- Kilauea
- lava
- magma
- Mount St. Helens
- volcano
- cone
- active
- St. Helena
- Plinian
- shield

> Note: "St. Helena" might be a typo or confusion — it’s likely meant to be "St. Helens", as Mount St. Helens is a famous volcano. But since it's listed as "St. Helena", we'll include it as-is for now.

Let’s list them clearly:
1. Cascadia
2. crater
3. erupt
4. fissure
5. Kilauea
6. lava
7. magma
8. Mount St. Helens
9. volcano
10. cone
11. active
12. St. Helena
13. Plinian
14. shield

🔤 Step 2: Sort in Alphabetical Order

We’ll sort these words alphabetically, ignoring case (but keeping original capitalization for proper nouns).

Let’s go through each word and compare letter by letter.

#### Start with first letters:
- A: active
- C: Cascadia, cone, crater
- E: erupt
- F: fissure
- K: Kilauea
- L: lava
- M: Mount St. Helens
- P: Plinian
- S: St. Helena, shield
- V: volcano

Now let’s sort within each group.

#### A
- active

#### C
- Cascadia
- cone
- crater

(“Cascadia” comes before “cone” because 'a' < 'o'; “cone” before “crater” because 'o' < 'r')

So: Cascadia, cone, crater

#### E
- erupt

#### F
- fissure

#### K
- Kilauea

#### L
- lava

#### M
- Mount St. Helens

#### P
- Plinian

#### S
- St. Helena
- shield

Now compare: “St. Helena” vs “shield”

- “St.” starts with S, then T → but “shield” starts with S, then H.
- Since H comes before T, shield comes before St. Helena

So: shield, St. Helena

#### V
- volcano

✔ Final Alphabetical Order:

1. active
2. Cascadia
3. cone
4. crater
5. erupt
6. fissure
7. Kilauea
8. lava
9. magma
10. Mount St. Helens
11. Plinian
12. shield
13. St. Helena
14. volcano

Wait! We missed magma earlier. Let's double-check the original list.

Original list includes:
- magma
- Plinian
- shield
- St. Helena
- etc.

Yes, magma should be included.

Let’s recheck all 14 words:

1. active
2. Cascadia
3. cone
4. crater
5. erupt
6. fissure
7. Kilauea
8. lava
9. magma
10. Mount St. Helens
11. Plinian
12. shield
13. St. Helena
14. volcano

But wait — "Plinian" starts with P, so it should come after Mount St. Helens (M) and before shield (S).

And "magma" starts with M, so it should come before "Mount St. Helens".

So let's fix that.

Compare magma and Mount St. Helens:
- Both start with M
- Next letter: a vs o → a < o, so magma comes before Mount St. Helens

Also, Plinian (P) comes after Mount St. Helens (M), but before shield (S)

And St. Helena vs shield: s-h-i-e-l-d vs s-t... → h < t, so shield comes before St. Helena

Final corrected order:

1. active
2. Cascadia
3. cone
4. crater
5. erupt
6. fissure
7. Kilauea
8. lava
9. magma
10. Mount St. Helens
11. Plinian
12. shield
13. St. Helena
14. volcano

✔ Final Answer (to fill in the blanks):

1. active
2. Cascadia
3. cone
4. crater
5. erupt
6. fissure
7. Kilauea
8. lava
9. magma
10. Mount St. Helens
11. Plinian
12. shield
13. St. Helena
14. volcano

📝 Notes:

- The word "St. Helena" may be a mistake — it's not a known volcano. It's likely meant to be "St. Helens", which is part of Mount St. Helens. But since it's written as "St. Helena", we used it as given.
- If it was a typo and should be "St. Helens", then it would be combined with "Mount St. Helens" — but they’re separate entries here.
