Educational worksheet identifying the four main types of clouds with visual examples and multiple-choice questions.

Let’s go step by step to solve this worksheet.

---

Part A: Identify and write the name of the clouds

We need to match each cloud drawing with its correct name from the four main types: Cirrus, Stratus, Cumulus, and Nimbus (or sometimes just “Cumulonimbus” for big storm clouds — but here we’ll stick to basic types).

Looking at the drawings:

1. The first cloud is thin, wispy, and looks like feathers or hair high in the sky → That’s Cirrus.
2. The second cloud is flat, layered, and stretches across the sky like a blanket → That’s Stratus.
3. The third cloud is puffy, white, and looks like cotton balls → That’s Cumulus.
4. The fourth cloud is dark gray, tall, and looks like it might bring rain → This is likely Nimbus (or Cumulonimbus), but since the worksheet says “four main types,” and often they teach Cirrus, Stratus, Cumulus, and Nimbus — we’ll call this one Nimbus.

Wait — let’s double-check standard elementary science:
The four main types are usually:
- Cirrus (high, wispy)
- Stratus (low, flat layers)
- Cumulus (puffy, fair weather)
- Nimbus (rain clouds — often combined as Cumulonimbus)

But in many school worksheets, especially at this level, they may use:
→ Cirrus, Stratus, Cumulus, and then either “Nimbus” or sometimes “Altostratus/Altocumulus” — but looking at Part B, question 4 mentions “blanket-like uniform grey or white” which is Stratus.

Actually, re-examining image #4 — it’s a large, dark, towering cloud — that’s typically called Cumulonimbus, but if we’re sticking to four simple names, maybe they expect “Nimbus”.

However, looking at common curriculum for grades 3–5, the four main types taught are often:
1. Cirrus
2. Stratus
3. Cumulus
4. Nimbus

So we’ll go with that.

Thus:

1. Cirrus
2. Stratus
3. Cumulus
4. Nimbus

BUT — wait! In some systems, “Nimbus” isn’t listed separately; instead, they say “Cumulonimbus” under Cumulus. But since the worksheet has 4 blanks and 4 images, and image 4 is clearly a rain cloud, “Nimbus” fits.

Alternatively, maybe they want “Cumulonimbus”? Let’s check Part B questions — they mention “Cirrus”, “Altostratus”, “Altocumulus”, “Stratus”, “Cumulus”. So perhaps they’re using more specific terms?

Wait — actually, in many modern curricula, the four main *categories* are based on height and shape:

High-level: Cirrus
Mid-level: Altostratus, Altocumulus
Low-level: Stratus, Stratocumulus, Nimbostratus
Vertical development: Cumulus, Cumulonimbus

But the worksheet says “Four Main Types” — so probably simplified to:

- Cirrus (wispy)
- Stratus (layered)
- Cumulus (puffy)
- Nimbus (rainy)

Yes — that’s standard for young students.

So final for Part A:

1. Cirrus
2. Stratus
3. Cumulus
4. Nimbus

Part B: Tick the correct answer

Question 1: How many main types of clouds are there?
Options: i. 3, ii. 4, iii. 2
Answer: The title says “Four Main Types”, and we just identified 4 → ii. 4

Question 2: Which one is a high-level cloud?
Options: i. Cirrus, ii. Altostratus, iii. Altocumulus
Cirrus clouds are always high up — above 20,000 feet. Altostratus and Altocumulus are mid-level.
So correct answer: i. Cirrus

Question 3: Which one is a low-level cloud?
Options: i. Altostratus, ii. Cirrus, iii. Cumulus
Cumulus clouds form low in the sky (usually below 6,500 ft). Cirrus is high, Altostratus is mid.
So correct answer: iii. Cumulus

Wait — actually, Cumulus can grow vertically, but their base is low. Yes, they are considered low-level clouds.

Question 4: These are low-level clouds that are blanket-like with a uniform grey or white color.
Options: i. Stratus, ii. Cirrus, iii. Altocumulus
Stratus clouds are exactly that — flat, layered, blanket-like, often gray or white, covering the whole sky.
Cirrus is wispy and high. Altocumulus is mid-level and patchy.
So correct answer: i. Stratus

Now let’s compile all answers.

Final Answer:

Part A:
1. Cirrus
2. Stratus
3. Cumulus
4. Nimbus

Part B:
1. ii. 4
2. i. Cirrus
3. iii. Cumulus
4. i. Stratus
