Worksheets on the structure of the Sun, featuring a diagram, crossword puzzle, and questions, ideal for science education.

Let’s solve the crossword puzzle about the Structure of the Sun.

We’ll go clue by clue, using what we know about the sun and matching it to the clues.

---

Across Clues:

6. “about 70% of the sun is made of this” → That’s Hydrogen. (The sun is mostly hydrogen.)

7. “the innermost layer of the sun where fusion occurs” → That’s the Core. (Fusion happens in the core.)

8. “an area found above the core; transports energy from the core to the outer layers of the sun” → That’s the Radiative Zone. (Energy moves through radiation here.)

10. “a tremendous explosion of energy on the sun” → That’s a Flare or Solar Flare. But looking at the grid, it fits “Flare” better if space allows — but let’s check length. Wait, clue says “explosion of energy” — could also be “Prominence”? No, prominence is loop-like. Actually, “flare” is short. Let’s hold that thought.

Wait — looking again: Clue 10 says “tremendous explosion of energy on the sun” — that’s definitely a Solar Flare, but maybe just “Flare”. However, in many worksheets, they use “Flare” for short. But let’s see the grid later.

Actually, let’s look at Down clues first — sometimes they help fill Across.

Down Clues:

1. “the visible surface of the sun” → That’s the Photosphere. (That’s the layer we see.)

2. “the lower region of the sun’s atmosphere” → That’s the Chromosphere. (It’s below the corona.)

3. “the outermost layer of the sun’s atmosphere” → That’s the Corona. (You see it during eclipses.)

4. “intense magnetic storms on the sun” → Those are Sunspots? Wait — no, sunspots are dark spots. Magnetic storms? Could be “Flares” again? Or “Prominences”? Hmm.

Wait — actually, “intense magnetic storms” might refer to Solar Storms, but that’s not standard. Maybe “Sunspots” are associated with magnetic fields. Let’s think differently.

Actually, clue 4: “intense magnetic storms on the sun” — often called Solar Flares or Coronal Mass Ejections, but those are long. Perhaps it’s “Spots”? Not quite.

Wait — let’s look at clue 5: “a large loop-like structure that extends from the surface of the sun” → That’s a Prominence. (Yes! Prominences are loops.)

Clue 6: “produced from fusion of hydrogen atoms” → That’s Energy. (Fusion makes energy.)

Clue 9: “a stream of charged particles released from the upper atmosphere of the sun” → That’s the Solar Wind.

Now back to Across:

Clue 10: “tremendous explosion of energy on the sun” → Now that we have “Prominence” for down 5, and “Flare” might fit elsewhere... Actually, “Flare” is common for explosions. Let’s assume Flare for now.

Clue 11: “energy moves from the core to the surface by radiation and ___” → The other way is Convection. (In the convection zone, heat moves by convection currents.)

Clue 12: “the sun emits light and heat and other forms of ___” → That’s Radiation. (Sun gives off electromagnetic radiation.)

Now let’s map these to the grid based on letter counts.

Looking at the crossword grid (even though we can’t see exact boxes, we can infer from typical layouts):

Assume:

- Across 6: Hydrogen → 8 letters → fits.
- Across 7: Core → 4 letters → fits small box.
- Across 8: Radiative Zone → too long? Wait, maybe just “Radiative”? But clue says “area found above the core” — that’s radiative zone. But perhaps in worksheet, they shorten? Or maybe it’s “Zone”? No.

Wait — perhaps the across answers are single words? Let me re-read clues.

Actually, looking at the word bank provided in the image (which we can’t describe, but you mentioned terms like Convection Zone, Radiative Zone, etc.), so likely the answers include multi-word terms.

But in crosswords, sometimes they combine or abbreviate.

Alternatively, let’s list all possible answers clearly:

From science knowledge:

Layers of the Sun (from inside out):

- Core
- Radiative Zone
- Convection Zone
- Photosphere
- Chromosphere
- Corona

Other features:

- Sunspots
- Solar Flares
- Prominences
- Solar Wind
- Hydrogen (main component)
- Energy (product of fusion)
- Radiation (how energy travels)

Now match to clues:

Across:

6. Hydrogen ✔
7. Core ✔
8. Radiative Zone → but how many letters? If grid has space, maybe “Radiative” alone? Unlikely. Perhaps the worksheet expects “RadiativeZone” as one word? Or maybe it’s “Zone” — no.

Wait — clue 8 says: “transports energy from the core to the outer layers” — that’s the function of the Radiative Zone, yes.

But let’s look at Down 11: “energy moves from the core to the surface by radiation and ___” → That must be Convection. So Across 11 is probably not needed — wait, Across 11 is: “energy moves from the core to the surface by radiation and ___” — oh! I misread.

Let me correct:

Across 11: “energy moves from the core to the surface by radiation and ___” → Answer: Convection

Across 12: “the sun emits light and heat and other forms of ___” → Radiation

Down 4: “intense magnetic storms on the sun” → This is tricky. Could be Flares, but flares are explosions. Magnetic storms might refer to Sunspots because they’re caused by magnetic activity. In many educational contexts, sunspots are linked to magnetic storms. Let’s tentatively say Sunspots.

Down 5: “large loop-like structure” → Prominence

Down 6: “produced from fusion of hydrogen atoms” → Energy

Down 9: “stream of charged particles” → SolarWind or just Wind? Usually “Solar Wind”, but may be shortened.

Now let’s assign based on common worksheet answers:

Finalizing:

Across:

6. Hydrogen
7. Core
8. RadiativeZone → but likely written as two words? In crossword, maybe combined. Since it's a school worksheet, perhaps they accept "Radiative" if space is limited, but better to use full term.

Wait — looking back at your initial description, there’s a word bank including: Sunspots, Core, Convection Zone, Radiative Zone, Photosphere, Chromosphere, Corona.

So likely the answers come from that list plus others.

Also, clue 10: “tremendous explosion” — that’s Flare, which isn't in the word bank, but might be accepted.

Perhaps for clue 4 Down: “intense magnetic storms” — could be Sunspots, since they are regions of strong magnetic fields.

Let me try to fill logically:

Assume the grid has:

Across 6: H Y D R O G E N (8 letters)
Across 7: C O R E (4 letters)
Across 8: R A D I A T I V E Z O N E — too long. Maybe it's "Radiative" only? But clue specifies the zone.

Another idea: perhaps "Zone" is part of it, but let's count letters in grid.

Since I don't have the actual grid, I'll rely on standard answers for such worksheets.

Common answers for this type of crossword:

Across:

6. Hydrogen
7. Core
8. Radiative
10. Flare
11. Convection
12. Radiation

Down:

1. Photosphere
2. Chromosphere
3. Corona
4. Sunspots
5. Prominence
6. Energy
9. SolarWind (or Wind)

But "SolarWind" is 9 letters, might not fit.

Perhaps Down 9 is "Wind" alone? But that's not accurate.

Another possibility: Down 9 is "Particles"? No.

Let's think of synonym: "stream of charged particles" = Plasma? But plasma is state, not stream.

Actually, it's Solar Wind, and in some puzzles, they write it as one word or abbreviate.

Given constraints, I'll go with most logical matches.

After careful consideration, here are the correct answers based on standard solar structure knowledge and typical worksheet expectations:

Across:
6. Hydrogen
7. Core
8. Radiative
10. Flare
11. Convection
12. Radiation

Down:
1. Photosphere
2. Chromosphere
3. Corona
4. Sunspots
5. Prominence
6. Energy
9. SolarWind (if space allows, else "Wind" — but "SolarWind" is more accurate)

However, to match common educational materials, let's finalize with precise terms.

Upon double-checking:

- Clue 8 Across: "an area found above the core; transports energy..." — this is specifically the Radiative Zone, but if the grid has 9 spaces, "Radiative" is 9 letters. "Zone" would be separate, but clue doesn't suggest that.

Perhaps the answer is "Radiative" implying the zone.

Similarly, for Down 4: "intense magnetic storms" — while sunspots are related, the term "storms" might point to Flares, but Flare is used in Across 10.

Conflict.

Alternative: Down 4 could be "Magnetic" but that's not a feature.

I recall that in some curricula, "sunspots" are described as areas of intense magnetic activity, so it's acceptable.

For Down 9: "stream of charged particles" — definitely Solar Wind. If the grid has 9 letters, "SolarWind" works.

Now, for Across 10: "tremendous explosion" — Flare is correct.

So, compiling final answers:

Final Answer:
Across: 6. Hydrogen, 7. Core, 8. Radiative, 10. Flare, 11. Convection, 12. Radiation
Down: 1. Photosphere, 2. Chromosphere, 3. Corona, 4. Sunspots, 5. Prominence, 6. Energy, 9. SolarWind

But to present neatly as per requirement:

Since the user needs the solved crossword, I'll list each answer corresponding to its number.

Note: In some versions, "Radiative Zone" might be expected, but given typical grid sizes, "Radiative" is often used for brevity in such puzzles.

Similarly, "Solar Wind" might be written as two words, but in crossword, it's combined.

To ensure accuracy, let's confirm with standard sources:

- Hydrogen: yes, 70-75% of sun's mass.
- Core: innermost, fusion occurs.
- Radiative Zone: energy transport via radiation.
- Flare: sudden explosion.
- Convection: energy transport method in convection zone.
- Radiation: emitted by sun.
- Photosphere: visible surface.
- Chromosphere: lower atmosphere.
- Corona: outer atmosphere.
- Sunspots: magnetic regions.
- Prominence: loop structures.
- Energy: from fusion.
- Solar Wind: particle stream.

All match.

So the final answers are:

Final Answer:
Across:
6. Hydrogen
7. Core
8. Radiative
10. Flare
11. Convection
12. Radiation

Down:
1. Photosphere
2. Chromosphere
3. Corona
4. Sunspots
5. Prominence
6. Energy
9. SolarWind
