Solved The Solar System The Sun Understanding Main Ideas | Chegg.com - Free Printable

Let's solve this step by step. The image is a worksheet about the Sun, with two parts:

1. Labeling the diagram of the Sun (with numbers 1–6).
2. Matching vocabulary terms (7–17) with their correct descriptions (a–k).

🔹 Part 1: Label the Diagram of the Sun

We are given a cross-sectional diagram of the Sun with numbered lines pointing to different parts.

Here’s how we identify each part based on standard solar structure:

1. Outermost layer of the atmosphere – This is the corona.
2. Layer below corona, visible as surface glow – This is the chromosphere.
3. The visible surface of the Sun – This is the photosphere.
4. The outermost layer of the Sun's interior (just below photosphere) – This is the convection zone.
5. The inner layer where energy moves by radiation – This is the radiation zone.
6. The center of the Sun – This is the core.

So, labeling:

1. Corona
2. Chromosphere
3. Photosphere
4. Convection zone
5. Radiation zone
6. Core

🔹 Part 2: Matching Vocabulary Terms

Now match the terms (7–17) with the correct lettered descriptions (a–k).

Let’s go through each term and find its matching description.

#### 7. solar flare
→ f. eruptions that occur when the loops in sunspot regions suddenly connect
✔️ Solar flares are sudden bursts of energy caused by magnetic reconnection in sunspot areas.

#### 8. core
→ h. the center of the sun
✔️ The core is the central region where nuclear fusion occurs.

#### 9. chromosphere
→ b. the layer of the sun’s atmosphere that has a reddish glow
✔️ Chromosphere appears reddish during solar eclipses.

#### 10. sunspot
→ d. areas of gas on the sun’s surface that are cooler than the gases around them
✔️ Sunspots are dark spots due to strong magnetic fields reducing surface temperature.

#### 11. corona
→ c. the layer of the sun’s atmosphere that looks like a halo during an eclipse
✔️ Corona is the outer atmosphere visible as a white halo during total solar eclipses.

#### 12. nuclear fusion
→ j. the joining of hydrogen atoms to form helium
✔️ Fusion in the core converts hydrogen into helium, releasing energy.

#### 13. photosphere
→ a. the layer of the sun’s atmosphere that gives off visible light
✔️ Photosphere is the visible "surface" of the Sun; it emits most of the light we see.

#### 14. solar wind
→ g. a stream of charged particles produced by the corona
✔️ Solar wind consists of electrons and protons streaming from the corona into space.

#### 15. prominence
→ e. reddish loops of gas that link parts of sunspot regions
✔️ Prominences are large arches of plasma extending from the Sun’s surface, often linked to sunspots.

#### 16. radiation zone
→ k. the layer of the sun’s interior where energy is transferred mainly by electromagnetic radiation
✔️ In the radiation zone, energy moves via photons (radiation), not convection.

#### 17. convection zone
→ i. the outermost layer of the sun’s interior
✔️ Convection zone lies just beneath the photosphere and is where energy moves via convection currents.
