Educational worksheet illustrating the Solar System with space to label planets and circle inner and outer planets.

The image provided is a worksheet about the Solar System, where students are asked to label the planets and identify the inner (terrestrial) and outer (Jovian) planets. Below is the solution with an explanation:

Solution:

#### Step 1: Label the Planets
The diagram shows the orbits of the planets around the Sun. The order of the planets from the Sun outward is as follows:

1. Mercury
2. Venus
3. Earth
4. Mars
5. Jupiter
6. Saturn
7. Uranus
8. Neptune

Using this order, we can label the planets in the diagram:

- A: Mercury
- B: Venus
- C: Earth
- D: Mars
- E: Jupiter
- F: Saturn
- G: Uranus
- H: Neptune
- I: Pluto (Note: Pluto is no longer classified as a planet but is included here for historical context.)

#### Step 2: Identify the Inner Planets (Terrestrial)
The inner planets are the four rocky planets closest to the Sun. These are:
- Mercury
- Venus
- Earth
- Mars

In the diagram:
- A: Mercury
- B: Venus
- C: Earth
- D: Mars

These should be circled in blue.

#### Step 3: Identify the Outer Planets (Jovian)
The outer planets are the four gas giants farther from the Sun. These are:
- Jupiter
- Saturn
- Uranus
- Neptune

In the diagram:
- E: Jupiter
- F: Saturn
- G: Uranus
- H: Neptune

These should be circled in red.

Final Answer:

1. Labels for the Planets:
- A: Mercury
- B: Venus
- C: Earth
- D: Mars
- E: Jupiter
- F: Saturn
- G: Uranus
- H: Neptune
- I: Pluto

2. Circle the Inner Planets (Terrestrial) in Blue:
- A (Mercury)
- B (Venus)
- C (Earth)
- D (Mars)

3. Circle the Outer Planets (Jovian) in Red:
- E (Jupiter)
- F (Saturn)
- G (Uranus)
- H (Neptune)

Explanation:

- Terrestrial Planets: These are the inner, rocky planets (Mercury, Venus, Earth, Mars). They are smaller and denser compared to the outer planets.
- Jovian Planets: These are the outer, gas giants (Jupiter, Saturn, Uranus, Neptune). They are larger and primarily composed of gases like hydrogen and helium.

By following the order of the planets from the Sun outward, we can accurately label them and categorize them into terrestrial and Jovian groups.
