---

Question 6:
*The galaxy that contains our solar system.*
→ We live in the Milky Way galaxy.
✔ Correct answer: B. milky way

---

Question 7:
*The repeating path an object takes around another object.*
→ That’s called an orbit — like Earth’s orbit around the Sun.
✔ Correct answer: D. orbit

---

Question 8:
*One complete orbit of earth around the sun is called a revolution.*
→ Yes! One trip around the Sun = one year = one revolution.
✔ Correct answer: B. revolution

---

Question 9:
*A large hole in the ground that is shaped like a bowl.*
→ That’s a crater — made by impacts from meteors or volcanoes.
✔ Correct answer: B. crater

---

Question 10:
*Rise and fall of the ocean (water level) due to the moon’s gravity.*
