Let’s go through each question one by one and pick the correct answer.
---
Question 1: What is at the center of our solar system?
The solar system includes the Sun, planets, moons, asteroids, comets, etc. The Sun is the biggest object and everything else orbits around it. So, the center is the Sun.
✔ Correct answer:
the sun
---
Question 2: Earth travels in a(n):
Earth doesn’t move in a perfect circle — its path is slightly stretched out, like an oval. That shape is called an ellipse. Scientists call this an “elliptical orbit.”
✔ Correct answer:
elliptical orbit.
---
Question 3: One complete Earth orbit of the sun is called:
When Earth goes all the way around the Sun once, that takes about 365 days — we call that one year. In science terms, that full trip is called a “revolution.” (Rotation is when Earth spins on its axis — that’s what gives us day and night.)
✔ Correct answer:
a revolution.

Question 4: How long does it take for the Earth to orbit the sun?
As mentioned above, it takes about 365 days for Earth to go around the Sun once. That’s why we have a calendar year with 365 days (and every 4 years we add a leap day).
✔ Correct answer:
about 365 days
---
Question 5: The Earth rotates on its:
Earth spins like a top. The imaginary line it spins around is called its “axis.” It tilts a little bit, which helps give us seasons. Poles are the ends of the axis, but the spinning happens *on* the axis.
✔ Correct answer:
axis.

Final Answer:
1. the sun
2. elliptical orbit.
3. a revolution.
4. about 365 days
5. axis.
