Let’s go step by step to solve each question.

Question 1: Put the names of the planets in order.

We are shown four planets from left to right:

- First (smallest, gray, cratered) → Mercury
- Second (yellowish-white, cloudy) → Venus
- Third (blue and white with continents) → Earth
- Fourth (reddish-orange) → Mars

So the correct order from left to right is:
Mercury, Venus, Earth, Mars

The answer boxes below should be filled in that order under the corresponding planet images.

Question 2: What is rotation?

Rotation means spinning around an axis — like a top or a basketball on your finger.

For Earth, rotation is when it spins on its own axis (an imaginary line through the North and South Poles).

Looking at the options:

A. Earth spinning on its Axis → ✔ Correct
B. Earth going around The Sun → That’s revolution, not rotation
C. The moon going around the Earth → That’s lunar orbit
D. The earth staying still → Not true — Earth moves!

✔ So the answer is A

Question 3: How long does rotation on earth last?

One full spin of Earth on its axis takes about 24 hours — that’s why we have day and night every 24 hours.

Options:

A. About 30 days → Too long (that’s roughly a month)
B. 60 minutes → Way too short (just 1 hour)
C. 24 hours → ✔ Correct
D. 365 days → That’s one year (revolution around the Sun)

✔ Answer: C

Question 4: What does rotation cause?

Because Earth rotates once every 24 hours, different parts face the Sun (day) and then turn away (night).

So rotation causes day and night.

Options:

A. A year → Caused by revolution around the Sun
B. Season → Also caused by tilt + revolution
C. Day and night → ✔ Correct
D. A month → Related to Moon’s orbit

✔ Answer: C
