Question

When viewed from space:
1. Earth looks as blue sphere
2. Mars looks like a red planet
3. Neptune has rings
Which of the following statements is/are correct?
A. 1 only
B. 2 only
C. 1 and 2
D. 2 and 3

Answer 1

Hint: Neptune has multiple satellites but no rings. The planet associated with that characteristic is Saturn. This knowledge helps us already come down to two options. Now think of etymology and portrayal of the solar system in pop culture for indicators for the other two.

Complete answer: Option C is correct.
-Earth has often been described as a blue planet, as 71% of its surface is water, making it seem this way from outer space. It is the third planet away from the sun, and is the only one in our solar system with life on it.
-Mars comes after Earth, and is the second-smallest planet in the solar system. It appears red because of the high dust content in its atmosphere. The iron oxide or rust in its soil also contributes to this image. The surface does show other colors like tan, brown and gold. It also has the biggest volcano in the system, which is three times the size of Mount Everest.
-Neptune has the strongest winds in the solar system and is the farthest from the sun. Its named after the Roman God of the sea and is the coldest.

Therefore, The correct answer is Option C ie. 1 and 2.

Note: Mars was named after the Roman god of war, as it reminded astronomers of blood and violence because of its color. Even the Egyptians called it ‘the red one’ or ‘her desher’. Earth is derived from ‘erda’, which meant ground or soil when the Anglo-Saxons/Germans spoke.
