Correct Answer - Option 4 : Both 1 and 2

The Correct Answer is Option 4 i.e Both 1 and 2.

  • Inner Planets:
    • Inner planets are represented as the planets between the sun and the belt of asteroids i.e Mercury, Venus, Earth, and Mars.
    • Inner planets (Mercury, Venus, Earth, and Mars) are called terrestrial planets because their structure is similar to the earth.
    • Inner Planets have a thin, rocky crust. Hence, Option 1 is correct.
    • They are nearer to the sun.
    • They move faster and have a shorter period of revolution.
  • Outer Planets:
    • Outer planets are represented as the planets after an asteroid belt i.e Jupiter, Saturn, Uranus, and Neptune.
    • Outer planets (Jupiter, Saturn, Uranus, and Neptune) are called Jovian planets. Hence, Option 3 is NOT correct.
    • Outer planets are all gaseous bodies.
    • They are far away from the sun.
    • Jupiter is the biggest and mercury is the smallest planets of our solar system.
    • They move rather slowly and have a longer period of revolution. Hence, Option 2 is correct.
