Question

Which among the following statements are correct with respect to inner and outer planets of the solar system?
1. Inner Planets have a thin, rocky crust.
2. Outer planets have a longer period of revolution
3. Inner Planets are called Jovian Planets.
4. Both 1 and 2

Answer 1

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.
