Consider the following statements regarding Solar System.
(A) Inner planets are made of gases and liquids whereas outer planets are made of rocks.
(B) Outer planets are bigger in size as compared to mner planets and some of the outerplanets have rings around them.
Choose the correct option.

Correct option is D

Statement (A) is false, but Statement (B) is true.

Statement (A):

This statement is false because the inner planets—Mercury, Venus, Earth, and Mars—are rocky planets, not made of gases and liquids. They are composed primarily of solid materials like metals and silicate rocks. These planets are also referred to as terrestrial planets due to their solid, rocky surfaces.

On the other hand, the outer planets—Jupiter, Saturn, Uranus, and Neptune—are made up primarily of gases and liquids like hydrogen, helium, methane, and ammonia. They are often referred to as gas giants (Jupiter and Saturn) and ice giants (Uranus and Neptune), with little to no solid surface. Hence, the statement about inner planets being made of gases and outer planets being made of rocks is incorrect.

Statement (B):

This statement is true. The outer planets are indeed significantly larger in size compared to the inner planets. For example, Jupiter, the largest planet, has a diameter about 11 times that of Earth. Furthermore, several outer planets have rings around them. Saturn is best known for its prominent ring system, but Jupiter, Uranus, and Neptune also have rings, though less visible. The inner planets do not have rings.

Information Booster:

·       Inner planets are also called terrestrial planets because of their rocky surfaces

·       Outer planets are classified as gas giants (Jupiter and Saturn) and ice giants (Uranus and Neptune).

·       Outer planets are much larger than the inner planets and possess ring systems and multiple moons.

·       Saturn has the most prominent and well-known ring system, but Jupiter, Uranus, and Neptune also have faint ring systems.

·       Inner planets are smaller and have fewer moons compared to the outer planets.

Additional Knowledge:

·       Inner planets: Mercury, Venus, Earth, and Mars are composed primarily of rock and metal and have solid surfaces.

·       Outer planets: Jupiter and Saturn are mostly composed of hydrogen and helium, while Uranus and Neptune contain gases like methane and ammonia. These planets are much larger and possess ring systems, with Saturn having the most visible rings.

·       Planetary Rings: The rings of the outer planets are made of particles of ice, rock, and dust. Saturn's rings are the most prominent, while the rings of Jupiter, Uranus, and Neptune are fainter and harder to observe.
