Question

: Which of the following statements is correct?
A. Jupiter and Saturn are lighter than earth.
B. Jupiter and Saturn have no natural satellites.
C. Jupiter and Saturn are gaseous giants.
D. Jupiter and Saturn have rings.

Answer 1

Hint:The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. The eight planets are the largest of the objects that orbit the Sun directly, with the dwarf planets and other Solar System entities making up the rest.

Complete answer:
(i) Jupiter > Saturn > Uranus > Neptune > Earth > Venus > Mars > Mercury are the planets in order of decreasing size. As a result, the statement that Jupiter and Saturn are lighter than Earth is incorrect.
(ii) Jupiter is our solar system's largest planet and the first of the gas giant planets. Jupiter has 63 moons and a ring system that is barely visible.
(iii) Saturn, the sixth planet from the sun, is also a gas giant, with a huge and complicated ring system as its most striking feature when seen from afar. Saturn's interior, like Jupiter's, contains mainly hydrogen and helium.
(iv) Jupiter, Saturn, Uranus, and Neptune are known as the outer planets because they are far from the sun and contain a ring system and a high number of moons.

Henec, the correct statements are C and D.

Note:Jupiter and Saturn are largely made up of hydrogen and helium, with heavier elements accounting for 3 to 13% of their mass. They're expected to have a molten rocky core and an exterior layer of molecular hydrogen enclosing a layer of liquid metallic hydrogen. Many layers of visible clouds, largely made of water and ammonia, characterise the outermost portion of its hydrogen atmosphere. The metallic hydrogen layer, which makes up the majority of each planet, is called "metallic" because the extremely high pressure turns hydrogen into an electrical conductor.
