Quiz on the difference and similarities of inner and outer planets
Quiz Preview
- 2.
Jupiter, Saturn, Uranus, and Neptune are the outer planets?
-
True
-
False
Correct Answer
A. TrueExplanation
Jupiter, Saturn, Uranus, and Neptune are considered the outer planets because they are located beyond the asteroid belt in our solar system. These planets are much larger in size compared to the inner planets (Mercury, Venus, Earth, and Mars) and are primarily composed of gas. They also have longer orbital periods and are known for their distinct ring systems and numerous moons. Therefore, it is correct to say that Jupiter, Saturn, Uranus, and Neptune are the outer planets.Rate this question:

Characteristics that inner planets have in common are?
Correct Answer
rocky, small and closest to the sunExplanation
The inner planets, including Mercury, Venus, Earth, and Mars, share several common characteristics. Firstly, they are all composed mainly of rocky material, with solid surfaces and a dense composition. Secondly, they are relatively small in size compared to the outer gas giants. Lastly, they are located closest to the sun in our solar system. These shared characteristics distinguish the inner planets from the outer planets, which are larger, composed mostly of gas, and located farther away from the sun.Rate this question:

Are inner planets smaller or larger than outer planets?
-
Smaller
-
Larger
Correct Answer
A. SmallerExplanation
Inner planets are smaller than outer planets because inner planets are closer to the sun and therefore experience higher temperatures and greater gravitational forces. These conditions prevent the inner planets from accumulating as much gas and dust during their formation, resulting in smaller sizes compared to the outer planets. Additionally, the outer planets are predominantly composed of gas, making them much larger in size.Rate this question:

List the inner planets in order from smallest to largest?
Correct Answer
Mercury, Mars, Venus, EarthExplanation
The inner planets are listed in order from smallest to largest. Mercury is the smallest inner planet, followed by Mars, Venus, and Earth, which is the largest among them.Rate this question:
- 6.
The outer planets consist of gas instead of rock?
-
True
-
False
Correct Answer
A. TrueExplanation
The outer planets, also known as gas giants, are composed mainly of gases such as hydrogen and helium, rather than solid rock. These planets, including Jupiter, Saturn, Uranus, and Neptune, have thick atmospheres and lack a solid surface. The immense gravitational forces in these planets compress the gases to form a dense core, surrounded by layers of gas. Therefore, it is true that the outer planets consist of gas instead of rock.Rate this question:

The inner and outer planets are seperated by?
-
Jupiter's great storm
-
Earth and its moon
-
Saturn and its ring
-
The asteroid belt
Correct Answer
A. The asteroid beltExplanation
The inner and outer planets are separated by the asteroid belt. This region, located between the orbits of Mars and Jupiter, is filled with numerous small rocky objects called asteroids. These asteroids are remnants from the early formation of the solar system and never formed into a planet due to the gravitational influence of Jupiter. The asteroid belt acts as a barrier between the inner rocky planets (Mercury, Venus, Earth, and Mars) and the outer gas giant planets (Jupiter, Saturn, Uranus, and Neptune).Rate this question:
