Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is Jupiter so much larger than Earth? Check all that apply.
A
Inner planets were created at higher velocities.
B
Outer planets have less gravity than inner ones.
C
Outer planets attracted helium, hydrogen, and other gasses.
D
Inner planets formed where temperatures were cooler.
E
Gases escaped from inner planets and not from outer ones.
Explanation: 

Detailed explanation-1: -Why are the outer planets more gaseous than the inner planets? Because they formed in the cooler region of the solar nebula and therefore did not loose their lighter gases. Because they have their gases they are not as dense as the inner planets.

Detailed explanation-2: -Inner planets are smaller than outer planets because they are closer to the Sun. The outer planets, like Uranus and Neptune, which are further from their stars have weaker gravity than the inner planets. The vast space and gravity of the Sun within the outer planets allowed the outer planets to grow massively.
