A line segment on a graph would be any line that isn't continuous. It would have dots on the ends instead of arrows. Is that what you're asking?
Answer:
D. Because there was more gas farther from the Sun. As the are out of the range
Explanation:
- Basically, due to the core acceleration mechanism, theory to the formation of gaseous objects that can pull the gas as farther away from the sun the impact of solar winds is quite less. There are low-pressure regions
- Unlike rocky planets that have a different atmosphere and gas giants don't have a well-defined surface there atmosphere simply becomes denser to the core which may also be in a liquid-like state thus not suitable for landing.
- There are four gaseous giants in our solar system such as Uranus, Neptune, Jupiter Saturn all have atmosphere covered with ice or gases and all are bigger as compared to terrestrial planets like earth thus they are called as Jovian planets.
- These Jovians attract large amounts of gas as their magnetic fields are stronger and huge size ad gas giants are known as metallic molecules of hydrogen and helium in core consisting of more than 50% of the planet masses.
The heat that remains inside the Earth from its creation and radioactive decay are its main heat sources.
The deep earth receives heat from three main sources: (1) heat left over from the planet's formation and accretion, (2) frictional heating brought on by denser core material sinking to the planet's centre, and (3) heat from radioactive element decay.
The energy produced when unstable atoms decay is known as radioactivity, and it is a substantial contributor to the Earth's heat. The main source are the radioactive isotopes of uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in the Earth's mantle.
