Question

Какими физическими характеристиками планеты-гиганты резко отличаются от планеты земной группы?

Answer 1

1-Планеты гиганты имеют газовую оболочку.
2-Планеты гиганты имеют кольца(но они видны только у Юпитера).
3-Планеты гиганты имеют очень низкую температуру (от -2000)
4-Планеты гиганты намного больше планет земной группы.

Answer 2

Physical Characteristics of Giant Planets vs. Terrestrial Planets

Giant planets, such as Jupiter and Saturn, have several physical characteristics that sharply distinguish them from terrestrial planets like Earth.

1. Size and Mass: - Giant planets are significantly larger and more massive than terrestrial planets. They are often referred to as "gas giants" due to their predominantly gaseous composition, in contrast to the rocky composition of terrestrial planets.

2. Composition: - Giant planets are primarily composed of hydrogen and helium, with a small rocky core at their center. In contrast, terrestrial planets are predominantly rocky with a metallic core.

3. Atmosphere: - Giant planets have thick atmospheres consisting of hydrogen, helium, and other compounds, which give them their characteristic banded appearance. Terrestrial planets have much thinner atmospheres, with Earth's atmosphere being predominantly composed of nitrogen and oxygen.

4. Magnetic Field: - Giant planets have strong magnetic fields, generated by the motion of electrically conducting fluids in their interiors. In comparison, terrestrial planets generally have weaker magnetic fields, with Earth being an exception due to its active iron core.

5. Rings: - Giant planets, such as Saturn, are known for their prominent ring systems, which are not present around terrestrial planets.

In summary, the physical characteristics that distinguish giant planets from terrestrial planets include their size, composition, atmosphere, magnetic field, and the presence of ring systems.
