Why does Mercury (at 5.43 g/cm3 ) have a higher average density than the Moon (at 3.35 g/cm3 )? Venus may have a metallic core. New research, however, suggests that some of Venus' crust does get recycled, just through a radically different process—one that may have been active early in Earth's history. Another quality that Earth and Venus are thought to have in common is the internal structure below the surface. So it could easily have iron there.
Research suggests that each planet consists of an external crust, a thick layer of rock beneath it called the mantle and a molten core at the center. The correct answer choice is (B) The scientist quoted in this stimulus points out some of the similarities between Earth and Venus: Both planets have a hot molten core, and each needs to get rid of the excess heat that is generated by these molten cores. Why are features like the Moon's maria not observed on Mercury? The interior is not fully understood yet, however.
The critical temperature where Venus would start to solidify an inner core is 4940 ± 70 K. Please clarify, but to your current question, no. Inner core of Earth (and many other planets) are solid because of (what I think is pressure). Complete Question Explanation Resolve the Paradox. Similarly Venus’ core fluid temperature at its CMB, T M (P CMB), is approximately 3630 ± 15 K, but at the centre, the temperature is above T S (P centre) since Venus does not have an inner core.
Also, you said inner. As the solar system began to form about 4.5 billion years ago, planets were born from collisions of dust and rock. Mercury has the higher density because it has a large iron core while the Moon has a small iron core. Finally, if it is outer core you meant, and you didn't count the moon as a "planet", would you count extrasolar planets as "planets". Having a mean density of 3,346.4 kg/m³, the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core.This structure is believed to have resulted from the fractional crystallization of a magma ocean shortly after its formation about 4.5 billion years ago. If Lutetia does have a molten core, it would be the first asteroid known to be partially differentiated into a molten interior and cooler exterior, as Earth is. And the moon doesn't have any molten core.
Based on its density alone, Venus must have an iron-rich core that's at least partly molten — so why does it lack the kind of global magnetic field that Earth has?
