Approximately 3 kilometers large in diameter would the star Betelgeuse be on this same scale.

One of the biggest stars that can be seen with the unaided eye is a red supergiant star of the spectral class M1-2 called Betelgeuse. In the night sky, it is typically the tenth brightest star and, after Rigel, the second brightest star in the constellation of Orion. Betelgeuse is the most brilliant star in the darkened sky at near-infrared wavelengths.

If it were in the center of our solar system, Mercury, Venus, Earth, and Mars orbits and the asteroid belt would all be engulfed by its surface. Beginning in October 2019, Betelgeuse started to dramatically decrease, and by mid-February 2020, it had lost around three times as much light. No appreciable change in luminance over the previous 50 years was discovered by infrared measurements.

The main reason Mars has become geologically inactive compared to Earth is its smaller size and cooling rate.

Mars is significantly smaller than Earth, which means it has a smaller internal heat source from its core. Over time, the planet's internal heat has dissipated, causing its geological activity to decrease. On Earth, the larger size and higher heat production from the core sustain ongoing geological processes like plate tectonics and volcanic activity.

Additionally, Mars lacks the same level of tectonic activity as Earth. The absence of plate tectonics means that there are no active boundaries where crustal plates interact, leading to the formation of mountains, earthquakes, and volcanic activity. Plate tectonics play a crucial role in maintaining geological activity on Earth by recycling the crust and releasing heat from the interior.

Furthermore, Mars has a thinner atmosphere compared to Earth, resulting in reduced heat retention and less efficient transfer of energy. This leads to lower surface temperatures and limits the potential for geological processes that require higher temperatures, such as widespread volcanic activity.

Overall, the combination of Mars' smaller size, slower cooling rate, lack of plate tectonics, and thinner atmosphere are the main reasons why it has become geologically inactive in comparison to Earth.

The process of upwelling magma at divergent boundaries with subsequent movement away from those boundaries, and the return flow of cooled rock to deep in the mantle form cycles of slowly moving rock can be explained by mantle convection.

Mantle convection is driven by the heat transfer within the Earth's mantle. As the mantle undergoes heat transfer from the core, it experiences thermal expansion and becomes less dense.

This less dense material rises, creating upwelling currents of molten rock or magma at divergent boundaries, such as mid-ocean ridges. The upwelling magma then moves away from the divergent boundary, causing seafloor spreading.

On the other hand, the cooled rock at the Earth's surface becomes denser and sinks back into the mantle in a process known as subduction. This return flow of cooled rock completes the cycle of slowly moving rock within the mantle.

False. Most of the space occupied by a thin gold film is not taken up by the nuclei.

In fact, the majority of the volume in a thin gold film is occupied by the electron cloud surrounding the nuclei. Gold, like other metals, has a structure consisting of a regular arrangement of positively charged atomic nuclei surrounded by a sea of delocalized electrons.

The electrons are not tightly bound to individual nuclei and can move freely within the metal lattice. This arrangement gives metals their characteristic properties such as high electrical and thermal conductivity. In a thin gold film, the electron cloud extends throughout the entire volume of the film, occupying the space between the nuclei. Therefore, it is the electron cloud, rather than the nuclei, that occupies most of the space in a thin gold film.
