C60 fullerene has a lower density than diamond because of its molecular structure. C60 fullerene is composed of carbon atoms arranged in a spherical shape, with a relatively large amount of empty space within the structure. This results in a lower packing density compared to the tightly packed carbon atoms in the crystal lattice of diamond. Additionally, the carbon-carbon bonds in C60 fullerene are primarily double bonds, which are longer and weaker than the single bonds in diamond, contributing to its lower density. **

The popularity of cycling or skiing can vary depending on the location and time of year.
