Quartz movement is more traditional. Kintetic quartz relies on different principles and is a bit more accurate.

Yes, there are differences in the appearance and properties of these quartz types. Milky quartz has a cloudy white appearance due to trapped gas or fluid bubbles. Smoky quartz is a grayish-brown to black variety due to natural radiation exposure. Rose quartz is pink due to trace amounts of titanium, iron, or manganese.
The main difference between marine and freshwater ecosystems is the salt concentration in the water. Marine ecosystems have high salt concentrations, whereas freshwater ecosystems have low salt concentrations. This difference in salinity influences the types of organisms that can thrive in each ecosystem.
Salt (halite) is the most abundant mineral on Earth, followed by quartz. Silver is much less abundant in comparison.
Quartz is silicon dioxide (sand). Diamond is an allotropic form of carbon.

The difference between quartzite and quartz is that quartzite is a metamorphic rock formed from sandstone under heat and pressure, while quartz is a mineral composed of silicon and oxygen. In quartzite, the grains of sandstone have been recrystallized into a interlocking mosaic of quartz crystals, giving it a more durable and non-porous nature compared to quartz.

You can tell the difference in density between quartz and galena by measuring their mass and volume. Calculate the density by dividing the mass by the volume. Galena has a higher density than quartz, so the sample with higher density is likely to be galena.
Quartz is a mineral composed of silicon and oxygen atoms, while crystal is a general term used to describe a solid material whose atoms are arranged in a highly ordered repeating pattern. Quartz is a type of crystal, so all quartz is considered crystal, but not all crystals are quartz.
Quartz and glassy silica are both composed of the same elements in the same proportion. The difference is that in quartz is crystalline whereas glass is amorphous. This means that in quartz, the atoms are all ligned up in a regular repeating lattice. In glass, the atoms are arranged in a random way. This is analagous to the difference between a set of childrens blocks that have been stacked up nicely in regular rows, and blocks that are just dumped in a heap, and are arranged randomly.
