What is pitch? plz explain in full depth

The highness or lowness of a sound. Octave. The distance between A and the next-higher or next-lower A

Pitch is how high or low a sound is. for example, on a piano, the keys on the right side are a lot higher, meaning that the pitch is high. on the left side the sound produced is a lot lower, so the pitch is low. if you’re talking about those on a music sheet or score, those that are higher up on the score have a high pitch, while those on the lower end of the score have a low pitch. if the question states increasing in pitch, you simply observe the pattern in the musical notes. if it goes upwards it is increasing in pitch (getting higher) but if it’s going down it’s decreasing (getting lower)!

What’s the question

If you are talking about typical sand you would find at the beach or in a river bed here on earth, there are some differences. i would say the first biggest difference is in composition and mineral make up. although the moon is largely made of the same materials as earth’s mantle and surface, the moon experiences very little weathering (no liquid water and virtually no atmosphere). “earth” sand is typically composed mostly of quartz grains. this is because quartz is highly resistant to both physical and chemical weathering. most of the other minerals originally with the quartz are broken down into fine clay and carried away, chemically eroded/ dissolved, or some combination of the two. this usually leaves only the quartz behind, and so most of the time when you see/think of sand, you are talking about quartz. without these weathering mechanisms on the moon, the “sand” (which is likely more silt or clay sized grains anyways) would consist of mostly other minerals like anorthosite, olivine, and proxene.
