Craters
Craters. They are caused by the surface being hit by meteorites.

A round pit on the Moon's surface is typically referred to as a "lunar crater," which is formed by the impact of meteoroids, asteroids, or comets colliding with the Moon. These craters can vary significantly in size and can have raised rims and central peaks depending on their depth and the energy of the impact. Additionally, the Moon features various types of pits, such as "volcanic pits" or "lava tubes," which are formed by volcanic activity. Overall, these features provide insights into the Moon's geological history and surface processes.
Olives are one example of something specific with pits in it. The pits are the hard seed found inside the olive fruit.
Round depressions on the Moon are primarily impact craters, formed when meteoroids, asteroids, or comets collide with the lunar surface at high speeds. These impacts create circular pits, varying in size, with raised rims and sometimes central peaks. Over billions of years, the Moon's surface has accumulated numerous craters due to the lack of atmosphere and geological activity that would otherwise erode them. Some depressions may also be volcanic in origin, known as lava pits or calderas.
Pits and lands
The pits and flats are arranged in a spiral pattern on the CD. These pits and flats are found on the bottom edge of the CD and are the grooves that include data.
coated pits. :)
Compact Discs (CDs) store data on their surface using tiny pits and lands that are encoded in a spiral track. These pits represent binary data, with pits corresponding to binary "0" and lands representing binary "1." A laser in the CD player reads these variations in height as it spins the disc, allowing the retrieval of the stored information. The reflective layer beneath the surface helps in detecting the changes in light intensity caused by the pits and lands.
A lot of it has to do with the very top surface of the table. If you are using wood, there are many gaps and pits and grooves which can trap bacteria which then multiplies. Conversely, if you use glass there are fewer pits on the surface and it will be much easier to clean.
