Sand

In Minecraft, sand is a gravity-affected block found abundantly in deserts, beaches, and near surface water. Red sand, a variation, is exclusive to badlands biomes. While sand can be broken without tools, a shovel is the fastest method. Sand naturally generates in various biomes, typically in four-block-deep layers supported by sandstone, and as the ocean floor in warm ocean variants or covering buried treasure chests. Beyond construction, it's used to farm cacti, bamboo, sugarcane, and kelp. When unsupported, it becomes a 'falling block' entity affected by gravity, causing suffocation damage if it lands on players or mobs. It also becomes an item when landing on non-solid blocks. Sand is a component in making concrete powder and can be placed under note blocks to produce a 'snare drum' sound. Furthermore, sand is essential for building airlocks and suffocation traps in Minecraft. It's a versatile resource with diverse applications.
