A sand-to boulder-sized particle of debris in the solar system is called a meteoroid.
The boulder's size and shape change as it breaks down into smaller particles. The process of erosion gradually wears away the boulder's surface, breaking it apart into sand grains. This transformation involves physical and chemical weathering, which ultimately results in the boulder being transformed into sand.
since sand is ground up and very fine rock, i would imagine that it would be boulder.
Fine sand Course sand Gravel Boulder Solid rock
A quartz sand grain could combine with other rock particles to become sandstone which could then undergo metamorphism to become quartzite. Given enough time and weathering, it could simply become a part of a solution that reconstitutes elsewhere as part of a mineral crystal.
desert pavement
Gravel, cobble and boulder (in increasing order of size).
well that could be a problem but you could always travel north to become a boarder or could board on sand dunes if there are any around

a meteoroid is a rock from the size of a grain of sand to that of a boulder that is in our solar system
