Sidewalks and bridges and other material that must hold heavy traffic require periodic breaks in order to prevent the material from cutting and breaking at will
Sidewalk elves of course! Some of them are buried in the concrete to this day.
They may be striving to lay claim to that unattended quarter on the sidewalk. They might be trying to get the larger piece of shade on the sidewalk, if it is summertime. They be be experiencing a clash of the titanic egos.
The separation between squares of sidewalk cement is usually referred to as a crack, although I think that gap might be more accurate.

The roots of the grass may further widen the crack in the sidewalk as it grows, causing potential trip hazards. Additionally, as the grass grows, it can retain moisture which may lead to further deterioration of the sidewalk over time. If left unchecked, the grass can also make the sidewalk more slippery when wet.
The new stadium might be built downtown. Our new house might be built on the lakefront. The new dorm might be built near the student union.
Properly designed sidewalks have an expansion strip every so often. Since the materials used to make sidewalks can expand and contract with heat and cold, these expansion strips act as "cushions" to each section of the sidewalk. If the expansion strips are incorrectly installed, or damaged, it is possible for the sidewalk sections to buckle and/or crack. If you need to have your sidewalk repaired, make sure that the contractor properly installs expansion strips, usually by filling the gap with foam backer rod topped with a urethane sealant.

Okay, so think about it. If a sidewalk was not built with cracks in it, then eventually weathering and erosion would cause cracks anyway. Then, whenever it rained, rainwater would get in the cracks. Stay with me now! If the temperature then dropped below the freezing point (32 degrees F, 0 degrees C), then the water in the cracks will freeze. When water freezes, it expands, which would exert pressure on the sidewalk, eventually causing the sidewalk to further crack or even split in two! If a sidewalk already has minimal, purposefully placed cracks in it, then the damage can be minimized.
Adults are generally not allowed to ride on the sidewalk. But the laws aren't the same everywhere, so there's no definite answer. Local regulations might apply. You really have to check what goes for where you live.
