Big cracks in the sidewalk can be caused by a variety of factors, such as tree roots pushing up underneath the concrete, soil erosion beneath the sidewalk, or the natural settling of the ground over time. Changes in temperature, especially freeze-thaw cycles, can also contribute to cracking by expanding and contracting the concrete.

Sidewalk Cracks
Is cracks on a sidewalk next to a tree physical or chemical weathering?
Cracks on a sidewalk next to a tree are primarily caused by physical weathering. The tree roots grow and expand, exerting pressure on the sidewalk, which eventually causes it to crack. This is a mechanical process rather than a chemical one.
What would happen to a sidewalk on a hot day if there were no cracks?
If a sidewalk had no cracks on a hot day, it could potentially expand due to the heat. The lack of cracks would prevent the sidewalk from accommodating this expansion, potentially causing it to buckle or warp. This could lead to damage and make the sidewalk uneven or unsafe for pedestrians.

sidewalks crack in the winter because the frost gets into tiny cracks in the sidewalk and as they expand, they cause the cracks to get bigger.
Why does a sidewalk have built in cracks every few feet?
It is because if it was one big piece, the concrete would buckle and break just like bridges.
Why are sidewalks are usually built with cracks in them?
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.
Why is it bad luck walking on sidewalk cracks?

When a tree cracks a sidewalk is it weathering?

You can also pour boiling water or vinegar into the cracks to kill the grass. Regularly maintaining the cracks by pulling out any new growth can help prevent grass from growing back.
