What is the cause and effect of tree roots that are exposed in cracks in your sidewalk?

Exposed tree roots in sidewalk cracks are typically caused by the growth of nearby trees seeking water and nutrients, which can lead to the roots pushing against the concrete as they expand. The effect of this phenomenon can include damage to the sidewalk, creating hazardous trip hazards and requiring costly repairs. Additionally, the disruption of the sidewalk can negatively impact drainage and water flow in the area.
