In volcanic rocks, it may be gas bubbles. Otherwise, it may be where certain minerals are more susceptible to solution and erosion.

La Bara Tar Pits has almost all tar pits outside on the gates
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.
Metamorphic rocks form when existing rocks are subjected to high temperature and pressure conditions deep within the Earth's crust. This causes the minerals in the original rock to recrystallize and change their structure, resulting in the formation of metamorphic rocks.
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.
Deep pits in the skin can be caused from scars. For instance, acne scars can cause deep pits in the skin.
Uneven watering.
It is abrasion
Near rocks, and in small sand pits filled with water, especially in seaweed
Common causes of pits in granite countertops include natural fissures in the stone, improper sealing, and impact damage. Potential solutions include filling the pits with epoxy or resin, resealing the countertop regularly, and avoiding placing hot items directly on the surface.
No, its erosion that causes rocks to change
Water erodes rocks by taking away little bits, and water gets into the little pits of a rock, and when it freezes, the water expands and makes the pits/cracks bigger. Over time, this breaks the rocks down.
Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
Deformed, and change into metamorphic rocks.
When plate movement causes rocks to break it is call an earthquake.
Heat and pressure.
