Hollow spheres in limestone rock are called vugs. Vugs are formed when a cavity in the rock is later filled with minerals or crystals. They can vary in size and shape and are often sought after by collectors for their unique beauty.
A fossil cast is a type of fossil formed when sediments fill in the hollow space left by a decomposed organism. The sediments harden into rock, preserving the shape of the organism in the form of a cast. This can provide scientists with valuable information about the size and shape of the original organism.
A fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
Geodes. They can be found in some igneous rocks as well. They start as a hollow cavity created by a gas bubble or decaying organism. Mineral rich water seeps into the cavity and crystals form from the outside toward the inside.
Hollow rocks are formed through a process called weathering and erosion. Over time, natural forces like wind, water, and ice wear away at the rock, creating hollow spaces inside. This process can be accelerated by factors like chemical weathering or the presence of cracks in the rock.
