Examples of casting in the following topics:
-
- Fossils can form under ideal conditions by preservation, permineralization, molding (casting), replacement, or compression.
- Later, the space may be filled with other sediments to form a matching cast in the shape of the original organism.
- Many mollusks (bivalves, snails, and squid) are commonly found as molds and casts because their shells dissolve easily .
-
- By growing higher than other plants, tall trees cast their shadow on shorter plants and limit competition for water and precious nutrients in the soil.
-
- While glia (or glial cells) are often thought of as the supporting cast of the nervous system, the number of glial cells in the brain actually outnumbers the number of neurons by a factor of ten.
-
- The material that the organism cannot digest is eliminated as feces, called castings, through the anus.
-
- Bones that are not subject to normal everyday stress (for example, when a limb is in a cast) will begin to lose mass.
