Final answer:
Lightning is an example of natural plasmas, consisting of ionized gases that are created under high-temperature conditions like those in lightning strikes.
Step-by-step explanation:
An example of plasmas in nature is lightning. Plasma is considered the fourth state of matter, distinct from solids, liquids, and gases. Plasma consists of a hot ionized gas with electrons that have been separated from their nuclei, resulting in a mixture of free electrons and positive ions. Natural plasmas can be observed in the interiors of stars, as well as in phenomena such as lightning strikes on Earth. Due to the high temperatures and energies involved, the gaseous substances become ionized and exhibit the unique properties of a plasma state.
