"Xenoliths" Natural Recordings by Native Speakers
Xenoliths are small fragments of rock that are incorporated into another rock. They can provide valuable information about the rock's composition, structure, and geochemical history. Xenoliths can be carried up from the Earth's mantle or lower crust and brought to the surface by volcanic activity, resulting in inclusions in volcanic rocks.
Xenohormesis is a phenomenon where exposure to small amounts of toxins or stressors that would be harmful to one species can elicit adaptive benefits or protective responses in another species.
