Answer: Fossils
Step-by-step explanation:
When an igneous rock forms, all the material it contains is destroyed and melted by extreme heat. For this reason, igneous rocks don’t contain any fossils.
Igneous rocks are formed from the cooling and solidification of molten rock, also known as magma or lava. The intense heat and pressure of the molten rock destroys any organic matter that may have been present in the original rock.
