Uniformitarianism states that
the Earth is uniform throughout its interior. the Earth's mantle is uniform, although it is different from the crust and core. geologic change occurs over long periods of time by a sequence of almost imperceptible events. catastrophic events such as volcanic eruptions alter the Earth. |
