Building on the Ideas First Proposed by James Hutton, Charles

Building on the ideas first proposed by James Hutton, Charles Lyell aimed to explain Earth's geological features using an approach known as uniformitarianism, which hypothesized that

A) large-scale geological events abruptly shaped the surface of Earth.
B) all geological processes operate in a sporadic manner and vary in their rate of change.
C) observable geological processes rapidly change Earth's surface, greatly impacting organisms living in the region of change.
D) the same geological processes currently observable operate over very long periods of time in a slow and gradual manner.
