Uniformitarianism
The laws of physics, such as gravity and thermodynamics, have remained constant throughout geological time. Similarly, the principles of chemistry, including the conservation of matter and energy, have also operated in the past. Biological laws, such as evolution and genetics, have shaped life on Earth both in the past and present.
Uniformitarianism is the principle that the same natural laws and processes that operate in the present have always operated in the past. In other words, it suggests that geological and biological processes that occur on Earth today have occurred in the same way throughout its history. This principle is central to the science of geology and helps scientists understand past events and phenomena.
The principle of uniformitarianism helps geologists understand Earth's past by suggesting that the processes observed today, such as erosion or volcanic activity, have also operated in the past at a similar rate and intensity. By studying these present-day processes, geologists can infer what processes may have influenced the geologic features of the past, aiding in reconstructing Earth's history.
The principle is known as Uniformitarianism, which posits that the same geological processes observed today (such as erosion, sedimentation, plate tectonics) have been at work in the past and have shaped Earth's landscape over millions of years. This principle was popularized by geologist James Hutton in the 18th century.
Another term often used as a synonym for uniformitarianism is actualism. Both concepts suggest that geological processes have operated in the same way over time and can be used to interpret past events.

This is the doctrine of dual sovereigns.
The statement relates to the principle of uniformitarianism, which posits that the processes shaping the Earth today, such as erosion, sedimentation, and biological activity, have operated in a similar manner throughout geological history. This principle suggests that by studying current geological and biological processes, we can infer how past environments and landscapes were formed. It underpins much of modern geology and paleontology, providing a framework for understanding Earth's history.
The US operated on the Truman Doctrine, which was that communism must be contained, and thereby prevented from taking over the world.
Hutton's observations led him to develop the idea of uniformitarianism, which states that the same geologic processes at work today have been shaping the Earth's surface over immense spans of time. This concept laid the foundation for the modern understanding of geological processes and helped shape the science of geology.
