Uniformitarianism is the principle that the same geological processes we observe today have always been at work throughout Earth's history.
均变论是指地球历史中始终存在我们今天所观察到的同一地质过程的原则。
The theory of uniformitarianism was first proposed by James Hutton in the late 18th century.
均变论是由詹姆斯·赫顿在18世纪末首次提出的理论。
Uniformitarianism suggests that the Earth's features are the result of long-term natural processes, rather than catastrophic events.
均变论认为地球的特征是长期自然过程的结果，而不是灾难性事件。
Despite initial skepticism, uniformitarianism has become widely accepted in the scientific community as a fundamental concept in geology.
尽管最初遭到怀疑，但均变论在科学界已成为地质学中的一个基本概念，并被广泛接受。
In contrast to catastrophism, uniformitarianism emphasizes the gradual and ongoing nature of geological change.
与灾变论相比，均变论强调地质变化的渐进性和持续性。
Uniformitarianism helps scientists understand how the Earth's landscapes and rock formations were created over millions of years.
均变论帮助科学家理解地球上数百万年来是如何形成景观和岩石结构的。
This principle is crucial for dating rocks and fossils using relative and absolute dating techniques.
这一原理对于使用相对和绝对年代测定技术为岩石和化石定年至关重要。
Uniformitarianism has important implications for environmental studies, as it suggests that human activities can have long-lasting impacts on the Earth's systems.
均变论对环境研究具有重要意义，因为它表明人类活动可能对地球系统产生持久的影响。
The application of uniformitarianism in paleontology allows researchers to reconstruct past environments and ecosystems.
在古生物学中应用均变论使研究人员能够重建过去的环境和生态系统。
Critics argue that uniformitarianism oversimplifies complex geological processes and may not account for sudden, large-scale events.
批评者认为，均变论过于简化了复杂的地质过程，并且可能没有考虑到突然的大规模事件。
