GENERAL GEOLOGY

Detailed explanation-1: -The principle of uniformitarianism says that the present is the key to the past.

Detailed explanation-2: -In geology, uniformitarianism has included the gradualistic concept that “the present is the key to the past” and that geological events occur at the same rate now as they have always done, though many modern geologists no longer hold to a strict gradualism.

Detailed explanation-3: -The statement “The present is the key to the past” was made by James Hutton, which is known as Uniformitarianism. Charles Lyell’s Principles of Geology was published between 1830-1833, and introduced the famous maxim, ‘the present is the key to the past’.

Detailed explanation-4: -The idea that the same natural laws and processes that operate on Earth today have operated in the past is an assumption many geologists use in order to better understand the geologic past. This idea is known as uniformitarianism, also defined as “the present is the key to the past”.
