Which statement best describes the principle of uniformitarianism? (Mark the one best answer.)
A
Deposition occurs faster today than it did in ancient environments.
B
Rocks form by the same processes today as in the past
C
Weathering and erosion can be fast or slow, depending on the type of rock.
D
Earth’s geological features were formed by a few catastrophic events.
Explanation: 

Detailed explanation-1: -Uniformitarianism says that the processes that shape Earth are the same throughout time. That means if we observe a process shaping Earth today, we can assume the same process shaped Earth in the past and will shape Earth in the future all over the planet and even on other planets.

Detailed explanation-2: -Uniformitarianism. The principle of uniformitarianism states that processes that alter the earth’s crust are the same processes that occurred millions of years ago. Furthermore, the results of processes today are the same as the results of the same processes millions of years ago.

Detailed explanation-3: -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-4: -Uniformitarianism is a theory based on the work of James Hutton and made popular by Charles Lyell in the 19th century. This theory states that the forces and processes observable at earth’s surface are the same that have shaped earth’s landscape throughout natural history.

Detailed explanation-5: -The principle of uniformitarianism is based on the idea that modern processes have operated throughout geologic time. According to the principle of uniformitarianism, processes have occurred at the same rates throughout geologic time.
