Hundreds of millions of years
More like over 4 billion years - that's the approximate age of planet Earth.
There is evidence for life on earth at least some 3,600 million years ago. So the answer is non of the above but "thousands" of millions of years.

To convert hundreds of thousands to millions, you divide by 10. Since 60 hundreds of thousands is equivalent to 60 x 100,000, that equals 6,000,000. Therefore, 60 hundreds of thousands is 6 million.

The formation of buttes occurs on a geological timescale. This can be from millions to hundreds of millions years.

An eon is the largest division of geologic time, lasting billions of years. An era is a subdivision of an eon, typically lasting hundreds of millions of years. A period is a smaller division of geologic time, lasting millions of years, and an epoch is an even smaller division of time, typically lasting tens of millions of years.
Eons are the largest division of geologic time, typically lasting hundreds of millions to billions of years. They are used to represent the greatest expanse of time in Earth's history.
A paleontologist might use a geologic timescale clock, which shows the Earth's history in a chronological order based on rock layers and fossil records. This allows them to track the evolution and extinction of species over millions of years.
Not just hundreds of millions. The observable universe contains hundreds of billions of galaxies.
Oil and gas have been forming in the Earth's crust for millions of years, with some reservoirs dating back to hundreds of millions of years. The process involves the organic remains of marine plants and animals being transformed under high pressure and temperature over geologic timescales.
