Some geysers have surprisingly regular eruption intervals, like Old Faithful in Yellowstone, which erupts approximately every 44 to 125 minutes, demonstrating a natural clockwork mechanism driven by hydrothermal processes.

Some geological processes create natural nuclear fission reactors, such as the Oklo mine in Gabon, Africa, which was active almost 2 billion years ago, demonstrating naturally occu...

The 'Mount Yasur' volcano on Tanna Island, Vanuatu, has been erupting almost continuously for at least 800 years, making it one of the most persistently active volcanoes on Earth.

Some rocks exhibit triboluminescence, emitting light when fractured, scratched, or rubbed, a phenomenon not fully understood but observed in minerals like quartz and sphalerite.

Some minerals, like 'uraninite,' are naturally radioactive and undergo continuous decay, releasing energy and sometimes causing surrounding rocks to glow faintly over long periods.

The formation of the Himalayas is ongoing, with the Indian Plate still pushing northward into Asia at a rate of approximately 2 cm (0.8 inches) per year, causing continued uplift a...
