Passage 1: Blood Falls, Antarctica

Blood Falls is a five-story waterfall located at the Taylor Glacier in Antarctica. Its striking red color comes from iron-rich saltwater that oxidizes when it contacts the air. Scientists discovered that the water has been trapped beneath the glacier for millions of years, creating a unique, isolated ecosystem. Blood Falls remains one of the most mysterious and visually dramatic natural phenomena on Earth.

Passage 2: Sailing Stones

In California's Death Valley, rocks appear to move across the flat desert ground without human or animal assistance. Known as the Sailing Stones, their motion puzzled scientists for decades. Recent studies revealed that thin ice sheets, forming during winter nights, allow stones to slide slowly as they are pushed by light winds. This phenomenon demonstrates how seemingly impossible natural events can have subtle and intricate explanations.

Passage 3: Catatumbo Lightning

The Catatumbo Lightning occurs over the mouth of the Catatumbo River in Venezuela, where lightning storms happen almost every night. Strong winds, humidity, and heat from nearby marshes combine to create this spectacular display. The phenomenon can last up to 10 hours a night and occurs for nearly 260 nights a year. It is so intense that the storms are visible from space, making Catatumbo Lightning one of the most extraordinary weather events worldwide.
