Albert Einstein's quote, "Look deep into nature, and then you will understand everything better", reminds us that nature is humanity's primary source of learning. Nature guides us to understand ourselves, our world, and the universe; revealing our humble position and the magnificent power of the Creator.
Let us commence with exploring one of the most fascinating and mysterious natural phenomena found in Antarctica. This is the southernmost continent; the last discovered landmass (in the 18th century) and the coldest place on Earth. Winter temperatures can drop below -60°C, rendering it uninhabitable, except for research stations housing a maximum of 5,000 people in extreme conditions. The presence of wildlife is extremely limited, consisting of algae and bacteria, and a few living organisms, such as mites, worms, penguins, seals, and polar bears. Vegetation is equally sparse, represented by short-lived tundra plants, which adapt to the harsh climate.
Amidst this harsh environment, Blood Falls flow! Yes, dear reader, you read correctly; they are blood-like ruby-red waterfalls caused by dissolved iron oxide.
In eastern Antarctica, along the banks of the Taylor Glacier, lie the Blood Falls, which were discovered in 1911 by the geologist Thomas Griffith Taylor, whose name the glacier bears. The red color of the waterfalls results from iron oxide, formed by oxidation reactions between diverse elements in the region's highly saline waters. These elements had been stored and isolated for millions of years in airless and light-less pockets. Scientists in this region are still diligently studying the reasons for the formation and subsequent flow of these elements. A process turns ice into a flowing, ruby-red liquid amidst the thick white snow, creating a unique scene that evokes awe, admiration, and wonder.
If we leave Earth's surface and descend to its deepest oceans, we will encounter the Pacific Ocean that spans the length and breadth of the planet. Its immense size contributes the majority of our planet's captivating blue color, which dazzles astronauts and graces satellite images. In the heart of this vast ocean, towards its shores in the Far East, lies the deepest point on Earth, the Mariana Trench.
It is approximately 2,542 km long and 69 km wide at its widest point. It is crescent-shaped and its deepest point reaches more than 11 km below sea level. This immense depth surpasses the height of Earth's tallest peak, Mount Everest, which is approximately 8,850 meters tall.
The Trench's name comes from the neighboring Mariana Islands, which were a Spanish colony; they were named in honor of Mariana of Austria, the widow of King Philip IV of Spain. The entire zone is currently a natural reserve under the jurisdiction of the United States of America. Numerous scientific expeditions striving to explore the profound depths of the trench have revealed a thriving and astonishing life. Marine creatures there have adapted to the immense sea pressure, which exceeds the pressure at sea level by a thousandfold.
Due to the extreme scarcity of food, resulting from the trench's immense distance from the surface and the rare occurrence of terrestrial plants, scientists have discovered that the microbial masses there feed on hydrogen and methane released by chemical reactions between seawater and rocks. As for the other creatures, they devour marine organisms lower than them in the food chain.
With its immense depths, unique life forms, and harsh environment, the Mariana Trench continues to hold some of Earth's deepest natural mysteries, a testament to the wonders of God's creations.
