What are the most rapidly changing natural landmarks?

 Niagara Falls has been changing very rapidly.

If you look at timestamps just over the past 500 years, you can see the movement.

Notice in the lines above, that it didn’t always have its famous horseshoe shape. That happened due to the lower density on the outer layers of the rock.

The overall recession is because of obvious reasons, water wearing away on the ledges of the falls. But also because of constant weather changes in that region that accelerate that erosion.

In the past 10,000 years, the base of the waterfall has moved more than 7 miles. That might seem like a really long distance, given how small the change is in the above picture—the reason is due to the limestone rock which the waterfall has now reached.

Prior to reaching this stone, and after it—the waterfall will recede much faster than it is now as it gets to the softer ground to erode. (Source: Rate Of Erosion Of Niagara Falls. Marriott on the falls)

In any event, if you ever get the chance, you should surely visit the falls.

What are some of the best rare natural phenomena that occur on Earth?

 

One of the world's most spectacular mass migrations takes place every year at the Gahirmatha Beach in Odisha. Every year starting in November, there is huge migration of Olive Ridley Sea turtles to this beach, for mating and nesting, where they lay their eggs. This is the only beach in India, where this occurs, and it is estimated that the nesting figure, could be as large as 500,00 though of late, there has been a decline due to rampant poaching, and attacks from predators like dogs, sea gulls. The turtles travel all the way from Sri Lankan coast to the beach, where they indulge in mass mating and courtship, after which the eggs are laid. Holes are dug in the sand, by the turtles themselves using their flippers, to a depth of 45 cm and lay between 100-180 eggs at a time. After 50-60 days, the eggs are hatched, and the hatchlings make it back to sea, one of the most spectacular sights, watching the tiny ones reaching the sea en masse. It is also the time, when predators, attack the tiny hatchlings, and it's estimated only 1 in a 1000 survives.

Chandipur

Another unique natural phenomena, at the Chandipur Beach, when the sea tide recedes during low tide, about 1 to 4 km. You can literally walk into the sea during that time.

Loktak Lake

Loktak Lake in Manipur, is noted for it's phumdis or floating islands, which are basically masses of vegetation and soil. The largest of these Phumdis in South East of lake, makes up the famed Keibul Lamjao National Park, the world's only floating park.

What was the greatest natural disaster ever recorded in human history?

 The 1883 eruption of the Krakatoa

volcano

.

It is the most terrifying natural event ever: the volcanic eruption of Krakatoa ( Indonesia ) had a power of 200 megatons , 21 cubic km of incandescent material were expelled and the glow, sound and effects of the explosion were detectable as far away as South Africa and Australia .

The enormous explosion had a shock force equal to 4 times that of the ' Tsar Bomba ' (the most powerful war device ever created by man ), which caused an impressive number of victims: 36,000, equal to approximately 165 human villages completely wiped off the face of the Earth.

The bluish reflection present today on the visible face of the Moon

is due precisely to the abnormal release of ash caused by the explosion.

What are some unusual natural phenomena that can be observed on Earth?

 Everyone dies, but it's such a rare event that it only happens once in a lifetime to anyone or anything. I think death is the rarest phenomenon that can ever occur to any being.

In the case of humans, death is extremely rare, and once it occurs, we are wiped off the face of the Earth, but I think we are simply transforming into some other kind of energy.

In nature, there are phenomena that restore what has been destroyed.

The same thing happens to us. We don't die; we simply change to adapt. Nature wastes nothing, not even waste.

I believe death is one of the greatest phenomena that occur in nature.

What lessons can we learn from natural reactors like Oklo to make human-made reactors safer?

 The most successful nuclear reactor in history ran for 300,000 years without a single human engineer—and never melted down. Discovered in 1972 in the Oklo region of Gabon, Africa, this ancient geological anomaly provides a spectacular masterclass in passive safety and nuclear waste containment.

During the Proterozoic eon, the natural concentration of the fissile isotope uranium-235 was around 3 percent—virtually identical to the enriched fuel used in many modern commercial reactors. When groundwater seeped into these rich uranium deposits, it acted as a neutron moderator. The water slowed down fast-moving neutrons, allowing them to split other uranium atoms and sustain a localized fission chain reaction.

The first major engineering principle demonstrated by Oklo is self-regulation. When the nuclear reaction generated too much heat, the groundwater boiled away. Without liquid water to moderate the neutrons, the fission process immediately halted. As the rock cooled, groundwater eventually seeped back in, and the reactor restarted. This cycle pulsed continuously for an estimated 300,000 years without ever causing a catastrophic meltdown. Modern nuclear engineers apply this exact principle, known as a negative void coefficient, to design passive safety systems. If a modern reactor using this design loses its coolant, the physics of the core naturally force the reaction to shut down, requiring no human intervention or active mechanical pumps.

The second, and perhaps most profound, lesson from Oklo relates to the long-term storage of nuclear waste. A major concern with human-made reactors is how to handle radioactive byproducts like plutonium, cesium, and strontium over geological timescales. At Oklo, these fission products were generated in massive quantities. Yet, modern geological surveys reveal that over the last two billion years, these highly radioactive elements barely moved from where they were created. They remained permanently locked inside the crystalline structure of the uraninite ore and the surrounding clay.

This ancient African reactor provides naturally occurring, empirical proof that deep geological repositories can safely contain high-level nuclear waste. It demonstrates that with the right combination of stable rock and natural clay buffers, radioactive byproducts can be securely isolated from the biosphere for billions of years, even in the presence of flowing groundwater. Ultimately, Oklo proves that the safety mechanisms modern engineers strive to perfect have already been successfully beta-tested by the Earth itself.

Why is Iran a relatively small exporter of natural gas compared to Qatar despite having similar reserves?

 Beneath the Persian Gulf, Iran and Qatar share the largest natural gas field on Earth. Yet one became a global export powerhouse, while the other barely sells a drop abroad.

The divergence comes down to a mix of demographics, geopolitics, and infrastructure. Several major factors keep Iranian natural gas largely at home:

• Massive Domestic Consumption: Qatar has a population of around 3 million people, meaning almost all the gas it pulls from the ground can be sold abroad. Iran, by contrast, is a sprawling nation of over 85 million residents. The vast majority of Iranian natural gas never leaves its borders. It is heavily subsidized and used to heat homes, power electricity grids, and fuel a large domestic petrochemical industry. Additionally, Iran must reinject huge volumes of natural gas into its aging oil fields to maintain well pressure and keep its lucrative crude oil flowing.
• The Sanctions Barrier: Exporting natural gas on a global scale requires chilling it to -260°F (-162°C) to create Liquefied Natural Gas (LNG), a process that requires massive capital and highly specialized technology. In the 1990s and 2000s, Qatar partnered with major international energy firms to build state-of-the-art LNG terminals. Iran, however, has faced decades of stringent international sanctions. These financial and technological embargoes effectively locked Iran out of the LNG revolution by barring Western companies from providing the necessary liquefaction technology or the billions in required foreign investment.
• Pipeline Reliance: Because Iran lacked access to the LNG technology needed to load gas onto ocean-crossing ships, its export strategy has relied almost entirely on regional pipelines. Building pipelines is geographically restrictive, expensive, and politically complex. While Iran manages to export some gas to neighboring countries like Turkey and Iraq, these pipeline volumes represent a mere fraction of what Qatar's fleet of massive LNG carriers transports to buyers in Asia and Europe.

Ultimately, while the two nations sit on the exact same gas field, Qatar was free to build a global export machine, while Iran was forced to use its share to sustain its own massive and heavily isolated domestic economy.

Is Angelina Jolie's beauty natural or plastic surgery?

 It looks natural but it's the most successful surgeries that have been performed. If a plastic surgery gets successfull it turns out to be like this. Angelina Jolie is seen as almost a perfect women ever existed. But it comes with a cost. It's very normal for the entertainment industry to go under the knife and project your perfect self. So did Angelina Jolie

You can clearly see the difference here. She had gone under rhinoplasty for a more slimmer nose and a brow lift and a face lift which made her jaw so chiseled and sharp. Her hairline has been fixed and made it look more round and feminine. Her eyes shaped have changed it's shape too.

And you can view in this photo that she has performed some lip fillers on her upper lips to make it more larger to complement the lower lips which changed the way her lips moved while talking which I personally found attractive. And her natural eyes are dark green but she wears contacts to enhance their colour.

She previously had natural blonde hair but she chose to dye her hair darker to complement her appearance and to let her eyes stand out .

In conclusion, even the world's prettiest woman has multiple surgeries to be more prettier and to fit in these societal standards. If a surgery turns out a success then the perfect example is of Angelina Jolie. 

What is an impressive natural phenomenon that very few people know about?

 The passage of these giants in the middle of the coasts of the North Sea.

In the photo a mammoth iceberg almost 50 meters high passing near the Canadian village of Ferryland (province of Newfoundland and Labrador). That area of ​​the Atlantic Ocean is known as Iceberg Alley , precisely because of the passage of these beasts .

About 600 km off Ferryland , one of them struck and sank a famous ocean liner on its maiden voyage on 15 April 1912. The name need not be specified.
