Top 5 Amazing World Facts The world


is full of surprising and largely unknown facts. There are approximately 200 countries, billions of people, a wide range of species of plants and animals, and nature's secrets, all of which are full of fun, fascinating, and interesting facts. The following is a list of the top ten amazing facts about the world, which you should check out if you enjoy discovering new information about the world.

1. Fastest Gust Of Wind In Australia, an island known as Barrow Island was struck by Olivia, a tropical cyclone. This tropical cyclone was so powerful that it broke the 1934 New Hampshire wind record of 231 miles per hour to become the world's fastest gust of wind, reaching 353 miles per hour.

2. Best Place to See Rainbows Who doesn't love to look at a rainbow and admire the beauty of nature? Hawaii is the best place in the world to see rainbows. The American Meteorological Society says that Hawaii will be the most beautiful rainbow sighting in 2021. Because of the mountains, rain, pollen, pollution, and a lot of cresting waves, this place has the best rainbows, both in terms of quantity and quality.

3. Flowers are changing colors, but it doesn't just happen overnight. However, a recent 2020 study by Clemson University scientists has demonstrated that this phenomenon, which we cannot see with our eyes, is caused by global warming. The amount of ultraviolet radiation reaching Earth has increased as a result of the ozone layer's depletion. The UV pigmentation of flowers has increased as a result of increased UV radiation, which has deteriorated their pollen and posed challenges for pollinators like bees.

4. This may seem odd to you, but it is a fact: whale song maps the floor of the ocean. In an effort to mate with a female, male Fin whales sing incessantly. Scientific American claims that it is the most audible song ever recorded by any marine life and can be heard up to 1000 kilometers away. Due to its depth of 2.5 kilometers, it can be used to sonically map the ocean floor. Scientists can get precise measurements from this sound's reverberation. Compared to air guns, which are the most common tool used by researchers, it is more natural for sea life.

5. Plants That Fossilized on Green Land Although an ice sheet covers most of Greenland, this wasn't always the case. Britannica claims that Greenland may be the only and largest remnant of the Northern Hemisphere's Pleistocene glaciation. Scientists have discovered fossilized plants and well-reserved biomolecules under the ice sheet, about 1.4 kilometers from the core. This indicates that once the vast ice sheet melted, it became green and reformed into the ice we see today.

4 Fun Facts About Antarctica - 2022


1. Antarctica holds most of the world’s fresh water

An incredible 60-90% of the world’s fresh water is locked in Antarctica’s vast ice sheet. The Antarctic ice sheet is the largest on Earth, covering an incredible 14 million km² (5.4 million square miles) of Antarctic mountain ranges, valleys and plateaus. This leaves only 1% of Antarctica permanently ice-free. Some areas are ice-free in the summer, including many of the areas we visit on the Antarctic Peninsula.

At its deepest, Antarctica’s ice is 4.5km (2.7 miles) thick – that’s half the height of Mt Everest! If it all melted, global sea levels would rise about 60 m (200 ft).

2. Antarctica is a desert

With all of that fresh water held in the ice sheet, how could Antarctica be a desert?

When most of us think of deserts we think of sand dunes and sizzling temperatures, but technically a desert doesn’t have to be hot or sandy, it’s more about how much precipitation the area receives as rain, snow, mist or fog. A desert is any region that receives very little annual precipitation.

The average annual rainfall at the South Pole over the past 30 years was just over 10 mm (0.4 in). Although there is more precipitation towards the coast, the average across the continent is low enough to classify Antarctica as a polar desert.

So while Antarctica may be covered in ice, it has taken an incredible 45 million years to grow to its current thickness, because so little rain falls there.

As well as being one of the driest continents on Earth, Antarctica is also the coldest, windiest and highest.

3. Antarctica used to be as warm as Melbourne

Given that the coldest ever land temperature was recorded in Antarctica of -89.2°C (-128.6°F), it can be hard to imagine Antarctica as a warm, temperate paradise. But Antarctica hasn’t always been an icy land locked in the grip of a massive ice sheet. In fact, Antarctica was once almost as warm as Melbourne is today.

Researchers have estimated that 40-50 million years ago, temperatures across Antarctica reached up to 17°C (62.6°F). Scientists have also found fossils showing that Antarctica was once covered with verdant green forests and inhabited by dinosaurs!

4. The Antarctic Peninsula is one of the most rapidly warming areas on Earth

The Antarctic Peninsula is warming more quickly than many other areas on Earth. In fact, it is one of the most rapidly warming areas on the planet. Over the past 50 years, average temperatures across the Antarctic Peninsula have increased by 3°C (37.4°F), five times the average increase on Earth.

This has led to some changes, for example where and when penguins form colonies and sea ice forms. It also means that the lush mosses of the Antarctic Peninsula have a slightly longer growing season.
