How Greenland got its name when it is not really green?
Greenland was named by a Viking named Erik the Red (an Icelandic murderer who was exiled to the island).
Historians believe Erik chose the name Greenland as a marketing strategy: in hopes that the name would attract settlers. The word โgreenโ promised Nordic people they would find lush, green fields waiting for them in the new region.
As Erikโs ship could land on the southwestern corner of Greenland, it is possible that he discovered a more appealing section of the country and chose the name before he realized how much ice he was dealing with.
But according to scientists, Greenland was actually quite green more than 2.5 million years ago. Biologists say Greenland may have been home to similar forests we see throughout northern part of America, Europe and Asia today.
Although now more than 80% of Greenland is covered in ice, some experts believe it may soon be green again, if the sheets of ice melt due to climate change.

What are three largest islands on Earth? ๐ฅGreenland is the largest island in the world. With a total covered area of 2,130,800 sq km (822,700 sq miles), it is located between the Atlantic and the Arctic Ocean. Greenland has the population of about 55,000โฆ
What are the second name of Borneo and some other of its unique marks?
Although the name Borneo is more commonly known worldwide (it may derive from the Sanskrit word vรกruแนa meaning either โwaterโ or Varuna, the Hindu god of rain), on some maps the island can be found under the name of Kalimantan.
Kalimantan is the Indonesian name and in Indonesia this word refers to the whole island.
Some countries use โKalimantanโ to indicate the Indonesian portion of the island (73% of its area).
The word Kalimantan or Klemantan was derived from the Sanskrit word Kalamanthana, meaning "burning weather" possibly to describe its hot and humid tropical weather.
โ๏ธItโs the only Island in the world that is divided between three countries: Indonesia๐ฎ๐ฉ, Brunei ๐ง๐ณ and Malaysia ๐ฒ๐พ.

What are the largest living birds?
โ The largest living bird in both size and weight is the ostrich. These giants from Africa grow up to 2.7 meters (9 ft) tall and can weigh up to 130 kilograms (287 lb).
โ Found in the Andes mountains in South America, the Andean condor (Vultur gryphus) is the largest flying bird in the world by combined measurement of weight and wingspan. It has a maximum wingspan of 3.3 m (10 ft 10 in) and weight of 15 kg (33 lb).
โ In terms of wingspan, the record holder among flying birds is the wandering albatross (Diomedea exulans) with a wingspan of 3.4 meter (11-foot). It uses those massive flappers to travel hundreds of kilometers in a single journey.
โ The emperor penguin (Aptenodytes forsteri) from Antarctica is the tallest and heaviest of all living penguin species that cannot run or fly but are excellent swimmers. The male and female are similar in plumage and size, reaching 100 cm (39 in) in length and weighing from 22 to 45 kg (49 to 99 lb).

Can the largest living flying birds carry a human?
๐ฆ Although in some books or movies one can find stories about a big flying bird picking up a human, such a scene has nothing to do with the reality.
๐ฆ Neither condors nor other big eagles cannot in fact lift an adult person or even a child.
๐ฆ As a rough estimate by scientists, a bird of prey can carry half its body weight.
๐ฆ An Andean condor weighing up to 15 kilos can in theory carry an object that weights no more than 7,5 kilos, or even less.
๐ฆ Eagles with the greatest weight-carrying capacity are the bald eagle, the Philippines eagle, the harpy eagle, and the crowned eagle.
๐ฆ The heaviest recorded weight a bird can lift is 6,8 kg (15 lb), held by the bald eagle for lifting a mule deer fawn of the said weight.
๐ฆ In theory, it would take ten bald eagles to lift an adult human that weighs about 70 kg.

What is the most powerful bird of prey?
Although the harpy eagle only weighs between 6 and 9 kg (13 to 20 lb), it is considered the worldโs most powerful bird of prey.๐ช
In terms of body length, the harpy eagle measures about 1 meter (up to 42 inches) and has a wingspan of about 2 meters (up to 88 inches).
The harpy eagleโs legs and talons are the thickest and largest of any bird of prey.
This extraordinary physical characteristic means that it wonโt settle for small animals. Instead, it focuses more on mammals like sloths ๐ฆฅ and monkeys ๐.
With its deadly talons, the harpy eagle can carry prey as heavy as its weight.
Smaller males have mostly been recorded to carry about half their weight or medium-sized prey.
But an adult female harpy, which is almost twice bigger then males, can snatch animal like sloths and monkeys weighing 5-9 kg from trees and continue its flight without landing.

What is chemistry?
๐งชChemistry is the study of matter, defined as anything that has mass and takes up space, and the changes that matter can undergo when it is subject to different environments and conditions.
๐งชChemistry seeks to understand not only the properties of matter, like the mass or composition of a chemical element, but also how and why matter undergoes certain changes โ whether something transformed because it combined with another substance, froze because it was left for two weeks in a freezer, or changed colors because it was exposed to too much sunlight.
๐งชThe reason why chemistry has to do with everything we do is that almost everything in existence can be broken down into chemical building blocks.

What are the main building blocks in chemistry?
These are the chemical elements - substances made of a single atom.
Each chemical is unique, composed of a set number of protons, neutrons and electrons, and is identified by a name and a chemical symbol, such as "C" for carbon.
The elements that scientists have discovered so far are listed in the periodic table of elements, and include both elements that are found in nature like carbon, hydrogen and oxygen, as well as those that are manmade, like Lawrencium.
Chemical elements can bond together to form chemical compounds, which are substances made up of multiple elements, like carbon dioxide (CO2 - one carbon atom connected to two oxygen atoms), or multiple atoms of a single element, like oxygen gas (O2 - two oxygen atoms connected together). These chemical compounds can then bond with other compounds or elements to form countless other substances and materials.

Experts often divide chemistry into 5๏ธโฃ main branches.
Analytical chemistry involves the analysis of chemicals, and includes qualitative methods like looking at color changes, as well as quantitative methods like examining the exact wavelength(s) of light that a chemical absorbed to result in that color change.
Biochemistry uses chemistry techniques to understand how biological systems work at a chemical level.
Inorganic chemistry studies the chemical compounds in inorganic, or non-living things such as minerals and metals.
Organic chemistry deals with chemical compounds that contain carbon, an element considered essential to life.
Physical chemistry uses concepts from physics to understand how chemistry works. For example, figuring out how atoms move and interact with each other, or why some liquids, including water, turn into vapor at high temperatures.

What is the other name of the periodic table of elements?
It is also called Mendeleevโs periodic table after the name of a prolific Russian chemist Dmitri Mendeleev (1834-1907)โฌ๏ธ.
In 1869 Mendeleev published an article, in which presented his first version of a table containing then known elements arranged in order of relative atomic mass.
He also noticed that there were plenty of gaps in the table and exceptions to the emerging patterns, and predicted that there were elements that existed but simply hadnโt yet been discovered.
Confirmed in later years, those predictions made Mendeleevโs theory even more valuable.
For example, when the element that should fit below aluminum in his table was discovered in 1875 and called gallium, its properties were found to be very close to Mendeleev's calculations.
Important scientific contributions that helped Mendeleev were also made by Antoine-Laurent de Lavoisier, Johann Wolfgang Dรถbereiner, John Newlands, Julius Lothar Meyer.

Who manages the periodic table and what are its newest elements?
Today, the periodic table is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack), responsible for deciding what needs to be changed based on specially created critera.
The last four elements to be discovered were officially recognized by the IUPAC in January, 2016: they are nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og), with atomic numbers 113, 115, 117, and 118, respectively.
โน๏ธ Looking back in history, itโs worthy to note that ancient people knew about 10 elements: carbon, copper, gold, iron, lead, mercury, silver, sulfur, tin, and zinc.
Arsenic, antimony, and bismuth were discovered prior to 1500 AD, while phosphorus, cobalt, and platinum were discovered by 1750.
Most natural elements were found by 1900.
Technetium became the first synthetic element in 1937.
The first transuranium element to be discovered (neptunium) was found in 1940.
