Ytterbium can be used to convert invisible infrared light into green or red light, which can be used in anti-forgery security inks and in bank notes. Ytterbium compounds absorb and give out light in the near infrared which can be used for examining biological tissue and solar cells (Stewart). An isotope of ytterbium, ytterbium- 169, is used in the medical field as a radiation source substitute for a portable X-ray machine where electricity is unavailable (Emsley). This isotope is also used as an alternative for Iodine-125 and Palladium-103 in the treatment of prostate cancer and for diagnostics in the gastrointestinal tract
The element in its natural form is a shiny, ductile, malleable, soft and silver element. The element is slow to react with water however it dissolves rapidly in acids. Gadolinium is found in an oxidized form in nature. Gadolinium is mainly found in monazite and bastnasite. The biggest gadolinium reserves are in Cina, USA, Brazil, Sri Lanka, India, and Australia.
The Chicxulub impact, known as the Chicxulub crater, was formed by an asteroid that collided with the Yucatan Peninsula located in Mexico 65.5 million years ago. The asteroid was said to hold the same energy as 100 million atomic bombs which precipitated an incident that destroyed the dinosaurs and nearly all life on Earth, leaving the atmosphere inhabitable for centuries. What is an Asteroid? Asteroids are pieces of rocks that aren't called planets based on the how small they are. The asteroids are orbiting around the sun mainly in what we call the asteroid belt - an area between the orbit of Mars and Jupiter.
The eruption was caused by a magnitude 5.1 earthquake that struck at 8:32. This earthquake triggered the eruption that blew off a whole side of the volcano. The volcano is created by a destructive plate boundary between the Juan de Fuca boundary and the North American plate boundary. This means it belongs to what is commonly known as the ring of fire. (1980 Cataclysmic Eruption) Both of these eruptions are by volcanoes caused by destructive plate boundaries.
Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a "rare earth", it is a fairly common element, no rarer than cobalt, nickel, and copper, and is widely distributed in the Earth's crust. [3] Most of the world's neodymium is mined in China. Neodymium compounds were first commercially used as glass dyes in 1927, and they remain a popular additive in glasses.
Some have even gone so far as to call this the Earth’s Sixth Mass Extinction Event and indicate that the primary cause of this extinction is human overpopulation and overconsumption (Carrington, 2017). Despite what may seem like compelling evidence that we are nearing or have already passed the point of extreme overpopulation, Malthus’s theories still have their critics. A major argument against Malthus’s predictions about population growth is that all predictions regarding the future of the population are made without adequate knowledge of technological and cultural changes to come. As population growth rates have been on the decline over the past years and we have steered far away from predicted widespread famine with the Green Revolution, there is less of a reason to trust the supposed imminence of overpopulation and its grim consequences (Briney,
How did the Earth originate? Was there any supernatural being behind the creation of the Earth? There have been many claims and theories on how the Earth originated such as “The Big Bang Theory” and “The Nebular Theory” meanwhile there were two theories and claims that caused a debate for almost more than a century which is Evolutionism and Creationism. The Theory of Evolution is false because it could not prove any scientific evidence unlike Creationism that base all of it facts on the Bible, that has been proven scientifically and historically accurate. The Evolution Theory is one of them most common ways to contradict Creationism as it tries to prove that the world is over 4.5 billion years, Humans evolved from apes by natural selections,
Another one was the sightings of UFO’s coming out from the ocean, which was explained to have happened, perhaps because the center of the Earth was populated by extraterrestrial beings, who from time to time emerge from the poles in spacecrafts, perhaps because in the 20th century Hohlwelttheorie was linked with the belief of aliens. Moreover, this theory has also been linked with conspiracies such as that the Nazi specially Hitler knew of an entrance to the interior world at the South Pole, and that Hitler and his colleagues and friends fled there at the end of WWII. In that same wavelength the popular science fiction story “A journey to the Centre of the Earth” by French novelist Jules Verne (1828-1905) has given the theory, its most lasting exposition, since the late 19th century, and in which he describes the discovery of a prehistoric world by explorers who go down a volcano only to find out this interior world, that had its own source of light, water, and flourishing
Introduction “Activities such as burning fossil fuels, pollution, habitat destruction and overfishing are profoundly impacting life on Earth” (FOSS Mass Extinctions). I believe nature 's needs are more important than ours. We are the cause of all of the things aforementioned and we will be the cause of the next mass extinction. Hey-y come on Out-t Many real and fictional examples support my claim and have brought me to my conclusion, including a fictitious story called, “Hey-y come on out-t” (written by Shinichi Hoshi in 1989). is a fictional story in which humans find a seemingly bottomless pit.
Was iron formed in the earth ? It is thought that the earth was once a part of the sun and then separated , so scientists thought that iron was formed in the sun but this supposition proved to be wrong because the surface heat temperature of the sun is 6000 Celsius degrees while the temperature of the core ranges from 15 million to 16 millions Celsius and in this degree , though high , is not enough to form an iron atom . The whole temperature of the solar system is not sufficient to produce just on atom from iron . The observable universe is composed of hydrogen (74%) and Helium (24%) ,while the other 105 elements form (2%).On studying the sun ,scientists found that it is only hydrogen and Helium that are there , it is known that hydrogen atoms fuse together to form helium and the sun nuclear reaction will remain as so till the sun runs out of hydrogen then begins to change into red giant where it will swallow the moon and the other planet . The Holy Quran records this cosmic event in its verses before science .
