While billions of stars are scattered throughout the universe the one at the center of our solar system plays a special role for us here on earth our Sun formed about 4.5 billion years ago in the Milky Way galaxy's Orion's fur It was born when a cloud of dust and gas known as a solar nebula Collapsed and in the middle of this formation matter condensed into a burning ball of gas that became our Sun The sun's fiery nature along with a tremendous gravitational pull and an extensive magnetic field Helped it to become the heart of our solar system. The Sun can be divided into six layers or regions the corona the chromosphere the photosphere the convective and radiative zones and the core in terms of atom count the Sun is about 91% hydrogen the sun's fuel eight point nine percent helium and point one percent heavier elements such as carbon and nitrogen Due to the sun's extreme temperatures these elements stay in a gas-like phase called plasma In the core temperatures r...

Top 10 Awesome Things You Didn't Know AboutAnts 10. They Can Stitch Up Wounds Minor wounds are considered just an annoyance, with advanced medicine just a call away. However, if we are in the middle of the African Savannah, with no first aid kit, and the nearest help we can get is still days away, fixing that little wound can mean life or death. Some tribes, like the Masai Tribe in EastAfrica, faced the same problem and found an easy first aid trick on the go -- the army ants strong pincers. If a Masai warrior is out in the African bush and suffers a wound that needs stitching, all he needs to do is look for an Army Ant'snest and pick a few of the biggest ants he could find and have them bite both sides of the wound then break off the body, leaving just the head. The seal created by the makeshift surgical staples can last for days and can be easily replaced if needed. 9. Before God Created Man, He Created AntsFirst We all know that we, as a species, are relat...

  Image of Do-do bird.  If there's one thing most people know about the dodo bird, it's that they were dumb. If they had been human, they would have been the kind of person who changes pants while driving. Yes, legend has it, this creature was only really ever a danger to itself, a true poster child for The Darwin Awards...at least, that's the story we've been fed. But is it true? Turns out, the whole story that the dumb dodo got itself hunted to extinction by being so stupid may have been a big load of doo-doo.  Leon Claessens, Professor of Vertebrate Paleontology and Evolution at the Netherlands' Maastricht University, believes the Dutch sailors who first encountered the bird in 1598 didn't hunt the birds to extinction, though the sailors likely had an indirect role in the demise of the species. Previously, it was believed the birds were fat and were hunted for food. But in the dense jungles of their native Mauritius, the bird would have been much leaner than ...

  Image of a Dinosours (T-Rex)  Probably noother creatures on the planet have struck as much fearand awe in our hearts as the dinosaurs. (roaring) The earliest dinosaurs appeared about 245 million years ago during the Triassic Period. When most of the Earth'slandmasses were still joined together as the super continent Pangaea. Over millions of years Pangaea split apart causing the dinosaurs to become separated for the very first time. This led the reptiles to adapt to their specific habitats and diversify. Giving rise to many new dinosaur species. According to some estimates, more than 1,000 species of dinosaurs have roamed the Earth.  All dinosaurs descended from reptiles called Archosaurs. From there dinosaurs branched out into two major groups, Saurischia and Ornithischia based on the shape and orientation of their pelvis. In Saurischian dinosaurs, such as TyrannosaurusRex and Brachiosaurus, the pelvis' pubis bone faces forward and down. In Ornithischian dinosaurs, suc...

With the development of four-stroke internal combustion engine petrol became essential to auto motive industry today almost all petrol is used to fuel automobiles with a very small percentage used to power agriculture equipments and aircraft welcome to gnp animations in this video we are going to see how petrol is made the petrol also known as gasoline is avolatile flammable liquid obtained from refinement of petroleum orcrude oil found deep within the earth the crude oil itself derived from decayed organisms that were buried along with the sediments of early geological erasover tens of millions of years this organic residue called kerogen was converted to crude oil by a pair of complex chemical processes known as diagenesis and catagenesis the combination of these complex.Reactions creates a hydrocarbon mixture known as petroleum or crude oil there are many steps involved in manufacturing of petrol but in this video we are simply going to see 4 steps step 1 collecting th...

  Image of Giant Sequoia Tree. Giant sequoias are rare trees. Giant sequoias can only grow along a narrow, 260 mile strip on the western slope of the Sierra Nevada mountains-between 5,000 and 7,000 feet. Giant sequoia trees are among the oldest trees in the world. A Giant Sequoia tree can live up to 3,000+ years. Thank you for visiting my site.

Titanium Tungsten   In terms of tensile strength, tungsten is the strongest out of any natural metal,142,000 psi. But in terms of impact strength, tungsten is weak, it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi. But when you figure in titanium’s density and make a pound-for-pound comparison, it beats tungsten. Looking at titanium in terms of compression strength, it scores much lower on the Mohs scale of hardness.  Thank you for visiting my site.

  Hydrangeas are a genus of over 75 species and 600 named cultivars that are native to a wide range of regions and countries, including Japan, Asia, Indonesia, Himalayan mountains, and the Americas. Another common name for hydrangea is hortensia. Hydrangeas can grow as climbing vines and trees, but are most commonly grown as a shrub. The plants can grow from 1 foot tall, all the way to close to 100 feet tall as a climbing vine. The beautiful flowers produced by this plant is what makes these so popular. Most put on a showy display from early spring all the way into fall. The large flowers come in a variety of shapes, colors, and sizes. Hydrangea blooms can be pink, blue, red, white, purple and green! The flowering shrubs can grow in partial shade to full sun. Many people remember hydrangea shrubs from their childhood. Today we are falling in love with them all over again. And the good news is that we can now grow many hydrangea varieties our grandmothers never even dreamed of. Some...
