Earth is the planet where we live. But most of things about earth, we don't know. So, here we will talk about it. On other hand we will also talk about some type disease that was unknown from us till yet.

There is a lot disease that is unknown for us, only doctors know these type of disease, So we thought that we should share this information. So, Read Carefully.

Some Facts About Earth

1. To put the size of each of these bodies in perspective, think of the Earth's moon as a tennis ball and Earth as the size as a basketball. The sun's diameter is about 109 times greater than Earth's, whereas Earth is just about four times larger in diameter than the moon.

2. Orbiting debris smashed into the newly formed Earth, and gravity and radioactive processes heated its interior to nearly 2000 degrees Fahrenheit. A solid inner core formed as iron and nickel were absorbed into the center. This inner core was surrounded by a molten outer core, and then less dense silicates formed the mantle and crust.

3. The Earth had the energy to release trapped water from the energy supplied by the collisions that had delivered the minerals in the first place.

4. More than 80% of the Earth's surface is volcanic.

5. The word "planet" comes from the Greek word planetai for "wanderer.'

6. The great impacts that gave Earth its mass had the potential to blow away the fragile atmosphere that was forming and turn the oceans into steam. Despite these threats, Earth went through a normal birthing process for a habitable planet.

7. Strong evidence suggests that the universe began with the Big Bang about 13 billion years ago, and two thirds of its history passed before our own solar system was formed. During this time, stars evolved and died, supplementing the basic hydrogen, helium, and trace of lithium that the universe began with and providing more complex atoms such as carbon, oxygen, silicon, magnesium, and nitrogen. The way Earth was formed allows for its many unique traits that have developed and will develop during its life.

8. The birth of Earth's moon is singularly important because it stabilizes Earth's tilt. Without the moon, Earth would still have wild changes in climate and be uninhabitable. The stabilizing tug of the moon tempers Earth, resulting in the minor tip that causes summer and winter seasons.

9. Earth is made up of hydrogen gas, stardust, and gravity. The gas and dust floating in space were drawn together by gravity and they formed into a spinning disc. As this disc collided with and absorbed rock bodies, the Earth formed. Astronomers believe the formation of Earth was relatively quick.

10. Earth is called a terrestrial planet because it is made almost entirely of rock and metal. Because Earth formed inside the snow line-meaning it was close enough to the sun that water, carbon, and nitrogen were all in a gaseous state-the elements so essential to supporting life had to be supplied in some other way. They were carried to the Earth by dirty snowballs-asteroids that retained water in hydrated minerals. Later those hydrated minerals were heated and the trapped water was released.

11. Earth's Amazon rainforest is home to one third of the planet's land species, illustrating Earth's ability to sustain itself within a concentrated area.

12. The Earth's plates move just a few inches a year-about as fast as a person's fingernails grow. This continental pattern predicts that 250 million years from now, a new supercontinent will be born.

13. The metaphor of rock being like Earth's blood works because Earth's levels of air and water are kept in balance by rock's continuous circulation.

14. Pangaea was not the beginning position of the land on Earth, but one of as many as six lost worlds that have come and gone. Pangea was preceded by Pannotia about 550-650 million years ago and by Rhodinia around 1.8 billion years ago. Before them, at intervals of roughly 500 million years, Nuna, Kenorland, and Ur existed and then broke up.

15. Earthquakes, volcanoes, and mountains are all formed by Earth's moving plates.

16. Researchers in the the field of astrobiology have found that Earth's current conditions are temporary and that Earth's stable climate is an anomaly that will end in the next billion years.

17. Because Earth was hit by huge, hurtling chunks of rock and ice, they cratered so deeply into the interior of the planet that their heat, water, and future atmospheric gases were anchored there and retained by gravity. Earth's ocean of magma was created by bodies crashing into the planet a bit later in its development.

18. As the earth cooled after it had finished growing, the lithosphere-the hard, outermost layer between the mantle and the Earth's crust-cracked like an eggshell and split into seven large and twelve small floating islands with jagged edges. These islands are the tectonic plates that move continuously over the viscous mantle, rubbing, pushing, and trying to mount one over the other.

19. Under the oceans, there are the earth's largest mountain ranges that circle the planet like the stitching on a baseball.

20. The beginning of the Industrial Revolution marked the beginning of humanity's affecting Earth's environment by producing enough carbon dioxide to affect the atmosphere's global balance and chemical composition.

21. Holes drilled as deep as 5 miles into the Earth's reveal that the rock temperature increases about 37 degrees Fahrenheit per 320 feet. Even on the deepest sea floor, rock remains slightly above freezing.

22. Pangea broke up starting along the line that would become the mid-Atlantic ridge when the existing fracture at the southern end of South America/Africa widened and opened the rift like a zipper. As these new continents moved apart, they pushed and folded up the Earth's crust and created great mountain ranges.

23. Earth's unique mix of land and ocean makes the Earth relatively stable by cycling carbon dioxide. Carbon dioxide cycling moderates temperature swings that would otherwise occur.

24. The name "Earth" comes from Old English and Old High Germanic words (eorthe and erda, respectively) for "ground" or "soil," and it is the only name for a planet of the solar system that does not come from Greco-Roman mythology.

25. Earth can be seen as a living, breathing organism: it regulates temperature, burns energy, continually renews its skin, and experiences changes to its face as it ages with time.

26. Within 10 million years of Earth's birth, its average interior temperature was hot enough to melt virtually the entire planet, which caused the core to sink to the middle of the planet and left the mantle a bubbling, viscous layer.

27. The Earth's plates were divided into land masses and oceans because of the difference in the thickness and composition of the planet's two types of crust. Continental crust, mostly composed of relatively lightweight granite, is about 18 to 30 miles thick. The much denser basalt that makes up the oceanic crust is only 5 or 6 miles thick. Because they are more buoyant, the continents "float" higher on the mantle than the ocean floors do.

28. Earth's greatest source of heat, besides the sun, is its interior, which conducts a hundred billion billion calories of energy to the surface each year-or 1.5 microcalories per .155 square inch of the earth's surface each second. So much energy radiates from inside the Earth that it could satisfy all human energy needs three times over.

29. Earth was originally born as a twin to the planet Theia, which was about half as wide as Earth and roughly the size of Mars. The two planets shared an orbit for several million years until they collided. Earth absorbed Theia, and the remaining debris eventually coagulated into Earth's moon. The mass donated by Theia gave Earth the gravity necessary to sustain a substantial atmosphere.

30. The Himalayas are examples of the movement of tectonic plates against each other.

Facts about Disease

31. The National Osteoporosis Foundation estimates that osteoporosis is responsible for more than 2 million fractures each year.

32. As of June 26, 2009, there are 59,814 cases of the H1N1 flu virus with 263 deaths. The mortality rate of of the swine flu is .44% so far.

33. Depressed individuals have two times greater overall mortality risk than the general population due to direct (e.g., suicide) and indirect (medical illness) causes.

34. Nearly half of U.S. youths and adolescents are unaware of their HIV infection, and less than a quarter are tested for the virus.

35. Men have a higher risk of death from diabetes than women.

36. Age is the most significant risk factor of developing heart disease, followed by gender, family history coupled with ethnic background, smoking, obesity, lack of exercise, high blood pressure, diabetes, and high blood cholesterol.

37. HIV is primarily spread through 1.unprotected sex (vaginal, anal, oral) with someone who has HIV, 2.sharing needles or syringes, 3.being born to an infected mother, and 4.blood transfusions.

38. Inhaled insulin is an emerging twenty-first century option for people with Type 1 diabetes. Companies are also working on an insulin tablet that can be given under the tongue.

39. Smoking causes an estimated 90% of lung cancer. Tobacco has killed 50 million people in the last decade. If trends continue, a billion people will die from tobacco use and exposure this century, which equates to one person every six seconds.

40. The ability for the transmission of the HIV virus from animal to human required high-risk transmission channels. Scientists cite the emergence of colonialism and the growth of large colonial African cities. This growth led to a higher degree of sexual promiscuity, the spread of prostitution, and the spread of genital ulcer diseases such as syphilis.

41. Anorexia is the third most common chronic illness in adolescents. Unrealistic Body Expectations.

42. Anorexia has one of the highest mortality rates of any mental illness. Approximately one in 10 cases of anorexia nervosa ends in death.

43. In families with one autistic child, the risk of having a second child with the disorder is approximately 5%, or one in 20. This is greater than the risk for the general population.

44. Types of depression include major depression, dysthymia, adjustment disorders, and bipolar disorders. Within each of these main categories are several subtypes.

45. Depressed people get colds more frequently than non-depressed people.

46. Because osteoporosis has no warning signs, medical experts call it a silent disease. Often the first symptom of osteoporosis is a broken bone from little or no trauma.

47. The source of flu vaccines are chickens and, consequently, vaccines can be dangerous to people who are allergic to eggs. Those people should never receive the injectable or nasal spray vaccine without doctor's approval.

48. Diabetes is the leading cause of kidney failure, accounting for 44% of new cases in 2005.

49. Over 180 million cases of trichomoniasis occur worldwide per year. In the United States, it is estimated that 7.4 million new cases of trichomoniasis occur each year.

50. Today's medical historians have traced the likely beginning of the Spanish flu not to Spain, but to Haskell County, Kansas, where people lived close to their pigs and poultry. When three Haskell County boys were shipped off to Fort Riley, Kansas in late 1917, they carried the virus with them, which spread from U.S. military bases to cities across the country. The virus then spread throughout Europe, brought over with the U.S. troops of WWI, and it returned to the United States in a much deadlier form. Astonished at the rapid and high mortality rate, Americans feared the Germans had put "flu bacteria" in Bayer aspirin or had sneaked the flu through Boston harbor.

51. The earliest description of cancer was found in the Edwin Smith Papyrus dating back to 1600 B.C. It describes what appears to be breast cancer. Though breast cancer was treated by cauterization with a tool called a "fire drill," the author ultimately wrote, "There is no treatment.'

52. On a worldwide basis, depression ranks fourth as a cause of disability and early death according to the Global Burden of Disease Study.

54. The word "diabetes" is Greek for "siphon," which refers to the copious urine of uncontrolled diabetes. "Mellitus" is Latin for "honey" or "sweet," a name added when physicians discovered that the urine from people with diabetes is sweet with glucose.

55. Ancient skeletons and mummies reveal that osteoporosis has existed for thousands of years.

56. Over 300,000 deaths in the U.S. a year are attributed to obesity. Obesity is second only to smoking as a cause of premature death in the United States.

57. The World Health Organization (WHO) reports that diabetes has reached epidemic proportions and expects that 80% of all new cases of diabetes will appear in developing countries by 2025.

58. Insulin in the 1920s was initially extracted from the pancreas of a cow (bovine) or pig (porcine). Today's insulins are created in the lab, cultured from bacteria and yeast through recombinant DNA.

59. The National Osteoporosis Foundation estimates that about 24% of the approximately 300,000 people who fracture a hip each year die within one year. Many others suffer serious depression and withdraw from society because they are so afraid of breaking bones. Hip fractures are one of the most serious consequences of osteoporosis.

60. HIV is an abbreviation for human immunodeficiency virus, which is the virus that causes AIDS (acquired immunodeficiency syndrome).
