  45. 45. Meteors (Shooting Stars) Kollace Education Rennaisance www.kollace.com
  46. 46. Meteors (Shooting Stars) These are pieces of rocks floating in space, which sometimes enter the earth’s atmosphere Kollace Education Rennaisance www.kollace.com
  47. 47. Meteors (Shooting Stars) They experience a force of friction of air and start burning. They appear as a ball of fire falling towards earth emitting intense light. They are also known as Shooting Stars but they are not actually Stars or in anyway connected to them. Most of them get completely burnt in the atmosphere. Kollace Education Rennaisance www.kollace.com
  48. 48. Meteorites Kollace Education Rennaisance www.kollace.com
  49. 49. Meteorites Some meteors are so large and do not get completely burnt. So they reach earth and are known as Meteorites. Kollace Education Rennaisance www.kollace.com
  50. 50. Comets These are heavenly bodies which revolve around the sun in highly elliptical paths. They appear in the sky as a ball of fire with a TAIL. The tail always pointing away from the Sun. e.g. HALLEY’S COMET Kollace Education Rennaisance www.kollace.com
  51. 51. Comets Why do they have tail??? They are composed of rocks like material surrounded by large masses of easily vaporised substance like water, ammonia, methane etc. When these approach Sun, some of its material gets vaporised due to heat of the Sun. Light of the Sun exerts pressure on these vapours and forces them away from the comet in form of a tail. Kollace Education Rennaisance www.kollace.com
  52. 52. Comets Halley’s Comet It has a time period of 76 years. Last seen in 1986 and will now be visible in 2062. Kollace Education Rennaisance www.kollace.com
  53. 53. Structure of Earth The Earth can be broadly divided into Three different Layers. Crust Mantle Outer Core Inner Core Kollace Education Rennaisance www.kollace.com
  54. 54. Structure of the earth Earth is composed of a number of layers. Though we have not been able to dig more than 10 Km into the earth’s crust but we have studied it in details from the study of Seismic Waves. Seismic waves are produced during Earthquakes. But in addition to natural seismic waves we can also produce artificial waves by Underground Nuclear Tests. Velocity of seismic waves depends on composition of region from which they pass. From the study of their velocities we can collect more information and a picture of earth’s interior. Three layers of earth are: Kollace Education Rennaisance www.kollace.com
  55. 55. The three layers… Crust: a. Top 30-40 Km layer of earth. b. Contains mainly rocks of silicates (Containing SiO2). c. Its thickness is lesser under sea floor. Mantle: a. From 40 km – 3000 Km. b. Rich in Iron and Magnesium Silicates. c. Not under direct observation. Core: a. Innermost layer beyond 3000 Km. b. It consists mainly of Pure Iron alloyed with some Nickel. c. Its material is in FLUID state. Kollace Education Rennaisance www.kollace.com
