NCERT CLASS-6 GEOGRAPHY CHAPTER-6 NOTES

  NCERT CLASS-6 GEOGRAPHY CHAPTER-5 [MAJOR LANDFORMS OF THE EARTH]     Landforms are a result of two processes.        = within the earth continuous movement is taking place. The 1st or the internal process leads to the super lift net and sinking of the earth’s surface at several places. A hill is a land surface that rises higher than the surrounding area.        = generally, a steep hill with an elevation of more than 600m is termed as mountain. The 2nd or the external process is the continuous wearing down and rebuilding of the land surface. The wearing away of the earth’s surface is called erosion. Different landforms depending on elevation and slope- mountains, plateaus and plains. Mountain is any natural elevation of the earth surface.        = may have a small summit and a broad base. In some mountains, there are permanently frozen rivers of ice, called glaciers. Some mountains are under sea. Mountains arra...

NCERT CLASS- 6 GEOGRAPHY CHAPTER-2 NOTES

NCERT CLASS 6 GEOGRAPHY CHAPTER- 2 [GLOBE: LATITUDES AND LONGITUDES]   Earth is slightly flattened at the north and the south poles and bulge in the middle. Globe is a true model of the earth. Earth rotates from west to east. Equator is an imaginary line that divides the earth into two equal parts The northern half of the earth is Northern Hemisphere. The southern half of the earth is Southern Hemisphere. All parallel circles from the equator up to the poles are called parallel of latitudes. Latitudes are measured  in degrees. Equator represents the zero degrees latitude. 90degree north latitude marks the North Pole and 90degree south latitude marks the South Pole. Distance from the equator to either of the poles is one-fourth of a circle round the earth, 1/4th of 360, i.e, 90degree. All parallels north of the equator are called ‘north latitudes’. All parallels south of the equator are called ‘south latitudes’. Four important parallels of latitudes-       ...

NCERT CLASS-6 GEOGRAPHY CHAPTER-3 NOTES

  NCERT CLASS 6 GEOGRAPHY   CHAPTER- 3 [MOTIONS OF THE EARTH]   Two types of motion of earth are: Rotation and Revolution. Rotation is the movement of the earth on its axis. Revolution is the movement of the earth around the sun in a fixed path or orbit. The plane formed by the orbit is known as orbital plane. The circle that divides the day from night on the globe is called the circle of illumination. The period of rotation is known as the earth day. 6 hours saved every year is added to make one day(24 hours) in leap year. Leap year has 366 days. A year is usually divided into summer, winter, spring and autumn seasons. The ancient Indian astronomer Aryabhatta had stated that the earth is round and rotates on its own axis. On 21st June, the northern hemisphere is tilted towards the sun.           = Rays of sun falls directly on the Tropic of Cancer.           = The North Pole is inclined towards the sun and the places beyo...
