Transcription

1 15. THE GLOBE AND THE MAP 1 DEFINE THE FOLLOWING 1. AXIS : The imaginary line which passes through the centre of the earth and joins the North Pole and South Pole is called the Axis. The earth rotates on its axis from West to East. 2. EQUATOR: The imaginary circle which divides earth into two halves is called the equator.it is the biggest latitude. 3. POLES : The end points on the axis of rotation are termed as the poles of the globe. 4. GRIDS : Grids are the net or the squares formed by the latitudes and the longitudes ll ANSWER THE FOLLOING 1 What is a globe? A globe is a spherical model of the Earth with a map in its surface. 2 Who is a cartographer? A cartographer is the person who draws maps. 3 How does the scale of a map help us? The scale of a map helps us to find out the actual distance between two places with regards to the distance shown on the map. 4 List two advantages of a map. A map helps us to study small places, countries, oceans and even continents. It can be carried easily from place to place It is easier to identify regions in a map. 5 What are the draw backs of a globe? It is inconvenient to carry it around. It does not give us minute details about a place.

2 6 Differentiate between longitudes and latitudes Latitudes Longitudes Imaginary circles around the Earth They run from West to East Imaginary semi circles on the Earth. They run from North to South Lines are parallel to each other Lines are not parallel to each other but it joins North poles and South poles. The lines are not of same length Lines are called Parallels Lines are used for measuring distance Lines are of the same length Lines are called Meridians Lines are used for measuring local time Ill NAME THE FOLLOWING 1 The movement of the earth on its axis Rotation 2 The end points of the axis Poles 3 The two halves of the earth, when divided by the equator Northern Hemisphere, Southern Hemisphere 4 The place through which Prime Meridian passes Greenwich in London 5 The unit of measurement of longitudes and latitudes Degrees.
