CHAPTER-4  MAPS

Answer the following question

Question a:-What are the three components briefly. of a map?
Answer:- The three components of a map are – Distance, Direction & Symbol.

Question b:- What are the four cardinal directions?
Answer:- Cardinal Directions are the most commonly used forms of direction and they are North, South, East and West. The four equal divisions – Northeast, Southeast, Southwest and Northwest – are called Primary Inter-cardinal directions.

Question c:- What do you mean by the term ‘the scale of the map’?
Answer:- The scale of the map shows the actual distance as represented by one unit of measurement on the map. For example; if the scale of the map shows 1 cm = 10 km, this means 5 cm on the map is equal to 50 km in the real world.

Question d:- How are maps more helpful than a globe?
Answer:- A globe can be useful when we want to study the earth as a whole. But if we want to study only a part of the earth, e.g. a continent or a country, globe is not helpful. A map is a representation or a drawing of the earth’s surface or a part of it drawn on a flat surface. It gives more information than a globe.:

Question e:Distinguish between a map and a plan.
Answer:– A map is a visual representation of an area highlighting relationships between elements of that area such as objects, regions, and themes. Plans are a set of two-dimensional diagrams or drawings used to describe a place or an object, or to communicate building or fabrication instructions.

Question f:- Which map provides detailed information?
Answer:- Large scale maps are the one that provide detailed information.

Question g:- How do symbols help in reading maps?
Answer:- It is not possible to draw actual shape and size of different features (like. buildings, roads, bridges) on a map, hence they are shown by using certain standard letters, shades, colors, pictures and lines. These symbols give a lot of information in a little space. Using these symbols, maps can be drawn easily. The use of symbols makes maps simple to read.

CHAPTER – 2 GLOBE: LATITUDES AND LONGITUDES

 


GLOBE: LATITUDES AND LONGITUDES

1: Answer the following questions briefly.

Question a:What is the true shape of the Earth?
Answer:- Earth is not a sphere it is slightly flattened at the north and south pole and bulge in the middle.

Question b:What is a globe?
Answer:- Globe is a true model (Miniature form) of Earth. The globe is not fixed. It can be rotated the same way as a topspin or a potter’s wheel is rotated. On the globe countries and continents and oceans are shown in their correct size

Question c: What is the latitudinal value of the Tropic of Cancer?
Answer:- The latitudinal value of tropic of cancer is 23 1/2° North in the Northern Hemisphere.

Question d:What are the three heat zones of the Earth?
Answer:- There are three types of heat zones in the Earth they are, Torrid Zone Temperature zone, Frigid zone.

Question e:- What are the parallels of latitude and meridians of longitudes?
Answer: All parallel circles from the equator up to the poles are called parallels of latitudes.  The lines of reference running from the north pole are called meridians of longitudes.

Question f: Why does the Torrid Zone receive the maximum amount of heat?
Answer:- The area between tropic of cancer and tropic of Capricorn The midday sun is exactly overhead at least once in a year on all latitudes in this area receives the maximum amount of heat

Question g:- Why is it 5.30 P.M. in India and 12.00 noon in London?
Answer:-  In India, the longitude of 821/2° E (82° 30E) is treated as the standard meridian. The local time at this meridian. The local time at this meridian is taken as the standard meridian for the whole country. It is known as the Indian Standard Time (IST) India located east of Greenwich at 82° 30E in 5 hours and 30 minutes ahead of GMT so it will be 5:30 in India when it is 2 noon in London
