Ans. 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, it is of little help.
Map is the 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.
(e) Distinguish between a map and plan.
Ans. A map is a representation or a drawing of the earth's surface or a part of it drawn on a flat surface, according to a scale.
A plan is a drawing of a small area on a large scale. There are certain things we sometimes want to know, e.g. length and breadth of a room, which cannot be shown in a map. So we refer to drawings drawn to scale called a plan.
(f) Which map provides detailed information ?
Ans. Large scale maps provide detailed information.
