3. Write short notes on.

The following are the important physical factors, which can be responsible for the development of fishing.

The important factors responsible for the development of commercial lumbering in the above areas are as follows.

4. Give geographical reasons.

Cool climate of Canada, well developed transport facilities for the movement of logs, use of machinery for logging, large demand in local and international market for paper and pulp industries, limited development of other economic activities due to extreme cold climate are the other factors responsible for lumbering in Canada.

5. Differentiate between.

6. Answer the following questions in detail.

7. On an outline map of the world, show the following with appropriate symbols and prepare-an index.

(iv) Fishing can develop only in those areas in the oceans where continental shelf is broad and shallow, meeting of cold and warm ocean water currents and availability plankton food for fish, cool climate etc. Since these physical factors are found only certain areas, so fishing occupation is developed in certain areas only. For example, Dogger banks in Europe or Grand Banks in north eastern part of USA etc.

(v) Agriculture, lumbering, mining and animal husbandry are the primary economic activities found in Europe.
(vi) A star (★) symbol for mining is shown for the production of mining in seas and oceans.
(vii) Mining is not found in the continent of Antarctica.
(viii)The world’s fishing is mostly carried out in the Atlantic Ocean.
(ix) Agriculture, mining, fishing, lumbering and animal husbandry are the primary economic activities found to the south of Tropic of Capricorn.
(x) Agriculture, fishing, and lumbering are the economic activities found in the islands of South East Asia.
(xi) Out of the four continents less agriculture is practiced in the continent of Australia.

(xii) Considering latitudinal extent except North Africa agricultural activities are important economic activities in latitudinal belt 8° to 50° North parallel of latitudes in the northern hemisphere and 20° to 45° latitudes in the southern hemisphere.

Can you tell?

Some of the important problems are as follows.

Find out.

The objectives and components of the Act are as follows:

In 1991, the Act was amended to include plants in its definition of wildlife. Until then, for almost two decades, protection of plant life was not on agenda.

Think about it.

(iv) Lumbering is practiced in the areas where forest grows.

(v) Commercial lumbering is not developed in Equatorial region due to following reasons.

(iv) Along the western coast of Africa, the continental shelf is broad and water is shallow.

(v) The southern coastline is the traditional area of fishing in Greenland.

(v) In a zone between 5° North to 5° South latitudes, animal husbandry is not found on large scale. This zone has equatorial climate, so dense forest growth and inhospitable climate and lack of good quality grass are the reasons for no development of animal husbandry in above mentioned zone.

(vi) For the development of animal husbandry, climate is more important factor. In eastern part of Australia, the climate is suitable for the growth of good quality grass, therefore, animal husbandry is more developed.

(vii) The arid regions of interior of the continents receive very low rainfall.

(iv) Yes, we can relate mining with the economic development of the country because minerals provide raw material to many industries, especially heavy industries. Therefore, countries rich in minerals have more economic development. For example, the USA, Developed countries of Europe.
