Question 4:Distinguish between the followings.

(i) Primary activities and tertiary activities

Answer :

Primary activities : Those activities which include the extraction and production of natural resources are called primary activities. Examples are agriculture, fishing.

Tertiary activities : Those activities which include the manufacturing of primary and secondary products are called tertiary activities. Examples are transport services, banking services

(ii) Subsistence farming and intensive farming.

Answer :

Subsistence farming : This type of farming is practiced to meet the needs of the farmers family. Low level off technology and household labor are used to produce a small output.

Intensive farming : The farmer cultivates a small plot of land using simple tools and more labor.

Major crops include rice, wheat, maize, pulses etc.

Question 5:(i) Collect seeds of wheat, rice, jowar, bajra, ragi, maize, oilseeds and pulses available in the market. Bring them to the class and find out in which type of soil they grow.

Answer :
  • Soils with a clay loam or loam texture, good structure and moderate water holding capacity are ideal for wheat cultivation.
  • Soils with good water retention capacity with high amount of clay and organic matter are ideal for rice cultivation.
  • Jowar grows well in sandy loam soils having good drainage.
  • Bajra grows best in black cotton soil, sandy loam soil having well drainage.
  • Ragi is cultivated on a variety of soils ranging from rich loam to poor shallow upland soils. It prefers porous and well drained loam to light red loam and sandy loam soils of good fertility but reasonable water holding capacity.
  • Maize grows in soils with good organic matter content having high water holding capacity with neutral pH are considered good for higher productivity.

Oilseeds and pulses are grown in loamy soil.

Question 5:(ii)Find out the difference between the life style of farmers in the USA and India on the basis of pictures collected from magazines, books, newspapers and the internet.

Answer :
  1. In india, 80% of the populaion is involved in farming. In USA, only a small number of people are involved in farming.
  2. the size of an average farm is small in size, around 2.3 hectares. In contrast, U.S. farm holdings are large, around 250 hectares.
  3. Indian farming is very much labor intensive, and most farmers use traditional methods of farming like plowing with bullocks. U.S. farming is mostly capital intensive with large-scale use of heavy and advanced machinery.
  4. Indian farming is still very much dependent on the weather and, consequently, is able to grow only two to three crops in a year. On the other hand, U.S. farms are able to grow multiple crops in one year.
