(ii) Name the factors influencing agriculture.

Ans. The factors influencing agriculture are the favourable topography of soil and climate.

(iii) What is shifting cultivation? What are its disadvantages?

Ans. Shifting cultivation or slash-and-burn cultivation is a type of farming activity that involves clearing a plot of land by felling trees, burning the felled trees, mixing the ashes with soil, and then growing crops like maize, yam, potatoes, and cassava on the cleared land. After the soil loses its fertility, the land is abandoned and the cultivator moves on to a new plot. This type of farming has the following disadvantages.

(a) Leads to deforestation
(b) Soil becomes susceptible to erosion due to deforestation
(c) Soil loses its fertility due to the erosion of the topsoil

(iv) What is plantation agriculture?

Ans. Plantation agriculture is a type of commercial farming where a single crop of tea, coffee, sugarcane, cashew, rubber, banana, or cotton is grown. A large amount of labour and capital is required in this type of farming. The produce is either processed on the farm itself or in nearby factories. Major plantations are found in the tropical regions of the world, like rubber in Malaysia, coffee in Brazil, tea in India and Sri Lanka, etc.

Ans. Distinction between Primary & Tertiary Activities:

Primary Activities

Tertiary Activities

Examples are - Transport, communication,

ii. Examples are - Extraction (mining), gathering, fishing, agriculture.

ii.  Examples are - Trade, banking, media, etc.

Ans. Distinction between Subsistence & Intensive Farming:

Subsistence Farming - This type of farming is carried out to meet the needs of the farmer’s family. It is done generally on a traditional basis using low levels of technology and household labour. A variety of crops are raised in small quantities on a small plot of land.

Intensive Farming - It is a kind of subsistence farming only where a farmer cultivates a small plot of land by simple tools and more labour. Climate with a large number of day’s sunshine and fertile soil help in growing more than one crop on the same plot in a year. This type of farming is common in the thickly populated areas of the monsoon regions of south, southeast, and east Asia
