Question

1). Why is the population density higher in the northern plains and Kerala?

AND

2).Which are the three main processes responsible for a change in population?

Answer 1

population is higher because northern plains and Kerala gave very fertile land. they are rich in humus .so people can grow their crops .thats why it is fertile

Answer 2

ANSWER:

• Kerala and Northern plains have a very high population density due to flat plains with fertile soils and ample rainfall.

• 3 main processes of population change are birth rates, migration and death rates  

EXPLANATION:  

• The rich soil cover together with favourable climate and copious water supply made Kerala and the northern plains agriculturally very productive. Due to this factor, the population density is also the highest in these regions amongst all other regions ofof India. Moreover Kerala and Northern plans have flat terrainsthat supports high density of population .

• Birth rate is the number of live births/1000 persons and death rate is the number of deaths/1000 persons. A higher birth rate together with a lower death rate leads to population increase. Due to progressions in nutrition and healthcare, death rates have reduced over the years. The birth rates too have declined owing to persistent campaign towards family planning and better awareness amongst people. Migration is an additional factor that changes the population size. Shifting of people from one domicile to another seeking livelihood is termed as migration. Migration within the nation is termed as internal migration, while that between 2 nations is known as international migration. Internal migration does not change the population size; however it alters the population composition of a specific area.
