Frequently Asked Questions
What is the difference between population growth and population change?
Why is the density of population high in the plains and low in mountainous regions?
Plains offer fertile soil for agriculture, flat land for building infrastructure, and better transport networks, whereas mountainous regions have rugged terrain, harsh climates, and poor accessibility.
What are push and pull factors in migration?
Push factors are conditions like unemployment, poverty, or natural disasters that force people to leave an area, while pull factors are attractive conditions like better jobs, education, and healthcare that draw people to a new destination.
