Human migration is the movement of people from one place to another, intending to settle, permanently or temporarily, at a new location (geographic region). The person who migrates is known as the Migrant. It has a big impact on the population growth of a region. It may be interpreted as a spontaneous effort to achieve a better…
The human population is highly concentrated in the world. About 90% of the world’s population lives in just 10% of the area. 10 most populous countries contribute 60% to the world’s population. What affects the distribution of population around the earth? Let’s find out. The pattern of population distribution: About 90% of the world’s population…
Understanding the patterns of population distribution is one of the key areas of study in Human geography. In this chapter, we shall study the basics of Population dynamics and then in the later chapters we shall study the impact of migration and settlement patterns of population. Density of Population: The density of Population is the…
The term Geography is derived from two roots in the Greek language: ‘Geo’ (earth) and Graphos (description). More formally, Geography is generally defined as a relationship between the earth’s physical environments with humans. Scholars define geography as, “the description of the earth as the abode of human beings”. Did you Know? Eratosthenes, a Greek scholar (276-194…

Geologists and seismologists have been concerned about what constitutes the earth. Earth is not a homogeneous solid ball; it consists of different layers with different characteristics. Various processes in the earth’s interior affect the landforms, which indirectly affect people’s lives. Thus, we study the interior of the earth as it helps in: Sources of Information…
Latitude and longitude are geographical coordinates on the Earth that determine the location of any place on the Earth. The latitudes and longitudes are angles that uniquely define points on the Earth. Both the latitude and Longitude are measured in Degrees as they represent angular distances. Each degree is further divided into minutes (‘), i.e.,…
In order to understand earth, which is the prime focus of Geography as a discipline, we must first understand the origin of Earth. However, to understand earth we must understand the origin of our solar system and the Universe in general. There are various theories which gave the basis for the origin of the Universe. …
Geomorphology is a part of Earth Science that studies changes on the Earth’s surface and the forces and processes that develop them. It deals with the characteristics of the Earth’s surface and all the geological processes that try to change it over a period of time. The earth’s crust is dynamic. It moves vertically as…
Continents cover 29% of the surface of the earth and the remainder is under oceanic waters.The position of Continents and Oceans bodies has not been constant but it has been changing in the past. This chapter deals with the various theories related to the movement of the ocean and Continents. For a long time, many…
