Heartland and Rimland Theory Heartland theory states the power that control central Asia whereas Rimland gives the importance to the strip of coastal land that encircles Eurasia. Heartland and Rimland Theory were further discuss below Heartland Theory Mackinder had concluded from his study of global physical map that three time fourth of earth surface consisted … Read more
Introduction Sikkim has physical features like rivers and mountains and has a very rugged topography and flat lands. The major river of Sikkim Tista originates from Cholamu Lake, it makes various tributaries along the way as it goes. Rangit is the major tributary of Tista which originates from Rathong glacier. No one can imagine that … Read more
FLUVIAL LANDFORMS Fluvial landforms are the landforms either carved out (due to erosion) or built up (due to deposition) by running water and the running waters that shape them are called fluvial processes which include overland flow and surface flow. The geological works of fluvial processes or rivers are called three-phase work comprising erosion, transportation, … Read more
Rural-Urban fringe It is a zone of transition/discontinuity with mixed land uses it combines land use features of rural settings and urban settlements. It is located in an urban built-up area which is under the control of either a down area or a municipality/municipal corporation and countryside. It is an outcome of urban sprawl which … Read more
Pedogenesis Pedogenesis of Soil explains the factors and processes involved in the formation of soil. It involves the formation of soil from various factors such as weathering of rocks, influence of climate, geological movement, and activities of living organisms that shape the formation of soil. Factors controlling the formation of soil are: Parent rock Climate … Read more
Dynamic Regional Development Strategies Regional development strategies are a theoretical model that describes and explains the rational and efficient location of resources in a given geographical region to change its underdeveloped economy into a developed economy. This theories are broadly classified into two categories: ⦁ THEORY OF BALANCED GROWTH ⦁ THEORY OF IMBALANCE GROWTH THEORY … Read more
Exploring the Hypsometric curve The hypsometric curve describes and explains the relative distribution of altitude and depth on the surface of the earth concerning mean sea level. Mt. Everest is the highest point and Marina Trench is the lowest point. 29% of the earth is land surface, Asia, and Africa are the largest continents, … Read more
Global Rainfall Patterns: Exemplifying the Dominance and Diversity Global Rainfall patterns are highly correlated with atmospheric humidity while atmospheric humidity is closely related to temperature through the process of evaporation. The region having abundant surface water for evaporation and with high temperatures receives a higher amount of rainfall. Equatorial regions are one example of such … Read more
Unlocking the Mysteries: Evaporation vs. Boiling Evaporation and boiling are two common processes that involve the transformation of a substance from a liquid state to a gaseous state. While they both involve the conversion of a liquid into vapor, they differ in several important aspects, including the mechanism, temperature, and energy requirements. In this essay, … Read more
Introduction Planetary Winds: Planetary winds, also known as the global wind system or the atmospheric circulation, are large-scale wind patterns that occur on a global scale and play a crucial role in shaping Earth’s climate and weather. these winds are driven by the differential heating of the earth’s surface by the sun and the rotation … Read more
