Points to Remember: The question requires identifying the four geographical regions with the highest population concentration, accounting for approximately two-thirds of the global population. The approach is primarily factual, relying on demographic data. Introduction: The global distribution of population is highly uneven. While humans inhabit every continent, a significant majority resides in specific regions. Understanding … Read more Name the four regions of the world where most (two-thirds) of the world’s population is concentrated.

Points to Remember: Definition and measurement of relative humidity. Factors affecting relative humidity. Effects of relative humidity on human comfort and health. Impact on various sectors (agriculture, industry, etc.). Methods for controlling relative humidity. Introduction: Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water … Read more Comment on relative humidity.

Points to Remember: Salinity is the saltiness or dissolved salt content of a body of water. Ocean salinity is influenced by a complex interplay of factors. Understanding these factors is crucial for managing marine ecosystems and resources. Introduction: Ocean salinity, typically expressed as parts per thousand (ppt) or practical salinity units (PSU), is a fundamental … Read more Mention the controlling factors of salinity in oceans.

Points to Remember: The atmosphere is a layered structure. Each layer has unique characteristics regarding temperature, composition, and function. The composition of the atmosphere is not uniform throughout all layers. Human activities significantly impact atmospheric composition. Introduction: The Earth’s atmosphere is a vital component of our planet, providing the air we breathe and protecting us … Read more Describe the composition of the atmosphere.

Points to Remember: Antipodal points are diametrically opposite points on the Earth’s surface. Continental distribution is not uniform; landmasses are concentrated in the Northern Hemisphere. Ocean distribution is largely complementary to continental distribution. The antipodal relationship reveals interesting geographical patterns and implications. Introduction: The Earth’s surface is divided into continents and oceans, a distribution far … Read more Explain the antipodal situation of continents and oceans on the earth.

Points to Remember: Elevation: Both ridges and ranges involve elevated landforms. Scale: Ranges are significantly larger and more complex than ridges. Linearity: Both generally follow a linear pattern, but ranges exhibit greater length and continuity. Formation: Both are formed by geological processes, primarily tectonic activity. Introduction: Mountains are prominent features of the Earth’s surface, rising … Read more Differentiate between a Mountain Ridge and a Mountain Range.
