In this module we will deal with basic concepts of time and distance, speed, Average speed, conversion from km/h to m/s and vice versa. This chapter will form the basis of further concept of relative speed which is used in train and boat problems. Important Formulas Speed=Distance/Time Distance=Speed×Time Time=Distance/Speed To convert Kilometers per Hour(km/hr) … Read more
Physical Factors: (a) Terrain, Topography, and Altitude dependent on the geo-ecological conditions; terrain, topography, slope and altitude. paddy cultivation requires leveled fields, tea plantations perform well in the undulating topography in which water does not remain standing. Orchards of coconut are found at low altitudes, preferably closer to the sea level, while the apple orchards … Read more
The Silent Erosion: Understanding and Combating Sheet Erosion Sheet erosion, a seemingly innocuous process, silently steals away the fertile topsoil that sustains our agricultural lands and ecosystems. This insidious form of soil degradation, often overlooked in favor of its more dramatic counterpart â gully erosion â poses a significant threat to global food security and … Read more
What is Gully Erosion? Gully erosion is a type of SoilSoil erosion that occurs when water flows over land and creates channels or gullies. These gullies can be small or large, and they can cause significant damage to land and property. Gully Formation and Development Causes of Gully Erosion Concentrated Water Flow Land Use and … Read more
The Invisible Hand: Frictional Force and its Impact on Wind Movement Wind, a seemingly effortless flow of air, is a complex phenomenon driven by a delicate balance of forces. While pressure gradients and the Coriolis effect play significant roles in shaping wind patterns, a less obvious but equally crucial factor is frictional force. This article … Read more
