Due to the erosion of glaciers, various features are formed on mountains. 1 ) Ice Depressions – When glaciers move down from high mountain areas, they create depressions on the mountain slopes. These depressions gradually become deep troughs. Over time, these troughs become so deep and wide that glaciers are formed and nourished by them. … Read more
Classification of Rocks There are many types of rocks that can be classified into three main categories based on their fundamental nature and origin of formation: Igneous rocks Sedimentary rocks Metamorphic rocks” Related- Explain the composition of the Earth’s Womb. Describe the Principle of Plate Tectonics. Describe the Concept of Normal Erosion Cycle Propounded by … Read more
There are the following ideologies about the interior of the earth (1) The Innermost Hypothesis of the Earth’s Interior German geophysicist Suess proposed the idea that the melting point of any substance increases with an increase in pressure, but experiments have shown that this is only possible up to a certain extent. No mineral substance … Read more
Volcanic eruptions are activities that involve the movement of lava from the interior of the Earth to the Earth’s surface. They are divided into two categories: Intrusive: In this process, the underground lava does not reach the surface but cools below the surface, forming different structures such as dikes, sills, laccoliths, and volcanic necks. Extrusive: … Read more
An earthquake is a phenomenon where the land vibrates or moves back and forth. This movement is caused by waves of flexible compression passing through the earth’s crust. Essentially, an earthquake is a disturbance of the earth’s crust that causes the land to move in a back-and-forth motion. When an event occurs inside the earth, … Read more
Topographies created by Wind Erosion Kshatrak– Due to the action of air in desert regions, many rocks appear like a plant called ‘Kshatrak.’ This type of rock texture is called Chhatrak. There is a canopy of granite near Jodhpur (Rajasthan), which is called Nata in the Sahara desert. These are formed by natural wind erosion, … Read more
Prof. A. Wegener was a German meteorologist who proposed a hypothesis to explain the climate of the past. Prominent evidence shows that tropical regions of India, Brazil (South America), South Africa, and Australia were glaciated during the coal epoch. This is only possible if we assume that in the past, the distribution of climate belts … Read more
There are many relief features on Earth, which can be classified into three categories. The first-order relief features include continents and oceans. The second-order relief features include mountains, plains, and plateaus, which are formed by internal movements of the earth and exogenous waters. The third-order relief features include valleys, hills, deltas, and glaciers, which are … Read more
The velocity of air also depends on air pressure. The gradient of air pressure affects the speed of air. When the gradient of air pressure decreases, the wind blows at a high speed. Isobaric lines indicate the gradient. If the isobars are close to each other, then the air pressure is high and the winds … Read more
In physical geography, the study of natural factors and processes is conducted. It is a significant component of geography and encompasses the geosphere, atmosphere, hydrosphere, and biosphere. Physical geography focuses on the movement of water and air, the changes to the earth’s surface due to internal and external influences, and the origins and destructions of … Read more
