What do you Understand by a Volcano? Write its Causes and Types.

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

Explain the Erosional Topographies Formed by Wind.

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

Discuss the nature and Scope of ​​Geomorphology.

Geomorphology is the study of the surface features of the Earth, including its topography and landforms. The term geomorphology comes from Greek roots meaning “earth movement.” It is a broad field that focuses on the variety of ways that landforms on our planet are formed. Geomorphologists study how erosion and deposition affect the landscape, how … Read more

Explain the Concept of Plate Tectonics Related to Mountain Formation.

Meaning of Plate Tectonics The term “plate” was coined by Canadian geophysicist J.T. Wilson in 1965 to refer to a solid landmass on Earth. The study of the nature and movement of these plates is known as plate tectonics. The concept of plates emerged from two observations: (1) The movement of continents and (2) The … Read more

Describe the Principle of Plate Tectonics.

Basic Concepts of Plate Tectonics The concept of plate tectonics is based on the following three main assumptions: (i) The ocean floor constantly expands, and a new oceanic crust forms at active ocean ridges, while its destruction occurs in craters. (ii) The surface area of the Earth is constant, and the radius of the Earth … Read more

Describe the Cycle of Erosion Given by Penck.

Penck’s Erosion Cycle According to Penck, “The phase and rate of upliftment of landforms and the sum of mutual relations in degradation are intertwined.” Mr. Penck has observed upliftment occurring at different rates and has divided the stages of evolution of landforms into three parts, as follows: Afasti Jinde Intiwak Lung – In this stage, … Read more

Describe the Landforms Formed by Internal Volcanic Action.

The landforms created by internal volcanic activity are mainly basaltic lava flows, which occur when lava erupts from within the earth. Basaltic lava is a type of lava that has low viscosity and flows easily downslope, creating large sheets of rock that can extend for miles. The sheets of basaltic lava can be up to … Read more
