Landforms and their evolution Landforms are the natural process of the earth’s surface that includes mountains, hills, plateaus, and plains. Landforms consist of their own physical shape, size, and materials. These are the results of certain geomorphic processes and agents. Landforms may change their shape, size, and nature after their Read more…

All these orbit the sun to form the Solar System. Sun is our motherly and nearest star, which creates energy from nuclear reactions Read more…
Seafloor Spreading The concept of seafloor spreading was proposed by Harry Hammond Hess in 1961 (an American geologist). He discovered the mid-Atlantic ridges i.e. mid-ocean ridges. It is a geologic process in which tectonic plates splits apart from each other. The process of seafloor spreading occurs at mid-oceanic ridges, in Read more…
Atmosphere: Composition and Structure Atmosphere of Earth The atmosphere is an envelope of gases surrounding the earth, these gases are commonly called air. The air is one of the necessary conditions for the existence of life on the planet. The atmosphere of Earth protects life on Earth. The atmosphere is Read more…

List of Important Local Winds local winds blow over a limited area. They are caused due to influence of local pressure gradient and terrain. The local winds blow between small, low, and high-pressure systems. These winds are influenced by local geographical conditions like distance from the ocean, lake, or mountain Read more…
Plate Tectonics Plate tectonics: The term was first coined by JT Wilson in 1965. After the evolution of the concept of the “continental drift hypothesis” and “seafloor spreading” a broader concept of “plate tectonics” was developed in 1967. The theory of Plate Tectonics was introduced independently by McKenzie, Parker, Morgan, Read more…
Earthquakes (also called quakes, tremors, or temblors) A sudden movement of Earth’s crust is caused by the release of stress accumulated along geologic faults or by volcanic activity. In simple words, the earthquake refers to the shaking of the earth. Mainly it is a natural event caused due to release Read more…
