The Earth’s interior comprises different layers with varying physical properties and compositions. The layered structure of the Earth has been interpreted based on the studies of seismic waves, magnetic fields, meteorites, and other physical properties. Internal Structure Based on Chemical Composition Base on the chemical composition, the internal structure of the earth is divided majorly … Read more
What is a tsunami? A tsunami is a large and powerful ocean wave that is caused by a sudden disturbance, such as an earthquake, volcanic eruption under the sea, or underwater landslide. When an earthquake or other event disrupts the ocean floor, it displaces a large amount of water, which then radiates outwards as a … Read more
Apophysis Definition “Apophysis or epiphysis is an offshoot from a larger, intrusive body.” In geology, an apophysis is a projection or extension of a geological structure, such as a vein, a dike, or a mineral deposit, that extends from the main body into surrounding rocks. The term “apophysis” comes from the Greek word “apophȳsis,” which … Read more
What is permeability? Permeability is the ability of the rock, sediment, or soil for transmitting a fluid. It is a measure of the relative ease of fluid flow under unequal pressure and is a function only of the medium. This property of the rock is due to the interconnected voids present in the rock or … Read more
Weathering of rocks is due to the processes of mechanical disintegration and chemical decomposition. It can happen due to different physical, chemical and biological factors of nature.
Chemical weathering is the process by which rocks are decomposed by chemical processes like Hydration, reduction, oxidation, carbonation, etc. All these can be discussed under chemical factors.
Coral reef generally refers to a marine ecosystem in which the main organisms are corals that house algal symbionts within their tissues.
Unconformity represents a period of erosion and deposition. Throughout Earth history, the deposition of sediment has been interrupted again and again. All such breaks in the rock record are called unconformities.
What is lake? Any inland body of standing water occupying a depression in the Earth’s surface, generally of appreciable size (larger than a pond) . The water may be fresh or saline. The term includes an expanded part of a river, a reservoir behind a dam, or a lake basin intermittently or formerly covered by … Read more
Weathering is the breakdown and alteration of rocks at Earth’s surface through physical and chemical reactions with the atmosphere and the hydrosphere. Weathered rock or minerals will break down into smaller units and eventually disintegrate into even smaller particles. This takes place in two major ways: physical (or mechanical) and chemical weathering; to a lesser … Read more
