Seismic waves, also known as earthquake waves, are waves of energy that travel through the Earth’s crust as a result of an earthquake or other seismic activity. These waves can be divided into two main categories: Body waves and Surface waves. Body waves travel through the Earth’s interior, while surface waves travel along the Earth’s …
Earthquakes are typically caused by the movement of tectonic plates, which are large sections of the Earth’s crust that move relative to each other. When two plates are moving towards each other, one may be forced beneath the other in a process called subduction. This can lead to the buildup of stress in the crust, …
Coal is an important fossil fuel in India and is primarily found in sedimentary rocks of the Damodar Valley, Jharkhand, and West Bengal regions. The major coalfields in India are: Jharia coalfield: Located in Jharkhand, it is the largest coalfield in India and one of the largest in the world. The coalfield covers an area …
Conventional sources of energy are those that have been traditionally used to meet our energy needs and are typically non-renewable, meaning that they cannot be replenished on a human timescale. The major conventional sources of energy include: Fossil Fuels: Fossil fuels are the remains of ancient plants and animals that have been buried under the …
Earthquakes are a natural phenomenon that occur when the Earth’s crust experiences a sudden release of energy, resulting in seismic waves that propagate through the ground. These waves can cause shaking and ground displacement, which can lead to damage to buildings and other structures, landslides, and tsunamis. Earthquakes occur at the boundaries between tectonic plates, …
Volcanoes are found all around the world, but their distribution is not random. Most volcanoes are found along plate boundaries, which are the areas where tectonic plates meet and interact. There are three main types of plate boundaries: Divergent boundaries: These are areas where two tectonic plates are moving away from each other, and new …
India has a diverse mix of energy resources, including both commercial and non-commercial sources. Commercial sources of energy in India include coal, crude oil, natural gas, and electricity. India is the third-largest coal producer in the world, with significant reserves located primarily in the states of Jharkhand, Odisha, and Chhattisgarh. India also imports significant amounts …
Metals occur in nature in various forms, including: Native metals: These are metals that occur in pure form in nature. Examples include gold, silver, copper, and platinum. Ores: Most metals occur in the form of minerals called ores, which contain one or more metal compounds. The metal is extracted from the ore by various processes, …
There are several types of volcanoes, each with its own unique characteristics: Shield Volcanoes: Shield volcanoes are broad, gently sloping volcanoes with a low profile. They are typically formed by the eruption of basaltic lava, which has low viscosity and can flow easily and quickly. Shield volcanoes can be very large, and are often associated …
Coal reserves are found in many parts of the world, with significant deposits located in countries such as the United States, China, Russia, India, Australia, and South Africa. The United States has the largest coal reserves in the world, accounting for approximately one-fourth of global reserves. The majority of U.S. coal reserves are located in …
