Man-made Disasters Man-made Disasters are human-made occurrences that can directly or indirectly pose serious hazards to the health and/or welfare of the general public. They can be caused purposefully or accidentally. Man-made catastrophes provide a particularly difficult challenge because of their unpredictable occurrence, which must be managed by monitoring, appropriate preparation, and timely response. In order to inform the public on the causes and impacts of man-made disasters as they pertain to emergency planning, information on the main sources of these catastrophes has been provided here. 1. Social-Political Risks • Crime • Arson Arson is the act of starting a fire with the purpose of causing harm. Initially only referring to the setting of fire to buildings, the concept of arson was eventually broadened to also encompass the setting of fire to private property, automobiles, and bridges. The main reason for flames in data repositories is arson. Accidental fires caused by human

Natural disasters are catastrophic events caused by natural processes on the earth. Examples include floods, storms, tsunamis, and earthquakes. The world has been subjected to a number of natural calamities over the course of its billions of years. Several mass extinction events have occurred, with catastrophic repercussions for various surviving species. To find out the solution to this and more information on natural disasters, visit this blog! What exactly is a natural disaster? A natural disaster is described as "a major event caused by natural processes on Earth that causes significant environmental degradation and loss of life." A natural danger is typically preceding a natural disaster. The January 26, 2001 Gujarat Earthquake, for example, was a natural disaster. Natural hazards lurk beneath the active fault lines that run through Gujarat. Anthropogenic causes, on the other hand, can cause or influence certain natural hazards. Landslides can be caused by a variety of f

What is Lunar eclipse? Lunar eclipses occur when the Earth passes between the sun and the moon, producing a shadow on the moon's surface. They can only occur during a full moon and are a favourite event for skywatchers worldwide because they do not require any additional equipment to enjoy (unlike solar eclipses).  Earth will witness two moon eclipses in 2023. On May 5, 2023, a penumbral lunar eclipse was visible across regions of Africa, Asia, and Australia. The second and last lunar eclipse of 2023 will be a partial lunar eclipse on October 28 that will be visible across areas of the Eastern Americas, Europe, Africa, Asia, and Australia. Check out our lunar eclipses 2023 guide to find out when, where, and how to see this year's lunar eclipses. A lunar eclipse occurs when Earth blocks sunlight from reaching the moon, casting a shadow across its surface. During a lunar eclipse, the sun-blocking Earth creates two shadows on the moon: the umbra, which is a full, dark shadow, and

What is Solar Eclipse? A solar eclipse is a breathtaking sight and a once-in-a-lifetime astronomical phenomenon. Each one is only viewable from a specific location. The Moon completely eclipses the Sun. A solar eclipse occurs when the New Moon passes between the Sun and Earth, blocking the Sun's rays and creating a shadow on sections of the Earth. Because the Moon's shadow is too small to encompass the entire globe, it is always limited to a specific area (see map drawings below). This area fluctuates throughout the eclipse because the Moon and Earth are constantly in motion: the Earth rotates around its axis while orbiting the Sun, while the Moon orbits Earth. This is why solar eclipses appear to move from one location to another. Types There are four types of solar eclipses. The magnitude of the eclipse, or how much of the Sun's disc is eclipsed, is determined by where the Moon's shadow falls on Earth. ●Partial solar eclipses occur when the Moon only partially obscure

What is a black hole? A black hole is a region of space where gravity is so strong that even light cannot escape. Because stuff has been compressed into a small space, gravity is extremely powerful. This can occur when a star dies. People cannot perceive black holes because no light can escape. They are undetectable. Space telescopes equipped with specialised equipment can aid in the discovery of black holes. Special technologies can observe how stars in close proximity to black holes behave differently from other stars. What Size Are Black Holes? Black holes can be large or small in size. Scientists believe that the smallest black holes are as small as one atom. These black holes are extremely small in size but have the mass of a massive mountain. What Causes Black Holes? According to scientists, the smallest black holes created when the cosmos first began. Stellar black holes form when the core of a massive star collapses in on itself. When this happens, a supernova occurs. A superno

What is the ozone layer, and why is it important? Human activity has depleted this protective layer of the stratosphere, but scientists believe it is on the mend. The ozone layer is critical to making the world habitable for humans and other creatures. The ozone layer absorbs the majority of the sun's UV energy high in the atmosphere, between 10 and 50 kilometres above the earth's surface. However, people were generating enormous amounts of compounds that destroyed the ozone layer during the 1970s, 1980s, and 1990s. As a result, ozone holes formed near the Earth's poles, exposing life to higher levels of UV light and increasing the risk of skin cancer in humans. The world joined together in the 1980s to forge an international accord to cut – and eventually eradicate – emissions of these depleting pollutants. Political agreements were extremely effective. Since then, global emissions have decreased by more than half. Emissions of ozone-depleting chemicals have decreased by m

How did the Earth earn its name? The original namer of Earth, like many other solar system objects, has long been lost to history. Linguistics, on the other hand, provides a few hints. In Anglo-Saxon, one of the parent languages of English, Ertha is an approximate spelling for "the ground" (meaning, the earth upon which we stand). The word "Anglo-Saxon" refers to a cultural group that resided in modern-day England and Wales between the fifth century and the Norman Conquest of 1066, shortly after the Roman Empire dissolved. Ertha in Anglo-Saxon "means the ground on which you walk, the ground in which you sow your crops," according to Gillian Hovell, a freelance archaeologist and historian known as "The Muddy Archaeologist." According to Hovell, Ertha is also linked to a place where life emerges and possibly to ancestors who are buried in the ground. However, depending on the culture, the name's meaning can alter. Other common modern titles for

Formation of Clouds What is a Cloud? Clouds are composed of water droplets or ice crystals that are so small and light that they may float in the air. But how does the water and ice that builds up clouds enter the atmosphere? And why do various sorts of clouds ? Water vapour evaporates into the atmosphere The water and ice that make up clouds travel into the sky as water vapour, the gas form of water, in the form of air. Water vapour enters the atmosphere mostly through evaporation, which occurs when liquid water from the ocean, lakes, and rivers evaporates and travels in the air. When air rises in the atmosphere, it becomes cooler and less pressurised. Some of the water vapour condenses when the air cools. Water vapour condenses as air pressure lowers. The vapour condenses into little water droplets, forming a cloud. A Cloud is formed when water vapour condenses When water vapour has a particle to condense on, it is easier for it to condense into water droplets. These particles, which

In this post we saw about Volcanoes...  A volcano is a landform (typically a mountain) where molten rock erupts from the planet's surface. There are numerous active volcanoes all around the world. We will study about the definition, formation, and types of volcanoes in this post. What Exactly Are Volcanoes? A volcano is a landform, a mountain, where molten rocks erupt from the planet's surface. The volcano mountain descends to a lake of molten rocks beneath the earth's surface. Volcanic eruptions The surface eruption of magma from the earth's upper mantle creates a volcano mountain. The magma that explodes to the surface, forming a lava flow and depositing ash. As the volcano erupts further, a new layer of lava is deposited to the surface, eventually becoming a mountain. Volcanoes in Various Stages They are typically conical, but there are a range of shapes based on: The material's nature erupted. The nature of the eruption The amount of change that has occurred sin

Hello friends.. In this post we will saw some facts about our Sun First we must know.. What exactly is tha sun..?  Our sun is a spherical ball of helium and hydrogen atoms; it is the star of our planet and others. In other words, a star is a large mass within which nuclear fusion and fission must occur. Because the Sun possesses all of these characteristics, we refer to it as the Nakshatra. In this universe, there are countless stars like our sun. The sun spins around its own axis This Sun revolves around the Earthfrom west to east. It could take between 225 and 300 million years to complete its orbit around the Milky Way. The diameter of the sun This sun is so massive that about 1,30,000 Earths like ours can fit inside it. The Sun's Age According to researchers, the sun is now 5 billion years old. This is a star's middle age, and in a few thousand years, the sun will enter its last age as hydrogen begins to burn. The sun's temperature Our Sun is a yellow star with a temper

Moon Beginning: The prevailing scientific theory holds that our Moon was formed by a catastrophic massive impact. Earth was a completely different place 4.5 billion years ago, shortly after the planets in our solar system formed, burning red with rivers and seas of lava. The solar system was still cluttered with formation detritus. Earth and another small planetary body orbited the Sun in the same region of our solar system for millions of years. The orbit of the small planetary body crossed Earth's course, and the two crashed, breaking the impactor. Its remains were either flung into space or absorbed by the Earth. The crashing object's core merged with the Earth's thick core. The ring of vapour, dust, and molten rock clumped (accreted) during a brief period of time, probably a hundred years or fewer. The greatest clumps gathered more and more particles, getting larger and larger as time passed, eventually forming our Moon. The Moon was 15 times closer to Earth shortly aft

Do you know about STARS..?  Let's know some details about stars..... STARS Stars are the most well-known astronomical objects, and they are the primary building blocks of galaxies. The age, distribution, and composition of stars in a galaxy reveal information about the galaxy's history, dynamics, and development.  Furthermore, stars are responsible for the production and dispersion of heavy elements such as carbon, nitrogen, and oxygen, and their properties are inextricably linked to the properties of the planetary systems that may form around them. As a result, the study of star birth, life, and death is essential to the field of astronomy. Formation of the Star Stars are born within dust clouds and are dispersed throughout most galaxies. The Orion Nebula is a well-known example of a dust cloud. Deep within these clouds, turbulence creates knots with enough mass that the gas and dust begin to collapse under their own gravitational attraction. The material at the centre of the

  Do you know about The first rain in our earth..?let's see.. First rain Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. For hundreds of millions of years, Earth was a burning furnace. The surface eventually cooled down and gases and water slowly trickled out from the mantle and erupted into the atmosphere as steam. One night — one of the short nights of that time which only lasted five hours — the first raindrop fell. Then came the flood. It probably rained for millions of years. Earth has shifted many times since then. There is not a fragment left from the oldest mountains, not a stone from the shores of the first shallow seas. The young solar system must have been a dangerous place for space travelers. Stone and gravel rumbled around in space like bullets over a battlefield. The sun did not shine as bright as today. If anyone still had their ways past, there was no place to land: Earth was burning, it had probably melted all t
