Man-made Disasters

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 and its Types,with example

-
Image
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

Lunar eclipse and difference between Solar eclipse and Lunar eclipse?

-
Image
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...and its types?

Image
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

Black hole-Causes,size etc..

-
Image
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 Ozone layer...? And why it is important?

-
Image
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?

-
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
