The Ring of Fire

 Have you ever seen an active volcano? Do you know that there are more than 1,500 volcanoes that are active today? yes, you've read the line correctly and an estimated 500 million people live near these active volcanoes.



Today I would like to share some knowledge about one of the dangerous things on this planet The Ring of Fire.

The Ring of Fire is also known as the Circum-Pacific Belt. It is a long path along the pacific ocean surrounded by active volcanoes. Earthquakes occur very often in these areas. Approximately 75% of the world’s volcanoes occur within the Ring of Fire. It encircles many tectonic plates such as the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates. It is 40,000-km (24,900-mile) in length.




The number of volcanoes and earthquakes is caused by the movement of tectonic plates. These areas are mostly bounded by volcanoes thus this region is called "The Ring of Fire".

Major volcanic events that have occurred within the Ring of Fire are

  • Mount Tambura (1815)
  • Krakatoa (1883)
  • Mount Saint Helens (1980)
  • Mount Pinatubo(1991)

Major Earthquake events

  • Chile earthquake(1960)
  • Alaska earthquake(1964)
  • Chile earthquake(2010)
  • Japan earthquake(2011)


Main causes of Volcanic eruptions:

  • When magma rises to the surface.
  • When there is a high pressure from dissolved gases in magma.
  • When the mantle melts to form magma ,and increases the amount of magma present.

On average, there are about 50-70 volcanoes that erupt every year. When a volcano erupts they spew hot, dangerous gas, ash and lava that can cause loss of life and property. These eruptions affected 6.2 million people and caused nearly 2400 deaths between 1998-2017

Why Pluto is not considered a planet ??

Image
  H ave you ever thought about why Pluto is not considered a planet? Now have a random think why? I'm sure you would want to know why      Because it doesn't satisfy the three criteria of a planet. they are        1. It is in orbit around the Sun.       2. It has sufficient mass to assume hydrostatic equilibrium (a nearly round in shape)      3. It has cleared the neighborhood around its orbit. Pluto meets only two of these criteria, losing out on the third. Now you may wonder what is clearing its the neighborhood? It means that using its gravity a planet must remove asteroids, dwarf planets out of its path. Now Pluto is in orbit around the sun, has a spherical shape, but has not cleared its path. Thus Pluto is considered a dwarf planet. What is a Dwarf planet ? Dwarf planet, a body   that orbits the Sun  and that is, for practical purposes, smaller than the planet Mercury  yet large eno...

History of Chocolates

  T he only thing loved by everyone in this world despite their age is chocolates. Nearly 90% of the world's population loves chocolate. Numerous people around you including you may love chocolates like me. But have you ever thought about where the chocolate came from? Who invented it? So, now we'll look in the history of chocolate Where was it's origin? It's hard to pin down exactly when chocolate was born, but it's clear that it was cherished from the start. Chocolate's rich history of 4.000 years began in Mesoamerica (present-day Mexico). Olmec is one of the earliest civilizations in Latin America, were the first to turn the cacao plant into chocolate. They drank their chocolate during rituals and used it as medicine.  Today, such drinks are also known as "Chilate" and are made by locals in the south of Mexico and the northern triangle of Central America (El Salvador, Guatemala, and Honduras). Later, the Mayans praised chocolate as the drink of the ...

Perspective : Don't let it cloud your judgement

“Our environment, the world in which we live and work, is a mirror of our attitudes and expectations.” — Earl Nightingale Greetings         Here I am, Shaik Vizdania with an convoluted yet intriguing topic- Perspective  Ernest Holmes, an American writer once said   “Life is a mirror and will reflect back to the thinker what he thinks into it.”    What do you think he means ?  He is emphasizing the importance of your point of view.  It is his desire to convey that our views reflect who we truly are . Let me give you a few examples    Empress Wu Zetian , the first and the only emperor of China . She was the empress of Tang dynasty of China which she ruled for over 15 years. She rose from a lowly concubine of Emperor Taizong of Tang China to the Empress of the majestic China. And also she is one of the most misunderstood leader. The Chinese history has portrayed her as an evil and a vicious woman who stole the throne a...
