Evolution of geological Earth now on your smartphone
Sydney: How did Madagascar once slot next to India? Where was Australia a billion years ago? To answer such questions, geologists here have developed a Cloud-based virtual globe which means anyone with a smartphone or laptop can visualise — with unprecedented speed and ease of use — how the Earth evolved geologically.
The globes have been gradually made available since September 2014. Some show the Earth as it is today while others allow reconstructions through ‘geological time’, going back to the planet’s origins.
Uniquely, the portal allows an interactive exploration of supercontinents.
It shows the breakup and dispersal of Pangea over the last 200 million years.
It also offers a visualisation of the supercontinent Rodinia which existed 1.1 billion years ago.
Rodinia gradually fragmented, with some continents colliding again more than 500 million years later to form Gondwanaland.
“Concepts like continental drift, first hypothesised by Alfred Wegener, more than a century ago, are now easily accessible to students and researchers around the world,” said professor of geophysics Dietmar Muller from University of Sydney.
“The portal is being used in high schools to visualise features of the Earth and explain how it has evolved through time,” he added in a paper appeared in the journal PLOS ONE.
The virtual globes includes visual depictions of a high-resolution global digital elevation model, the global gravity and magnetic field as well as seabed geology, making the amazing tapestry of deep ocean basins readily accessible.
The portal also portrays the dynamic nature of Earth’s surface topography through time.
It visualises the effect of surface tectonic plates acting like giant wobble boards as they interact with slow convection processes in the hot, toffee-like mantle beneath Earth’s crust.
“When continents move over hot, buoyant swells of the mantle they bob up occasionally causing mountains,” added professor Müller.
Conversely the Earth’s surface gets drawn down when approaching sinking huge masses of old, cold tectonic slabs sinking in the mantle, creating lowlands and depressions in the earth’s crust.
Since its inception the portal has been visited more than 300,000 times from more than 200 countries and territories. The interactive globes can be viewed on any browser at portal.gplates.org.
“These cloud-based globes offer many future opportunities for providing on-the-fly big data analytics, transforming the way big data can be visualised and analysed by end users,” noted professor Müller.
Lucknow: Vishal Singh, a renowned social worker from Lucknow, also known as Foodman, has once again made India proud. He was honored by the Happy Hands Gloves Cooperative Limited Company in Korathai, Thailand, for his work with the Hunger Free World Mission.
The Hunger Free World Mission’s meeting was held in Korathai, Thailand, under Vishal Singh’s leadership. Representatives from several countries, including Mr. Raja Dwivedi (Managing Director of Happy Hands Gloves Limited), Thailand Coordinator Mr. Raja Mishra, and member Mr. Varun Singh, attended the event.
Under Vishal Singh’s leadership, the attendees took a pledge to work together toward creating a hunger-free world.
Speaking on the occasion, Vishal Singh explained that the main goal of the Hunger Free World Mission is social participation. He said the mission is not just about feeding people but also about meeting other basic needs of those who are struggling. The mission focuses on helping families of terminally ill patients in hospitals by providing food and shelter. It also works to fulfill essential needs like education, jobs, and care for the elderly.
For the last 16 years, the Vijay Sri Foundation has been providing free services, benefiting thousands of people. Vishal Singh highlighted that the mission aims to gain global recognition like other organizations such as WHO, WWF, and Red Cross, which work for social causes.
During this meeting, Vishal Singh was appointed as the Chairman of the Hunger Free World Mission by representatives from various countries. They also discussed holding regular meetings in different countries to push the mission forward.
Business tycoon Dr. Abhishek Verma has also supported this humanitarian mission, vowing to promote the idea of “Seva Parmo Dharma” (Service is the highest duty) worldwide. Vishal Singh praised him, stating that people like Dr .Abhishek Verma inspire others to work for the betterment of society.
Recently, Romania’s Ambassador, Mr . Daniela Sezonov Ţane, invited Vishal Singh to the Romanian Embassy in Delhi, where they discussed the mission in detail. Impressed by his humanitarian work, she honored Vishal Singh and invited him to Romania to take the mission forward .
Food man Vishal Singh has been serving the people of India for the past 16 years. Through the Vijay Sri Foundation, he provides free meals to cancer patients & their families ,shelter, and education for women & children along with running free old-age homes in Lucknow.
In addition to his humanitarian work, Vishal Singh also addresses issues like crime and corruption through his role as Chairman of Seva Path Media and Managing Director of Vijay Sri Foundation.
During the COVID-19 pandemic, Vishal Singh and his team worked tirelessly to provide food and help to the needy, including starving children, elderly citizens, and pregnant women. Despite contracting the virus himself, he continued to assist others after his recovery. He even created a life-saving oxygen regulator using household items, which was praised by doctors both in India and abroad.
In his address at the meeting, Vishal Singh spoke about his mission to create a hunger-free world. He pointed out that India’s large population, along with issues like unemployment and poverty, has caused the country to fall on the Hunger Index. He urged people to contribute just one handful of grains daily to help create a hunger-free world.
He concluded by saying that through social participation, we can empower the people around us, meet their basic needs, and work together to build a stronger, more prosperous, and developed society.
