Scientists from the University of Southampton have found that two intense periods of volcanism triggered a period of global cooling and falling oxygen levels in the oceans, which caused one of the most severe mass extinctions in history. the history of the Earth. The researchers, together with colleagues from the University of Oldenburg, the University […]
The explosion of ocean life 2 billion years ago helped create Earth’s mountains: large amounts of plankton turned into lubricant after they died, allowing rocks to pile up on top of each other A dramatic increase in oxygen around the world 2.3 billion years ago led to an explosion of marine life like plankton There […]
This is the first in a series titled “Ancient Alabama,” examining the natural forces that have made Alabama what it is for the past 500 million years, and how these forces still shape it. State today. Each year, thousands of people visit Alabama’s Cheaha State Park to see the state’s tallest peak, climb the steps […]
Forest fires triggered by volcanic explosions ravaged Antarctica’s James Ross Island – once home to lush vegetation and dinosaurs – 75 million years ago, study finds Late Cretaceous fossil plants discovered in Antarctica Scientists analyzed the samples and found the charcoal characteristics This means that Antarctica experienced forest fires 75 million years ago. They were […]
The researchers observed for the first time the evolution of hot gas coming from an active black hole: they were able to observe these structures, strongly reminiscent of the smoke flows produced by volcanic eruptions with unprecedented precision and at a scale of hundred million time. year.

About 75% of the world’s volcanoes live along the aptly named Ring of Fire. It’s logic. Squeezing a boundary between tectonic plates, the Ring of Fire is an open seam within the planet. But then there’s Hawaii, a chain of volcanic islands right in the middle of the Pacific Plate, far from any border. What […]
The Sierra Nevada Mountains, sometimes referred to as the “Range of Light,†are one of the most beautiful continuous mountain ranges in the United States. Although the Rockies are the longest mountain range in the United States, the Sierra Nevada is the longest continuous, unified mountain range. The mountain range is located in the western […]

New research has yielded results that could potentially lead to the development of volcanic eruption warning systems. Previously, lava from “hotspot†volcanoes was thought to be virgin lava, coming from tens of kilometers deep in the mantle. This is not the case, explains Dr Teresa Ubide, a volcanologist at the University of Queensland. “It’s not […]
The volcanoes we see on the Earth’s surface are just the tip of the iceberg. Below the surface, they are fed by a complex network of conduits and reservoirs that bring molten rock, called magma, back to the surface. When the magma erupts, it can generate lava flows that cool down to become volcanic rocks. […]
Lava samples have revealed new truth about the geological makeup of the earth’s crust and may have implications for volcanic eruption early warning systems, a study led by the University of Queensland has found. UQ vulcanologist Dr Teresa Ubide said it was previously understood that the cooled lava from so-called “hot spot” volcanoes was “virgin” […]
Charles Darwin noted the evolutionary impact of geographic barriers when he observed the varying size and shape of finches on the Galapagos Islands. The physical barrier divides habitats and prevents animals from mixing and mating, which accelerates the evolution and emergence of new species. “Often on top of mountains there are many other unique species […]
Continental volcanic arcs such as this one in Kamchatka, Russia are rapidly weathered, leading to the removal of CO2 from the atmosphere over geologic time. Credit: Tom Gernon, University of Southampton Scientists from the University of Southampton have found that vast chains of volcanoes are responsible for both the emission and removal of atmospheric carbon […]

How are mountains formed? Most mountains owe their existence to the movement of tectonic plates, large sections of the earth’s crust. Where two tectonic plates converge, they warp and bend, resulting in the most common type: folded mountains. The Himalayas, for example, are the result of the slow collision of the Asian and Indian plates. […]

By Tran Hoa June 29, 2021 | 04:00 PT The central highlands province of Gia Lai is one of the few places in Vietnam where traces of centuries-old extinct volcanoes can still be found today. Chu Dang Ya is the name of a volcano that was active millions of years ago. In the language of […]

Mountains are landforms that rise above the surrounding terrain, usually thousands of feet high. Some mountains stand on their own; others are part of long chains called mountain ranges. Mountains are formed in one of three ways: Volcanic explosions Tectonic faults that occur when tectonic plates slide over each other Tectonic collisions The height of […]
You might find it hard to imagine, but Cornwall’s past includes barren deserts, terrifying prehistoric beasts, and volcanoes. Our county was once an active region of volcanism, and lava-spitting volcanic eruptions shaped the local landscape for millions of years to come. Although Britain’s last volcanoes are believed to have erupted around 60 million years ago, […]
Mountains have always played a central role in human culture, but it is only recently that we have understood how they form and develop. To this day, these magnificent reliefs still hold many secrets. There are several ways to analyze and classify mountains depending on your science discipline. Here we will describe in detail some […]
Geologically, Australia is a relatively quiet place to live. Earthquakes are rare and typically sweet, and as with volcanoes, there has not been as much as a burp of magma on the continent in thousands of years. It hasn’t always been that way. In fact, the earth is littered with the remains of mysterious eruptions […]
Australia’s east coast is littered with the remains of hundreds of volcanoes – the most recent only a few thousand years old – and scientists have been unable to explain why so many eruptions occurred in the 1980s. last million years. Today, geoscientists at the University of Sydney have discovered why part of a stable […]
The landscape of eastern Australia is dotted with hundreds of extinct volcanoes. They gave birth to an environment to which the Aborigines have been connected for tens of thousands of years, and to the rich soils upon which modern Australia has developed in recent years. a few hundred years.

Mountains are formed by movement within the earth’s crust. The crust itself is made up of several large plates, called tectonic plates, which float freely. These huge pieces of the earth’s crust move through molten rock called magma, allowing them to move and collide over time. Even though humans live on the crust, they don’t […]

Earth’s breathable atmosphere is essential for life, and a new study suggests the first oxygen burst was added by a series of volcanic eruptions caused by tectonics. The study by geoscientists at Rice University offers a new theory to help explain the appearance of significant concentrations of oxygen in the Earth’s atmosphere about 2.5 billion […]
A supervolcano is classified as a volcano with an eruption magnitude of 8, the largest Volcanic Explosivity Index (VEI) value where the volume of deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles) . Supervolcanoes occur when mantle magma rises in the crust and is unable to break through a fissure […]
Seeing the size and majesty of the mountains, the ancient humans couldn’t help but feel that they were standing in the presence of something… divine. And in the belief systems of many ancient cultures, it was generally held that mountains were something spiritual – serving either as a home for the gods, or as a […]
