Volcanic fertilization of the oceans led to a severe mass extinction

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.

Seismic “telescope” reveals titanic tree-like plume fueling Earth’s volcanoes

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 […]

Secrets of Hot Spot Volcanoes Revealed • Earth.com

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 internal “magmatic filter” that causes the eruption of oceanic island volcanoes

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. […]

Mountains determine pace of evolution, not climate change, scientists say

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 […]

Volcanoes act as a safety valve for Earth’s long-term climate – Stabilizing surface temperatures

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.

Scientific guide to the mountains | Training, wildlife and higher peaks

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. […]

How are mountains formed?

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 […]

Cornish volcanoes that were active hundreds of millions of years ago

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, […]

Australia was once home to hundreds of ancient volcanoes. We can finally find out why

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 […]

How are mountains formed? – World Atlas

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 […]
