Ancient rocks have revealed how volcanoes unleashed the mass extinction that affected the dinosaurs. Volcanoes, once thought to be a safe place for animals to live, have been linked to the rise of millions of killer hurricanes as well as a string of other natural disasters over the past century. The ancient rocks tell us that after a massive volcanic eruption, layers of volcanic ash and lava were deposited in the oceans around the world. When these massive amounts of ash and lava entered the ocean, they mixed with water and chemicals from the ocean’s depths and caused extremely heavy storms.
This mixture was picked up by the wind, carried away by the currents, and dumped on land where it darkened the land and turned the once green landscape into a dead zone known as a black forest.
When the giant volcanic eruptions occurred, the animals that lived in the rock layers were wiped out. Over the last century and a half, we’ve only seen remnants of these ancient animals in museums, thanks to careful analysis of fossilized animal bones from amber and sea shells. The same thing happened to the earth’s climate, with catastrophic volcanic eruptions washing away much of the ice and snow that kept the planet’s temperature stable. The greenhouse gases that resulted from this runaway process set off a chain reaction, accelerating the earth’s temperatures to what is considered a paleo-melt, one of the largest geological shifts ever recorded.
As this earth-shaking event unfolded, the animals that lived alongside plants began to die off. This marked the start of the next phase in Earth’s history known as the “Canyon Formation”. The animals emerged from their hiding places to face the new climate. The ecosystem they once enjoyed was gone, and their numbers declined drastically. This is how volcanoes unleash the mother of all mass-extinction events. They send a powerful message to the world by letting us know that something awful is going to happen to our world if we don’t change our habits.
When looking at the composition of these ancient rocks, you can see evidence of multiple explosions. The fact that there are many different types of rock scattered around the globe demonstrates that there was a great volcanic eruption not too long ago. We can also see that there has been a consistent pattern in eruptions; there is a peak followed by a period of relatively low activity. This type of repetitive behavior is what we would expect to find if volcanic activity was responsible for the mass extinction that killed off the dinosaurs.
The lava that erupts from these volcanoes also provides us with another piece of the puzzle. Lava travels at a very fast rate. This means that once it forms, it must quickly travel up to hundreds of meters through the air and onto the ground. The speed at which lava travels is similar to that of a rocket traveling to the moon. Therefore, if the volcano has an active interior, it’s possible to see how eruptive events may have wiped out some of the different layers of the earth’s surface in the past.
Finally, an ancient rock show us how volcanoes unleash the mother of all extinctions by telling us that these events took place billions of years ago in the distant past. The type of rock that these eruptions produced are similar to those produced today by erupting volcanoes. Furthermore, the intensity and longevity of these events provide further clues as to why these eruptions may have occurred. The fact that these eruptions took place in the distant past supports the idea that the Earth has experienced multiple explosions in its history. This theory may explain why there is still so much radiation around the Earth from these ancient volcanic explosions.
Overall, ancient rocks can be a valuable way to learn about the past. They provide evidence for the fact that certain volcanic eruptions may have actually been bigger than we think. They also show us how volcanoes unleash the mother of all extinctions.
These points all boil down to one fact – volcanoes to erupt. Therefore, learning more about our planet’s history and what kind of eruptions took place will help us better understand our place in the grand scheme of things. This knowledge could help us design an overall plan for preventing future eruptions from taking place. While an ancient rock may not be able to tell us everything, using other types of ancient rocks like lava beds, ocean stones, and sulfur clays can help us learn more about the volcano sciences.
