A Brief Introduction to Minerals

Hi, everyone in this video. We’re going to be talking about Minerals, so let’s get started What are minerals anyway well in the simplest sense of the term minerals are the building blocks of rocks? Here’s a rock. This is a piece of the igneous rock called granite if you look carefully at this chunk of granite You’ll see all sorts of speckles of Gray and white and black and if you in You’ll see that these are crystals mineral crystals this particular piece granite has the mineral quartz Biotite Mica and Plagioclase feldspar We’ll study these more detail later […]

18. Major Events in the Geological Theatre

Now today we’re going to be talking about some of the major events in the geological theater this is the second of three ways that we’re looking at the history of life the first was rather abstract it had to do with major transitions and with reorganization of genetic information units of selection things like that that was last time today we’re going to talk about how life shaped the planet and how the planet shaped life so this is a quick run-through of 4.5 billion year process and then next time we’re going to talk about major lessons from […]

Scientists in the Wild: Dr. Julie Libarkin, Geologist

Oh, that’s a good question. So I’m a geologist and for many years I studied mountains and high plateaus like the Tibetan Plateau or the Colorado Plateau and how they formed. And now I study what I call Geocognition which is the intersection between cognitive science, how the brain works, and geological sciences. So really how people perceive, understand and interact with the planet. So a geologist is someone who studies the earth. And you can actually think a little more broadly about an earth scientist. So a geologist would be someone who studies the solid earth. Sort of the […]

Geology of Ohio: Episode Two – Caesars Creek

To start off on this topic I’ll give some background information about this National Park located about five miles east of waynesville Ohio Caesars Creek came into being in 1971 when the Army Corps of Engineers erected a dam to control flooding in the valley the emergency overflow control spillway is where much of the geology of CJ’s Creek can be found the channel exposes prime 445 million year old order vision outcrop with an abundance of fossils but we don’t need again to that just yet first let’s look into the depositional environment and the time of the order […]

How Auckland Volcanoes Erupt

Auckland City is built on a field of small volcanoes, about 50 of them. And some of these volcanoes you can see as you drive around the city – they’re obvious cones. other volcanoes are really just holes in the ground, and that tells us about the different styles of eruption that have taken place in Auckland during the past quarter of a million years. Beneath Auckland there is a hot-spot in the mantle, we think at a depth of about 80 to 100 kms and in this hot-spot rocks are melting and producing magma. The magma segregates and it […]

Can Goats Predict Volcanic Eruptions?

The Argentata dell Etna is a breed of goat found nowhere else in the world. Each morning, Gaitano herds his animals out onto the slopes of the volcano. The goats will eat just about anything. But Gaitano knows that on the upper slopes of Etna, there are glades of a yellow flower that he thinks gives his goats milk a unique taste. Gaitano has been working on the mountain his whole life, and in that time, he’s noticed some bizarre behavior in his animals. He believes that the goats behave erratically, not just during one of Etna’s eruptions, but before […]

Using the Earth as Inspiration: Learning Geology at Valles Caldera

There is simply just so much a person can understand, so when you get a number of one-of-a-kind groups collectively, that is the place you really start to gain knowledge of new things. And the scientists that have been around us from the State of Mexico, and across the entire United States of America as good, has been instructing these kids on how do their work. They were opening their eyes into how much geology is around them and how much they rely on it for their every day lives. These kids were hungry for training. They had been in the […]
