Ask-a-Geologist #1: How Much Chemistry is Involved in Geology?

hi everyone I'm Tracy Barnhart the professional geologist here at mini-me geology every week we get great questions on our website about book study and science of geology in this new series we're going to answer your questions in video to give you more in depth answers to keep this questions coming in today's question is about chemistry and geology today's question is from Alexandre and she writes how much chemistry is really involved in geology I'm not that great at chemistry but I really am interested in geology hi there Alexandre well there is a fair amount of chemistry […]

Red Dead Redemption 2 – All 10 Secret Rock Carving Locations! (Geology for Beginners Missions)

What's up guys and welcome to another video. Today's video I will show you all 10 locations for the rock carvings if you're gonna go and do the side mission of "Geology for Beginners". if you have started this side mission already I highly recommend it. For a side mission it is very very weird when looking at it from a story perspective. I think this whole side mission could be implemented in a way to do a Easter Egg it might even be a step, so I highly recommend doing it. If you haven't seen it already take a […]

The Trouble With Trilobites

They're probably the most recognizable fossils in the world. Flat segmented bodies bristling with antennae and legs. They're what we think of when we think of life in the ancient sea. But trilobites are famous not just because they were so beautifully functional or because they happened to preserve so well. They're known the world over because they were everywhere. For more than 270 million years trilobites thrived all over the planet, scouring the ocean floor from Siberia to Morocco and Canada to Australia. In their time they were the planet's most successful and possibly its most abundant animal until […]

Physical Geology – Deltas – Part 2

>>Dr. Doug Elmore: Take a look at this map of the Mississippi Delta. Note that there's a much shorter path from this point on the map to the Gulf of Mexico than the current Mississippi path. In fact, it's about 190 miles shorter. The current Mississippi Delta has built out so far into the Gulf that the river has been attempting to change its course for some time and flow down what is called the Atchafalaya River, the shorter path to the Gulf. In a location called Old River Control, where the U.S. government tries to keep the Mississippi in […]

California Earthquakes with Geology Professor Steven Dunn | Connecting Point | July 24, 2019

>>> EARLIER THIS MONTH, CALIFORNIA WAS ROCKED BY A POWERFUL EARTHQUAKE THAT MEASURED MAGNITUDE 7.1, THE BIGGEST QUAKE TO HIT THE STATE IN 20 YEARS. IT'S SUBSEQUENTLY EXPERIENCED FURTHER QUAKES AND SHOCKS IN THE AFTERMATH. WHY THE HIGH LEVEL OF ACTIVITY RECENTLY, AND WHAT'S THE HISTORY OF EARTHQUAKE ACTIVITY IN THIS REGION? I SAT DOWN WITH STEVEN DUNN, A PROFESSOR AT HOLYOKE COLLEGE FOR ANSWERS. >> WHAT THEY ARE HAVING IS NORMAL IN A LONG TIME SPAN OF WHAT'S TYPICAL. THE RIDGECREST EARTHQUAKES ARE NOTABLE IN A FEW REGARDS. THEY ARE A LITTLE ACTIVE FAULT ZONE NEAR THE MOJAVE, AND […]

Iowa Landforms | Iowa Land and Sky

I was divided into seven mainland form regions each land form has sort of a unique geologic history that that shapes the way it looks the Des Moines lobe in the north central part of the state on the northwest Iowa plains Lost Hills region in western Iowa southern Iowa Jeff plane is central third of the state and then Iowans surface is northeast Iowa and then what we call our alluvial plain so that's one of the areas connected to the Mississippian that's river valleys then the last region is the Paleozoic flat tail you know you can get […]

When a River Goes Missing, It’s Kind of a Big Deal…

Geoscientists spend their lives studying features in nature that move very, very slowly. Glacial melt, plate tectonics, things like these take their sweet time to develop. So, when an entire river vanishes in just four days, it’s safe to assume geoscientists are going to freak out. A paper recently published in Nature called this very sudden disappearing act “river piracy.” Sadly, there were no actual pirates involved in the making of this study … but river piracy, or it’s less exciting name, “stream capture”, is a geomorphic phenomenon where one river captures and redirects the flow of another. In 2015, […]

Physical Geology – Minerals – What are Minerals and Their Properties?

>>In this video we will discuss the properties of minerals. One of the most important properties is the hardness of the mineral. The hardness of the mineral is based on the strength of the bonds that occur in the mineral, and the way we think of hardness is we have a scale. It's called Mohs hardness scale, and it goes from 1 to 10. As a point of reference, a knife, some metal, has a hardness of 5. The mineral gypsum–this is a piece of gypsum right here–has a hardness of 2, and I can scratch it with my fingernail. […]
