GeoScience Videos
Приєднався 15 жов 2014
These videos describe content featured in college-level introductory geoscience courses but may also be applicable to other disciplines and to high school curricula. Most videos are approximately 6 minutes long but we have recently started posting shorter, minivideos that deal with a single concept. We use the longer videos as part of our flipped-class teaching model and the shorter videos as learning supplements. We would love to learn about how you are using them. Consider visiting our related blog (geosciencevideos.wordpress.com) for quizzes associated with content from the longer videos and other resources.
Measuring Earthquakes
This video explains the difference between two measures of earthquake size as represented by earthquake magnitude and earthquake intensity. We discuss why the fabled Richter scale no longer is effective in accounting for large earthquakes; we consider how fault length is related to earthquake magnitude and whether it is possible to get a future magnitude 10 earthquake; and, we discuss how everyday folks can apply the intensity scale to assess earthquake damages around them.

Why is That There? (Plate tectonics has some explaining to do)
Переглядів 6 тис.3 роки тому
This video examines the major features on Earth’s surface relative to the distribution of important earth processes. Any conceptual model of how Earth works, like plate tectonics, must be able to explain these patterns.
How to Melt Rocks
Переглядів 22 тис.3 роки тому
This video will explain how rocks melt to produce magma in a variety of plate tectonic settings. We explain the processes behind decompression melting, flux melting and heat transfer melting.
Partial Melting of Igneous Rocks
Переглядів 22 тис.3 роки тому
This video describes how igneous rocks form in different plate tectonic settings (oceanic ridge, hot spot, volcanic arc) as a result of partial melting and other processes. We identify which volcanic and plutonic igneous rocks would form at each plate location.
A Beginner's Guide to Creating Short Instructional Videos
Переглядів 3,3 тис.4 роки тому
A few years ago, we began creating short instructional videos for an introductory geology course. While we had little prior experience in making videos, previous research provided us with some principles for effective multimedia design. Based on our experiences, we offer some suggestions for instructors who are considering creating their own short videos. We provide guidance on research-based d...

Jason and David welcome viewers to the channel. Check out our short (~6 minute) videos on a variety of basic geoscience topics or sample some minivideos that zero in on a specific idea.
Continental Drift
Переглядів 64 тис.6 років тому
This video describes the evidence Alfred Wegener used to formulate his continental drift hypothesis and examines why this idea did not gain wide acceptance when it was originally proposed. Wegener pursued four lines of evidence to support continental drift and the existence of the supercontinent, Pangaea. His evidence included the fit of the continents, matching features between now separated l...
The Earth System
Переглядів 182 тис.6 років тому
This video describes the four main components of the Earth system (atmosphere, biosphere, geosphere, hydrosphere), how matter is exchanged between the components, and how a change in some aspect of one part of the system will result in changes in other system components. We describe the Earth system in terms of reservoirs and flux between them and discuss how the movement of carbon occurs betwe...

8 Reasons for Complex Life on Earth
Переглядів 9 тис.6 років тому
This video describes an array of circumstances that make it possible for complex beings like us to live on Earth. While some of the reasons for life on Earth may be obvious, others are surprising. All of these natural factors line up just right to put our planet in the appropriate location, generate a diversity of physical environments, and provide the mix of air and water we need for survival....
Glacial Landforms
Переглядів 125 тис.7 років тому
In this video we review the principal landforms created by glacial erosion (cirques, arêtes, striations, U-shaped valleys, fjords) and deposition (till, moraine, drumlins, eskers, kettle lakes, outwash plain, erratics). We discuss how a pair of glacial erosion processes - plucking, abrasion - work to break down rocks and modify the landscape. We compare and contrast glacial deposits made up of ...
Classifying Glaciers
Переглядів 33 тис.7 років тому
This video reviews the features of the two major types of glaciers - ice sheets and alpine glaciers. We explain the conditions necessary for the formation of glaciers and describe the features of both ice sheets (massive, thick contain very old ice, form in polar regions) and alpine glaciers (smaller, younger ice, found in mountains). You will learn that glaciers in specific locations may have ...
What is an Aquifer?
Переглядів 375 тис.7 років тому
This video describes the basic characteristics of two types of aquifers and identifies four types of geological units that make up many of the aquifers in the US. We compare and contrast unconfined and confined aquifers and show the distribution of aquifer systems composed of sand and gravel, sandstone, carbonates (limestone), and fractured igneous and metamorphic rocks. On the basis of the map...
Chemical Sedimentary Rocks
Переглядів 59 тис.8 років тому
This video describes how various types of chemical sedimentary rocks form. We start by heating up some water in a pan to show you an analog for the formation of natural salt deposits. We discuss how small changes in water chemistry can result in spectacular rock formations like stalactites in limestone caves and travertine terraces associated with hot springs. Finally, we talk about how wood ca...
Biochemical Sedimentary Rocks
Переглядів 25 тис.8 років тому
This mini-video describes how biochemical sedimentary rocks are formed by the actions of organisms or as these organisms die and collect on the sea floor. We discuss how shellfish get their shells, what a coccolithophore is and how it takes billions of them to form the iconic chalk cliffs along the English channel, and how million year old trees went to make up the coal we burn today to generat...

hey, my college is supposed to pay people for videos like these but they are using your video and I'm assuming without your permission, It is called Wake Technical Community College, just wanted to let you know

Awesome 💯🔥❤️
watching it from India ... nice explanation and illustration , but u must add the overall word data along with your country's
hi
thanks for this video! such a great explanation :)
Hi all. Breathe air. God made everything. His son, Jesus, pardoned all of all wrongs.
I can do All of this
Great educational video here, very understandable and logical. a bit old fashioned, but that 90s nostalgia is OK with me :P
I just started taking a geology course above my skill level 😅 and this video is super helpful 😁👍
2024❤🎉🎉
I don't usually stop learning to thank people for their content, but this is the best explanation for faults that I have seen yet! Wonderful teaching style and great video!
Format is hard to stay focused with but the structure of how the information is presented is beau. Very accessible.
1) Define the term "dip". The term dip refers to the slope or inclination of any geological surface measured relative to horizontal 2) A strike line is a line that is horizontal Line drawn or inscribed on a sloping surface 3) Dip and Strike are how many degrees from each other 90 4 The block above the fault surface is called the hanging wall 5) The block below the fault surface is called the Foot wall 6) A normal fault occurs when the hanging wall moves down 7) A reverse fault occurs when the hanging wall moves up 8) A normal fault occurs along what plate boundary divergent 9) A reverse fault occurs along what plate boundary convergent 10) Strike slip faults occur along what plate boundary transform
Very informative educational presentation - thank you!!

Thank for this info,but i have question ,adrilling ground water has 345m and it has ignibrite and bazalt formation so how to calculate well logging of blind casing and screen casing after finishing?
Very helpful video Thanks
Thank you for all your effort! It is truly useful!
This was easy to understand 👍🏼
🤨🤨🙄🙄🤕🤕🤯🤯😤
this was sooo helpful!! thank you so much for making this video!
You forgot the Jaun de fuca plate subducting in the Pacific Northwest
I watched this a few months ago and I still was thinking about it, idk but their form of explaining and the examples were so useful...
The planet gets greener as the carbon levels increase, nature already has an adaptable system to address carbon fluctuations. As we have seen in the planet greening in recent decades. Plastics and radioactive waste are the real pollution problems. Carbon is not an issue.
Great username!
Super explanation. Cleary understood. Thank you.
Thank you 🙏
not me not understanding most of this💀
i can do all of this
very informative
Thank you
Being 80 and living in the adirondack mountains and found 3 Rhyolite volcanos with no place higher from here to hudson bay and this is in yellow stone national park. If you are not a geologist you will figure it out. I found the volcanos because of my forestry training and to find gold. Red pine trees and schoch pine trees are not native to the U.S. the CCC camp planted tree in the adirondacks for 8 years to see some thing different on a you tube channel watch century new technologies company inc start at the third from the last movie to where mother nature plugged up plum brook

What? 😂 I woke up, and this was the video playing. #SleepyGang
Basically a sponge
Nice, thanks. Just been to St Davids, Pembrokeshire, Wales, and there are lots of faults - mainly Geological :) :) NOw I can start to identify some....
Thank you this is help to me
this video rocks
what do u write for “visible minerals”??
I was not prepared to witness that hyper-realistic depiction of an Earthquake.
Not a math genius or anything by far, but I am pretty sure "1750 million years" should have been 1.75 billion years instead. I have to use this video for my geology class and between the switching of narrators and play-dough models, I am more confused than reading it in the book.

So Simple! Thank you for making this easy to understand.
This is great! It so crazy that we exist at all, for all of these features to go right and allow life on earth. It makes me feel hopeful about the future, honestly. The forces that kept life going long before us will continue long after we are gone and life will arise again.
The water/milkshake demonstration is fantastic! Great video!
I am interested in the Karoo Ice Age. Are there still traces of it?
i love this channel im subbing
