Video Catalog

This video reference collection was begun as part of the 2014 virtual workshop on Designing and Using Videos in Undergraduate Geoscience Education. The purpose of the catalog is to pull together links to resources from all over the web; we are not hosting videos here. If you have a favorite educational video you made or use, and you'd be willing to share the link, please tell us about it!

Interested in learning how to make a video of your own? Check out our collection of how-to video tutorials.

What are Volcanic Hazards?
In this video we will describe the most common types of volcanic hazards associated with a volcanic eruption. We begin by considering the threat of an eruption from a Cascade Range volcano for citizens of Portland and Seattle. These are examples of composite volcanoes. Eruptions of these types of volcanoes produce tephra, lahars, pyroclastic flows and lava. Tephra represents the debris blasted into the air and can range in size from tiny glass shards to large blocks blasted out of the volcanic cone. When tephra combines with water it forms lahars that can transport all sizes of debris. Fast moving, toxic pyroclastic flows are among the most dangerous volcanic hazards. Lava plays a relatively modest role in eruptions of composite volcanoes but is a common product of shield volcanoes such as those in Hawaii.

Transform Plate Boundaries
This video discusses the characteristics of transform plate boundaries where plates slide past each other. We examine four examples of transform boundaries between plates and describe how and why short transform segments offset the oceanic ridge system throughout the world's oceans. We take a closer look at the major transform boundary in North America, the San Andreas fault system and examine what the plate boundary looks like in the Californian desert and what might happen if it were to slip like it has done in the historical past. Finally, we give you an opportunity to see if you can identify the location of a transform boundary where it cuts across part of New Zealand.

Tsunami Caught on Camera
A British Documentary on the Boxing Day Tsunami that hit Asia in 2004

The Geological History of Earth
This video discusses the major changes to the planet since its formation to the present day. We explain how Earth formed, where the Moon came from, how the atmosphere changed over time, where the water in the oceans originated, what the first life and fossils looked like, when more complex life forms began, a long period when little happened, when most of Earth became a snowball, and how extinction events allowed geologists to break down the most recent chunk of geologic time. You will learn the difference between an eon and an era, why we should be grateful for asteroid and comet impacts, and when oxygen started showing up in the atmosphere.

How to Classify Volcanoes
This video describes the features geologists use to classify common types of volcanoes. We compare and contrast the features of two types of large volcanoes - shield volcanoes and composite volcanoes. One of these types produces structures that can be larger than Mount Everest while the other represent the majority of dangerous active volcanoes on Earth.We also explain that two other types of smaller volcanic landforms are relatively common and often form in association with their larger brethren. Finally, you can take a simple volcano recognition quiz to try to classify five examples of US volcanoes.

Earth's Elements and an Introduction to the Silicate minerals
This video identifies how rocks are composed of elements that build minerals. We identify the most common elements in the crust, as well as in the whole Earth. Viewers will recognize common elements from their breakfast cereal that are also key components in the rocks below our feet. We will learn that only a handful of elements combine with silicon and oxygen to form the silicates, the world's most abundant group of minerals. Finally, we describe the characteristics of silicate minerals, and how they break down to form simple commodities like sand and gravel deposits.

Glacial Landforms
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 an unsorted mix of clay, sand and boulders and those that have been generated by running water. Finally, we start and finish the video by trying to figure out how a giant boulder ended up jammed in among the trees in Yellowstone National Park. The video ends with a short review quiz that asks you to identify four images of different landforms.

Metamorphic Rocks (& toast)
This video discusses the formation of metamorphic rocks, one of the three major groups of rocks on Earth and the bedrock under much of North America. We explain that toast is a metamorphic form of bread and describe the conditions necessary for metamorphism to occur (burial of rocks, proximity to magma, plate tectonic settings). You will learn about the metamorphic temperature window, how developing a foliation is similar to squeezing a marshmallow, the names of some common metamorphic rocks, and what happens when sandstone and limestone are subjected to higher temperatures and pressures.

Classification of Faults
In this video we introduce viewers to two terms they will need to understand to classify faults. We define the terms strike and dip in relation of everyday inclined surfaces including sloping brick surfaces and dumpster panels. Next we introduce you to the hanging wall and footwall of faults and provide a brief assessment to allow you to practice using the terms. We apply all four of these new terms to classify dip-slip and strike-slip faults. We end by shaking up a Lego geologist during fault movement and by asking you to interpret three examples of strike-slip faults.

The Formation of Clastic Sedimentary Rocks
In this minivideo we will discuss the three steps in the formation of clastic sedimentary rocks - weathering, transportation, and lithification.
