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.

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.

Continental Rifting, New Oceans, and Passive Continental Margins for Beginners
This video presents some basic information about how rifts form, how they sometimes evolve to become new oceans, and how passive continental margins form as a consequence.It has been adapted from a previous video entitled "Continental Rifting, New Oceans, and Passive Continental Margins: Plate Tectonics Basics 2", which was intended for an upper division geoscience audience. This video was made for a lower division geoscience and is intended to amplify undergraduate education of plate tectonic processes.

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.

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.

Naming Igneous Rocks
This video describes how hot magma is converted to igneous rocks, one of the three major groups of rocks on Earth. We explain how geologists use texture (grain size) to identify if the magma that formed the rocks cooled at Earth's surface or deep below ground. We then discuss how we can use simple observations of the color of the minerals in the rocks to further categorize them on the basis of their chemical composition (silica content). Finally, you will learn how to identify six common igneous rocks that represent a range of textures and compositions. You will have opportunities to practice identifying the essential characteristics of these rocks at several points during the video.

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.

Chemical Sedimentary Rocks
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 can be converted into a chemical sedimentary rock similar to those found in Petrified Forest National Park.

Streamflow
Rivers carved much of the landscape we inhabit, they deposited fertile sediment on the floodplains that we farm, and in many places their flowing water provides power to generate the electricity that lights our homes. This lesson takes a closer look at how water flows through stream systems from small creeks to large rivers. We explain what happens to the water in a stream channel as it travels down the length of a stream from its source to its mouth. We break down how to interpret a Hjulstrom diagram and take a Google Earth tour of the Mississippi River to investigate how discharge changes along its length.

Sedimentary Rocks
In this video we will classify the three major types of sedimentary rocks (clastic, chemical, biochemical) and give examples of each. You can learn how to casually drop terms like haboob, coccolithophore, and conglomerate into conversation. Finally, we explain how each type of sedimentary rock is formed and the settings where they could be found.
