Students will learn that the Lithospheric plates on the scales of continents and oceans constantly move at rates of centimeters per year in response to movements in the mantle. Major geological events, such as earthquakes, volcanic eruptions, and mountain building, result from these plate motions. Understand how convergent and divergent plates can produce volcanic activity at subductive plate boundaries and mid-oceanic ridges.

This video segment adapted from NOVA features the twisted and melted forms of the Grand Canyon's oldest rocks, the Vishnu Schist. These rocks, exposed only in the deepest part of the canyon, are the remains of mountains that may have rivaled the mighty Himalayas in height. The segment explains why metamorphic formations like these are so resistant to erosive forces.

This video is available in both English and Spanish audio, along with corresponding closed captions.

Discover why schist, a type of rock that underlies New York City's Manhattan borough, allows skyscrapers to soar, and learn why it’s present along the entire East Coast, in this video from NOVA: Making North America: Origins. Schist is composed largely of platy crystals. It is tough and solid enough to support the foundations of tall buildings. It starts out as mud that hardens under intense heat and pressure. The Manhattan schist layer comes near the surface in midtown and downtown, making these locations ideal for builders looking to attach skyscraper foundations firmly into bedrock. This resource is part of the NOVA: Making North America Collection.

The Grand Canyon: The Top Two Rock Layers

As you look at the sedimentary rocks at the Grand Canyon's rim, the top layers of visible rock are the youngest. In this video segment adapted from NOVA, a scientist explains what we know about the changing conditions in this location and the kinds of life they supported. The canyon's top layer, the Kaibab formation, records deposits laid down at the bottom of a shallow sea. The Coconino sandstone formation below it indicates that these watery conditions were preceded by much drier ones.

These writing prompts are tools for educators and students to use in the classroom to encourage creative writing. The topics covered in these clips are a variety of science related information bits that challenge a student to interpret what they see.

Nature | Florida's Spring

This video from Nature discusses Florida’s abundant springs and how they are shaped by the long journey of rainwater from the sky to the ground. Rainwater absorbs acids from plants and soil which dissolves limestone bedrock. This process allows cavities to form underground. The porous limestone acts as an underground purifier producing huge amounts of pure spring water suitable for drinking.

There's a story in every grain of sand: tales of life and death, fire and water. If you scooped up a handful of sand from every beach, you'd have a history of the world sifting through your fingers. From mountain boulders to the shells of tiny ocean creatures, follow the journey that sand takes through thousands of years across entire continents to wind up stuck between your toes.
