Shows how gravity affects erosion. Documents how scientists study erosion and weathering. Highlights the California landslide problem. Surveys the destruction caused by fast erosion. Explains why deforestation and building houses and other structures contribute to erosion.

Everyday, real-life examples demonstrate the processes of weathering and erosion. Easy-to-understand examples of weathering help students differentiate between the processes of mechanical and chemical weathering. Footage of weathering and erosion processes help students grasp how each process alters the environment. Important terminology includes: mechanical weathering, landslides, abrasion, freezing, thawing, chemical weathering, oxidation, acid rain, moving water, wind, and glaciers.
Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion and the effect of gravity on objects is discussed in this video. Other topics covered include folding, faulting, deposition, creep, mass movement, landslide, surface runoff, alluvial fan, delta, stream erosion, beach erosion, ice erosion, wind erosion, dune, glaciers, and glacial deposits.
The residents of Block Island fight to save a sea side lighthouse from beach erosion. They join together and hire a team of brothers to move the lighthouse back from the cliffs. The 2,000 ton structure is moved 300 feet in an effort to save it from the ongoing erosion of the bluffs along the coast of Rhode Island.
Oyster reefs protect shorelines from erosion, create fish habitats, and clean the water. Scientists in North Carolina are working to restore the oyster reefs along the coast.
Learn the differences between sedimentary, metamorphic, and igneous rocks.
Surveys soil's formation, composition, properties, types, and movement. Also identifies the five major plant communities: tundra, forests, scrublands, grasslands, and deserts. The connection between soils and vegetation affects where people live.
Tour three Martian landscapes and find out how erosion and water has affected the surface of Mars. Flyover images show the structure and composition of the landscape of Mars and focus on Candor Chasma, part of a canyon system of Mars.
While it may not always seem possible, Earth is continually changing. Students gain insight into geological processes such as the formation of land, erosion, and volcanic eruptions. Other Earth processes are also investigated.
The Earth has many land formations such as mountains, plateaus, hills, and plains. These formations are created by movement of the earth’s plates, volcanoes, weather, and erosion. Part of the Real World Science series.
The importance of forests cannot be underestimated. Humans depend on forests for survival, from the air they breathe to the wood they use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion, and mitigate climate change.
In this segment, students learn about the process of weathering. It is the breaking down of rocks, soil, and minerals through contact with the earth's atmosphere, water, and biological organisms. Other topics covered include erosion, surface water, groundwater, wind, and waves. Part of the "Earth Science" series.
In response to one of the worst wildfires in Colorado history, scientists from Warner College at Colorado State University are leading a large-scale wildfire impact study. The study will provide critical data to communities still grappling with the destruction caused by wildfires. Some issues they will study include water quality, erosion, and ecosystem restoration.
Animal researchers travel to Easter Island, one of the most remote inhabited islands on Earth, where a mystery illness is plaguing horses. A chance encounter by a veterinary pathologist reveals a disturbing fact: an invasive, non-native plant introduced to prevent soil erosion is poisoning the horses. Segment of video from Wild Chronicles Series.
This episode highlights recent studies related to beaches and marine life. Researchers have found that seagrass has a strong potential for curbing erosion. Other features include the impact of climate change on right whale movement, expanding efforts to save coral reefs, and the dangers of hurricane storm surge. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
As shown on the History Channel. It is the tallest and biggest mountain on Earth, as far removed from sea level as it's possible to be--and yet its sedimentary layers contain fossils that were once creatures that lived on the ocean seabed. The Himalayas formed when India smashed into Asia--propelled by plate tectonics. Everest is still rising but its height is limited--extreme erosion counteracts and limits the amount of uplift.
The geology of the Great Plains is a product of long periods of sedimentary buildup followed by equally long periods of erosion. The result today is a dramatic landscape of bluffs, pinnacles and badlands that contain the rich story, of ancient sea creatures, dinosaurs and long extinct, giant land mammals. The Agate Fossil Beds is a landscape that reflects many influences from early animals roaming the valleys and hills to tribal nations they call the High Plains home. Explorers passing through or settling the American West also have a part in the story.
Everywhere one looks in Southern Louisiana there's water: rivers, bayous, swamps, the Mississippi River, and the Gulf of Mexico. And everyone in Cajun Country has a water story, or two or three or more. Its waterways support the biggest economies in Louisiana - a $70 billion a year oil and gas industry, a $2.4 billion a year fishing business, tourism and recreational sports. But these waterways are also home to some insidious polluters along a 100-mile-long stretch of the Mississippi known "Cancer Alley," the world's largest Dead Zone in the Gulf of Mexico and erosion that is costing the coastline twenty five square miles of wetlands a year.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, the snow's thaw is drawing to a close and the mountain is shedding its white robe. Alarick and Moko are fishing in one of the mountain's springs and are catching nothing. They ask an old wise man to tell them where there might be fish. He points them towards the road to the "Ancient Mountain." They follow the road the old man told them about and reach a green luxuriant hill covered with fruit trees and streams. They think that this hill--smaller than their mountain, richer and greener--younger and simply hasn't grown up yet. Moko and Alarick explore the natural process of erosion.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, as the stars twinkle in the night sky, Moko is thinking of his village. Totemie asks him if she can join him in his quest for the end of the world. The next morning they leave Totemie's village and find their way to a desert where they find strange mountains and a bizarre twisting valley, deep and narrow, that seems to go on forever. A man crosses their path and tells them that only the pure of heart and courageous ever find the end of the deep valley. Filled with courage they set off to find it. Moko plays his flute and the mountains echo leads their way through the canyon's maze.
