As shown on the History Channel. Four and a half billion years ago, the Earth formed from dust in space to become a molten ball of rock orbiting the Sun. Travels back in time to investigate how the fledgling planet survived a cataclysmic cosmic collision with another world, how molten rock solidified to land, how our oceans filled with water, and how life arrived on Earth. Geologists study the oldest rocks on Earth and meteorites from outer space to solve the geological mystery of all--the birth of the Earth.
In this segment, students learn all about different types of energy found on Earth. Solar energy comes from the sun, and geothermal energy is generated and stored in the earth. Students also discuss these forms of energy and how the energy of the earth transfers heat through the convection process. Part of the "Earth Science" series.
As shown on the History Channel. In the remote wastes of Siberia buried under snow are the remains of one of the greatest catastrophes that the Earth has endured. 250 million years ago, huge volumes of lava spewed out onto the surface--so much that it would have buried the whole of Texas under one mile of lava. At first the temperature dipped but then the greenhouse gases that escaped from the depressurized lava caused a massive global warming. It wreaked havoc, and 95% of the species on Earth became extinct. Yet life hung on and in time this disaster paved the way for the next phase of life on earth--the age of the dinosaurs.
How did the universe form? Where did it come from? Where does Earth fit into the equation? This segment focuses on Earth's place in the universe. Other topics covered include the solar system, gravity, planetary experience, and stars. Part of the "Earth Science" series.
Human actions can have positive and negative impacts on Earth. Students will learn ways to make sure they help preserve the Earth.
Part of the Project-Based Inquiry Science "Earth Science Content Videos" series. Modules include the following: "Mantle Simulation: Hot Water in Cup," "Mantle Simulation: Cold Water in Cup," "Mantle Simulation: Cardboard," and "Plate Interaction Animations."
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.
This segment answers the questions surrounding the origins of Earth. Scientists use clues from the past to help explain how Earth formed. Other topics covered include matter, minerals, and rocks. Part of the "Earth Science" series.
Plate tectonics describes the large-scale motion of large and small plates of the earth's lithosphere. As the plates slide past one another, they create friction and heat. The tension caused by the friction of heat is released either through earthquakes or volcanoes. Part of the "Earth Science" series.
Introduces students to our planet Earth and its place in the solar system. Explains that Earth's unique position makes it conducive to life. Also explains the basics of earth science, including the water cycle, weather, and continents. Short review.
Volcanoes and earthquakes! Geysers and boiling mud! Natural forces like these have been working for millions of years, changing the surface of the earth. Examines the layers of earth, a history of continental drift, plate tectonics, and other phenomena at work on our planet.
Students will learn practices for keeping the Earth healthy. The video distinguishes between unstainable and sustainable practices.
Earth has many systems and cycles that help regulate the processes needed to sustain life. These systems are susceptible to human impact. Part of the "Earth Science" series.
Part of the animated "Johan, the Young Scientist" series. Johan wonders why people don't fall off Earth if it really is round. He travels to ScienScape to find out. Professor Hoo sends Johan, Ani, and Moki to Earth to work on an experiment.
What is a seismic wave? Which of the four types is most destructive? Discover the science behind earthquakes with this animated video.
How can individuals help protect the environment? This program explores a wide variety of practical, easy-to-accomplish tasks individuals can do to make Earth a healthier place. Pollution prevention, natural resource use, and recycling are some of the key ideas highlighted.
The path the Earth takes around the sun is in just the right place. The trajectory of the Earth's orbit ensures life is able to exist, and this orbital journey influences almost everything on Earth. Part of the "Orbit: Earth's Extraordinary Journey" series.
Explains why Earth is precious and how it is being damaged. Special attention is paid to how individuals can conserve natural resources and care for the planet.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term earth. Part of the Science Video Vocab Series.
Host award-winning geoscientist, Richard Alley provides an eye-opening look at some of the world's most important case studies in smart energy. Alley travels to Spain and Morocco where large-scale solar farms and individual photovoltaic panels atop tents in the Sahara are beginning to bring the vast potential of the sun down to Earth. In Brazil, abundant natural resources are transformed into efficient, sustainable biofuel, making Brazil the only nation whose cars could keep running if all gasoline were to vanish. In Denmark, and West Texas, citizens have taken sustainability into their own hands by becoming stakeholders in wind turbines. And in China, he explores multiple sustainable energy technologies, including exclusive footage from GreenGen, the world's most advanced low-carbon emissions power generation plant.
