Introduction to Ocean Sciences, 2e Ocean science is an interdisciplinary field, one that involves physical, chemical, biological, and geological processes. Here you can see some of those processes in action. The following animations were developed by Stephen Marshak for Earth: Portrait of a Planet, Second Edition.

The Changing Oceans The face of the Earth is always changing and throughout geologic history oceans have been created and destroyed. Modern geologic evidence indicates that the ocean bottom is moving at a rate from about one-half to six inches a year through a process called plate tectonics. Roughly 200 million years ago the Earth's surface was very different from the familiar pattern of land we know today. All of the land masses were grouped together into one vast supercontinent called Pangaea. The rest of the globe was covered by a single great ocean known as Panthalassa. Earth's Continental Plates - ZoomSchool.com All About Plate Tectonics:Earth's Plates and Continental Drift The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle.
Geologic Time Initially compiled by Laurie Cantwell, Montana State University This section highlights animations, images, interactive graphics and videos used to teach the concept of geologic time in an introductory geology course. Visualizations cover the specific topics of earth history, relative age dating and life through geologic time. 2016 January 25 - Where Your Elements Came From Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2016 January 25 Explanation: The hydrogen in your body, present in every molecule of water, came from the Big Bang. How to Extract DNA from Anything Living First, you need to find something that contains DNA. Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas.
Ring of Fire The Ring of Fire is a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean. The Ring of Fire isnt quite a circular ring. Its shaped more like a 40,000-kilometer (25,000-mile) horseshoe. A string of 452 volcanoes stretches from the southern tip of South America, up along the coast of North America, across the Bering Strait, down through Japan, and into New Zealand. Feed the Dingo - A Fun Game About Ecosystems Feed the Dingo is a fun game that teaches students about the importance of maintaining balanced ecosystems. In the game students have to build and maintain a desert ecosystem. The game begins with a blank slate to which students have to add plants and animals. The game plays out over twelve virtual days. Each day students have to add more elements in order to maintain balance in the ecosystem. At the end of each day students are given feedback as to which plants and animals are healthy, which are in danger, and which have died.
Helping students understand text structures: Informational problem/solution Learning outcomes Students will learn to do a close reading of a problem/solution text and to analyze both what the text says and what the text does. From this close reading and analysis, students will observe and understand problem/solution text structures and will be able to replicate the structure in their own writing.
