Focus: Where are and what happens at cold seeps and how scientists study them. Learning objectives: After this lesson, students should be able to: Relate different datasets by observing and describing scientific maps Differentiate between carbon dioxide and methane gas Clarify misconceptions about greenhouse gas Explain what cold seeps are and why most gas/methane hydrates occur at continental margins Describe some of the methods scientists use to locate and study methane/gas hydrates Prerequisites: Prior to this lesson, students should be familiar with understanding maps, molecular structure and bonding, and the greenhouse effect and gases. Key words: Arctic Ocean, Methane, Carbon Dioxide, Gas Hydrate, Cold Seep, Greenhouse Gases.
