The Galapagos Spreading Center

Learners discover the uniqueness of deep sea hydrothermal vent organisms through an exploration of the NOAA Galapagos Rift Expedition. They study the genetics and evolution of a shrimp species that lives near the vents then they...

Students create a paper model to illustrate sea-floor spreading.

[Free Registration/Login may be required to access all resource tools.] Describes features of the seafloor and how they are mapped by echo sounding. It touches upon the continental margin as well.

This is a comprehensive website featuring how to build a model that illustrates sea-floor spreading and subduction. It has diagrams and pictures reviewing major geological concepts.

Watch a video depicting the formation of a mid-ocean ridge. The resource also has two additional lessons requiring you to apply your knowledge of mid-ocean ridge location and formation.

[Free Registration/Login may be required to access all resource tools.] Covers seafloor spreading and the mechanism for continental drift.

Students investigate magnetic evidence that supports the theory of sea floor spreading.

Learn what the Mid-Atlantic Ridge is, how it was formed in the Triassic Period, the volcanic activity that takes place there, and the benefits and negative impact of this activity.

In this seafloor spreading worksheet, students find mistakes in statements that are descriptive of seafloor spreading. Students correct the given sentences to make a true statement.

Students examine how geologists determine rates of sea floor spreading between two tectonic plates. They apply mathematical concepts such as the calculation and use of velocities and conversion from one set of units to another.
