Sea Floor Spreading

After reviewing plate tectonic theories and the discovery of both the Atlantis Massif and the Lost City hydrothermal vents, earth science learners complete a worksheet and participate in discussions about what the types of rock found...

Students explore the basic concept of seafloor spreading. They describe the processes involved in creating new seafloor at a mid-ocean ridge. They investigate the Galapagos Spreading Center system.

Young scholars create a paper model to illustrate sea-floor spreading.

Take a deep dive into oceanography. The online interactive allows for learners to board a submersible to dive to the bottom of the ocean to investigate sea vents. On the way down, individuals see different marine life at different...

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.

Students build ocean floor structures, then map and model an unfamiliar ocean floor. They are introduced to bathymetry and sea floor features, and discover one of the most widely usd methods for studying the ocean.

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.

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

Instructional module focusing on the development of plate tectonic theory. Discussion includes the evidence of Pangaea, and the processes of seafloor topography and seafloor spreading. Site also includes an interactive practice quiz and...
