Iris: Gps Measures Deformation in Subduction Zones: Ocean/continent

This resource looks at how geologists are able to measure the movement of tectonic plates using satellite-based data and how they were able to surmise in the past that the plates were moving. It also discusses how to read GPS time-series...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Where am I? The second installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program starts with pupils guessing the years in which major ocean exploration events took place. The instructional activity then...

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....

This animation shows that GPS can record the movement of the leading edge of the overlying continental plate in a subduction zone. [0:48]

Sink into an interactive learning experience about subduction zones! Junior oceanographers examine the earth-shaking and earth-making effects of subduction in the fourth installment in a 13-part series. Hands-on activities include...

A video exploring places where subduction zone causes volcanoes to form. [5:24]

Oblique view of a highly generalized animation of a subduction zone where an oceanic plate is subducting beneath a continental plate. [0:27]

[Free Registration/Login may be required to access all resource tools.] Covers convergent plate boundaries where an oceanic plate meets a continental plate.

This video explains the process of subduction between two oceanic plates as well as a continental plate and oceanic plate. Links to two additional subduction activities are also available.
