Actvity Summary: Students will interpret data collected from CORKS to explain hydrostatic pressure and seismic changes that occur during tectonic activity.

This lesson has students interpret data from monitoring equipment installed within holes in the ocean floor from which sediment cores have been removed. Data on fluid pressure within seafloor sediment and rock will be used to explain tectonic activity of the Juan de Fuca Plate. Before conducting this lesson, students should be familiar with tectonic plates and associated structures, processes, and hazards (e.g., faults, earthquakes, hydrothermal vents, volcanoes).

This lesson has been revised and updated based on CORKs in the Crust.
