Burial, compaction, and porosities in a subduction zone part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This activity introduces students to what happens to sediments buried in subduction zones. Students calculate the rate of burial in a subduction zone and compare it to burial by sedimentation on the ocean floor. They also examine porosities of sediments, how porosity changes with depth, and what porosities can tell scientists about water pressure.
