|Dispatch from the Deep: Shaping the Ocean Floor at the Mid-Ocean Ridges|
This text reports on the experiences of a science teacher who joined a research expedition to study deep sea vents in the Pacific Ocean. It offers an engaging and informative overview of topics including the peaks, valleys, and plains that form the floor of the ocean and the internal heat that cracks the crust and causes it to move along plate boundaries. It also explains why submarine volcanoes form at mid-ocean ridges and how the intense pressure and cold water of the deep seas change the way lava flows to produce pillow lava. The author makes these observations from the deck of the research vessel Atlantis while the submersible research vessel Alvin dives below.
