Ocean Floor Geomorphology

Geomorphology studies the relief of land and of the ocean and sea floor from the standpoint of its external physiognomic appearance origin age history of development and present dynamics as well as of the laws of grouping and distribution of the forms that make up the relief.

Ocean floor geomorphology.

The morphological and geological structures of the sea floor primarily reflect plate tectonics and sedimentation over the last 200 million years. The ocean floor is dynamic and has changed over the years due to tectonic activity. Seafloor geomorphology is the scientific study of the formation alteration and configuration of seabed features and their relationship with the underlying geology. The continental margins the mid ocean ridges and the deep ocean floors.

They are the deepest parts of the ocean. Seamounts and guyots 12. The gsfm includes 131 192 separate polygons in 29 geomorphic feature categories used here to assess differences between passive and active continental margins as well as between 8 major ocean. In this activity a sealed shoe box with a varied topography made out of clay will be measured by taking depth soundings with a skewer.

The abyssal plain is the flattest of all earth s surface areas. The geomorphology of the seafloor is viewed in this study as a hierarchy of base layers for the shelf slope abyss and hadal zones overlain by classification layers and discrete feature layers table 1. The overarching theme of this book and for the geohab organisation in general is that mapping seafloor geomorphic features is useful for understanding benthic habitats. Ocean acidification and dry ice.

I abyssal plains. The ocean basin floor 1. The deepest spot of all is the challenger deep which lies in the mariana trench in the pacific ocean near the island of guam. Geomorphology the science of the relief of the earth s surface.

Plate tectonics is the theory in which the earth s lithosphere crust and upper mantle layer is fragmented into pieces that are constantly moving and changing the geological features of the planet. Many of the case studies. Some areas of the ocean floor also have deep narrow depressions called trenches. It is 10 920 meters 35 827 ft below the ocean surface.

There are convergent boundaries in. The sea floor is divided into three principal provinces.
