WebNemertea is also known as ribbon worms because of their long, ribbon-like bodies. They are found in marine and freshwater habitats worldwide, including deep sea trenches and freshwater lakes and streams. Nemertea feed on a wide range of prey, including small fish, crustaceans, and other invertebrates. Some species of Nemertean reproduce ... Web3.7 Tectonic Plate Boundaries Places where oceanic and continental lithospheric tectonic plates meet and move relative to each other, are called active margins (e.g., the western coasts of North and South America). A location where continental lithosphere transitions into the oceanic lithosphere without movement is known as a passive margin (e.g., the …

Operated by the National Oceanic and Atmospheric Administration (NOAA), two tsunami warning centers are staffed 24 hours a day, 7 days a week. These centers monitor for tsunamis and the earthquakes … Webocean trenches and ridges. Trench: very deep, elongated cavity bordering a continent or an island arc; it forms when one tectonic plate slides beneath another. Ridge: underwater mountain range that criss-crosses the oceans and is formed by rising magma in a zone where two plates are moving apart. previous. next. shanghai tork drive equipment co. ltd

Web17 apr. 2024 · As with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed. The Marianas Trench (paralleling the Mariana Islands), for example, marks where the fast-moving Pacific Plate converges against the slower moving Philippine Plate. WebEarth Science Deep ocean trenches are formed when a continental plate descends underneath an oceanic plate. This is commonly a process of plate tectonics. The Earth’s lithosphere is divided into 17 large tectonic plates and about 20 smaller plates, all of which are continuously moving with respect to each other. shanghai top universities
