What else can I help you with?
Where do trenches form?
Treches are formed when an ocean plate subducts under a continental plate.
What are ocean treches made of?
Chocolate and unicorns.
How deep were the treches in World War 1?
About 7 feet deep
Where does the deepest earthquakes occur?
treches. 300 km or below sea level.
How deep trenches are formed?
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
What is a sea current?
A Deep Sea Current is a ocean current formed by density.
What is a island arcs?
it is a string of islands formed above a deep ocean trench
How is a deep ocean current formed?
Deep ocean currents are formed by differences in water temperature and salinity, as well as by the topography of the ocean floor. Cold, dense water sinks and flows along the bottom of the ocean, while warm water rises and flows along the surface, creating a continuous circulation pattern. This movement of water is also influenced by the rotation of the Earth and wind patterns.
Does the theory of continental drift state that ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
Yes
What are ocean trenches associated with?
Deep ocean trenches are associated with subduction zones where an ocean plate descends into the asthenosphere. The Ocean plate is heavier than a Continental plate which causes the Ocean plate to slide beneath the Continental plate. As the Ocean plate descends, a deep ocean trench is formed.
What does Deep Current mean?
A Deep Sea Current is a ocean current formed by density.
