Why does oceanic lithosphere sink at subduction but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together

Why are the continents very young?
mid-ocean ridges and subduction zones
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What are the landforms at divergent ocean plate boundaries?
Occasionally, mid-ocean ridges are found at a divergent boundary. Another feature that is made is a rift valley. Also, earthquake activity at fracture zones alone mid-ocean ridges, and volcanic activity
New ocean crust is formed at?
Divergent plates or mid-ocean ridges
Isochron maps indicate what about the seafloor of the ocean crust?
Well i think that can be one of those a) oldest near ocean ridges b) Youngest hear ocean ridges c) Youngest at deep-sea trenches d) Thinnest in subduction zones
Subduction occurs where the oceanic crust bends down toward the mantle at a(n)?
Seafloor spreading occurs along mid-ocean ridges. Mid-ocean ridges are large mountain ranges on the ocean floor. The shifting in the rock causes the seafloor to spread and allows magma to bubble and form more mountains on the ocean floor.
How is a hot spot similar from a subduction zone?
Most volcanoes that cannot be ascribed either to a subduction zone or to a seafloor spreading at mid-ocean ridges are attributed to hot spots.
What are 3 different types of earthquakes?
(1)mid ocean spreading ridges, (2) subduction zones, and (3) transform faults.
What occurs along ocean trenches but not along mid ocean ridges that accounts for the occurrence's of deep focus earthquakes?
Subduction of oceanic crust. The Earthquakes occur at depth in the descending slab.
Where is lithosphere being consumed?
New oceanic lithosphere is constantly being produced at mid-ocean ridges and is recycled back to the mantle at subduction zones.
