Who has the most power if there is a national emergency?
The President . It is obvious as he is commander-in-chief. by the way the Navy dept had a short lived and somewhat sardonic acronym for this role- CINCUS pronounced ( Sink-Us!) Commander In chief, US-) Only He can sink us! With regard to aquatic scandals such as the Watergate (Nixon) and Whitewater (Clinton) it may be an apt choice but was ditched in favor of Potus- President of The US. CINCUs may still be used but a well it might be considered washed-up.

What causes some oceanic plates to sink and others to float?
All oceanic plates float on top of the mantle, and sink into the mantle underneath a less dense plate in plate collision zones.
When does a part of oceanic plate sink into the mantle?
Usually when it meets another tectonic plate at a convergent plate boundary. If the oceanic plate converges with a continental plate the denser oceanic plate will be forced under the continental plate. If it converges with another oceanic plate the older (and therefore cooler and denser) plate will be forced under the younger plate.
What ocean plate and continental plate colliding?
At this type of convergent boundary the oceanic plate will be subducted, or sink into the mantle underneath the continental plate. Volcanoes often form near these boundaries.
At deep ocean trenches what allows oceanic crust to sink back into the mantle?
Conduction. Heat istransferred from the mantle to the crust, melting it to become part of the mantle.
When a continental plate and an oceanic plate collide why does the oceanic plate sink below the continental plate?
It's because the oceanic plate is more dense than the continental plate.
Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?
Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle
What happens when oceanic and continental plates collide?
At this type of convergent boundary the oceanic plate will be subducted, or sink into the mantle underneath the continental plate. Volcanoes often form near these boundaries.
Can plate movement occur when a plate is pushed away from an ocean trench during a process called ridge push?
A convergent boundary between a continental plate and an oceanic plate results in a ocean trench because the basalt in the oceanic plate is denser than the granite in the continental plate, causing the oceanic plate to sink underneath, into the mantle.
Cooler older oceanic lithosphere sink into the mantle at?
Subduction zones or trenches.
Why do oceanic plates dive underneath continental plates when they collide?
this is because the oceanic plate is much denser than the continental plate so when they collide the oceanic plate will sink easily
When an oceanic plate collides with a continental plate which plate is subducted?
When an oceanic plate and a continental plate collide, the oceanic plate is always subducted. Oceanic plates are denser than continental plates, and they have a higher iron content. Since they are denser, oceanic plates always sink below the continental plate in the event of a collision.
Do magnetic stripes on the ocean floor oceanic crust sink back into the mantle?
Eventually the oceanic crust, along with the magnetically aligned minerals contained within, will be subducted into the mantle.
