Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.
Is the analysis of seafoor sediments evidence of sea-floor spreading?
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
Which observation was not instrumental in formulating the hypothesis of sea floor spreading?
One observation that was not instrumental in formulating the hypothesis of sea floor spreading is the distribution of terrestrial fossils across continents. While these fossils provided evidence for continental drift, they did not directly relate to the mechanisms of sea floor spreading, which is primarily supported by observations such as the age of oceanic crust, magnetic stripe patterns on the sea floor, and the presence of mid-ocean ridges.
The maximum depth of the Atlantic ocean is 30246 ft This is 5049 ft deeper than the maximum depth of the Caribbean Sea What is the maximum depth of the Caribbean Sea?
The maximum depth of the Caribbean Sea is 25,197 feet.
Why are divers limited to depth when at sea?
because of the sea floor
How does the density of sea change with depth?
the density of sea increases with depth
What are two challenges of mapping the sea floor?
The depth and the vastness of the oceans.
Is the age of the sea floor the same age of the continents?
No. The sea floor is much younger than the continents. The oldest sea floor is about 200 million years old. The continents are billions of years old.
What is the depth of the sea cucumber?
its ranges from about 183 meters down to the floor its ranges from about 183 meters down to the floor
How does the age of seafloor sediments change the increasing distance from the oceans ridge?
age increases
What is the depth range of a sea cucumber?
its ranges from about 183 meters down to the floor its ranges from about 183 meters down to the floor
What is the reason for not drilling more of your own oil in the gulf of Mexico?
Depth of the sea floor. For example at 30,000+ feet of depth, it becomes increasingly difficult to drill for oil on the open sea.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
What discovery did scientist make when comparing the age of the sea floor to that of the continents?
The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!
What part of ocean creates the sea floor?
acually its the moon, since it causes the tides to pound against the water making depth
What can result if an earthquake causes a sudden vertical change in the sea floor?
A sudden vertical change in the sea floor during an earthquake can result in a tsunami. The movement of the sea floor displaces a large volume of water, which then forms powerful and destructive ocean waves that can travel long distances and cause widespread damage to coastal regions.
