True or false sea floor sediments gradually thicken away from a mid-ocean ridge?
true
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
What type of rock would most likely be at a subduction zone convergent boundary?
Sea floor bassalt and sediments.
How do lithogenous sediments differ from biogenous sediments?
Lithogenous sediments come from the land They result primarily from erosion by water, wind, and ice Biogenous sediments originate from organisms The particles in these sediments come from shells and hard skeletons. Although lithogenous sediments represent the largest total volume, biogenous sediments cover a greater area of sea floor
How do the ages of the sea sediments compare to the age of the oldest contential rock?
Continental rock is MUCH older than sediments in the sea (unless the sediments in the sea come from continental crust, in which case they would be the same age).
What comprises the actual sea floor beneath sediments?
Basalt!
What are thought to represent the original sea floor because sediments top them?
abyssal hills

How are plankton sediments formed?
As plankton die, it sinks to the sea floor, and over many years, a sediment is formed.

How does the age of seafloor sediments change the increasing distance from the oceans ridge?
age increases

Continental rock is MUCH older than sediments in the sea (unless the sediments in the sea come from continental crust, in which case they would be the same age).
What is deep sea plain?
A deep sea plain, sometimes called an abyssal plain is a wide, almost level area that covers about two-thirds of the entire ocean floor. There is a complete absence of river sediments on this plain.
