What else can I help you with?
True or false sea floor sediments gradually thicken away from a mid-ocean ridge?
False. Sea floor sediments do not gradually thicken away from a mid-ocean ridge. Instead, the thickness of sediments can vary significantly depending on factors such as proximity to sources of sediment input, ocean currents, and tectonic activity.
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 are sediments produced by plants and animals in the sea called?
Sediments produced by plants and animals in the sea are called biogenic sediments. These sediments are composed of organic remains, such as shells, corals, and skeletal debris, which accumulate on the seafloor over time.
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 comprises the actual sea floor beneath sediments?
Basalt!
Deep-sea sediments contribute to continental growth how?
Deep-sea sediments most likely contribute to continent growth by being scraped off in a subduction zone and left at the surface.

Where does a River erode sediment?
sediments are transported by ocean rift, streams, river currents, wind (air). they are deposited according to size. The largest sediments are deposited first. The sediments settle into the sand and are carried by the stream. Near the mouth of the stream where the water moves slowly the small sediments settle out. The larger sediments get carried by the river into the sea then the samller sediments. The sea water dissolved minerals and soak the sediments and cement together. This eventually forms sediments.
Where are most carbonate sediments deposited on earth today?
The deep sea.
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
What is the type of water pollution that blocks sunlight and covers up the food sources?
sediments
What are two different sources for sediments in general?
Rivers and continental crust to continental crust.
