What is the usual amount of seafloor sediments in a given location?
The amount of seafloor sediments can vary widely depending on location. Generally, it ranges from a few centimeters to several kilometers thick. Factors such as proximity to land, ocean currents, and sediment sources influence the accumulation of sediments on the seafloor.
What are the youngest sediments found compared to the mid-Atlantic ridge?
The youngest sediments found near the Mid-Atlantic Ridge are typically associated with the oceanic crust formed at the ridge itself, which is less than a few million years old. These sediments primarily consist of pelagic clay, biogenic material, and volcanic ash, accumulating as the seafloor spreads. The rate of sedimentation is relatively low, meaning that the youngest sediments are generally found closest to the ridge and become progressively older with distance from it.
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.
Which ocean is growing due to seafloor spreading?
The Atlantic Ocean is growing due to seafloor spreading. The Mid-Atlantic Ridge runs down the center of the Atlantic, where new oceanic crust is continuously formed as tectonic plates pull apart. This process contributes to the widening of the Atlantic Ocean.
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge

Why are the magnetic strips in the pacific ocean wider than the ones in the Atlantic ocean?
The Pacific seafloor formed at a faster spreading rate than the Atlantic seafloor.
What caused the Atlantic ocean to widen?
seafloor spreading
How does the age of seafloor sediments change the increasing distance from the ocean ridge?
age increases
What are the different types of seafloor sediments?
Undisturbed seafloor sediments will carry a history of what has transpired there, much like glacial ice or peat bogs. Some interesting and potentially valuable mineral deposits are also found on the seafloor, eg. manganese nodules, metals from black smokers, and of course, deep in the rock, oil.

Sediments derived primarily from the products of weathering on the continents are called .?
terrigenous or continental sediments
How does the age of seafloor sediments change with increasing distance from the ocean ridge?
Age of seafloor rock and sediment increases with distance from the oceanic ridges.
Most oceanic gas hydrates form when?
bacteria break down organic matter in seafloor sediments
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge
