Regoliths in the Alluvium subcategory, that is loose rocks and soils which cover a layer solid rocks, found on the ocean floor are in part the result of glacial rafting. As a glacier calves into the ocean, it creates ice burgs. Because glaciers are so erosive, they often carry pieces of broken rock within their ice. As they float out to sea, they melt, and drop any debris that they are carrying. These form regoliths known as "drop stones" on the ocean floor, and are indicative of cold conditions. Alluvium may also be from volcanic activity, turbidite, or other weathering events.
Rocks exposed on the ocean floor, that are not regoliths, can indicate the direction of magnetic north when that rock formed.
What else can I help you with?
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.
What is the type of crust formed on the ocean floor?
Oceanic crust, formed mostly of mafic rocks, or sima, is found on the ocean floor.
What states the youngest rocks of ocean floor are at a diverging boundaries moving outward?
The youngest rocks of ocean floor are found at mid-ocean ridges, which are diverging boundaries where tectonic plates move apart. As new oceanic crust is formed at these ridges through volcanic activity, it pushes the older rocks away from the boundary, making the ridge the youngest part of the ocean floor.
What are the youngest rocks on the ocean floor?
The youngest rocks on the ocean floor are located at mid-ocean ridges, where new oceanic crust is constantly being formed through volcanic activity. These rocks are typically less than 5 million years old.
Where do most rocks have a basaltic composition?
Most rocks with a basaltic composition are typically found in oceanic crust, such as the ocean floors and mid-ocean ridges. Basaltic rocks are also common in volcanic regions like Hawaii and Iceland.
Is ocean floor smooth?
The ocean floor is not smooth.The ocean floor is made up of rocks, ledges and ditches.
The youngest rocks on the ocean floor are located where?
The youngest rocks on the ocean floor are located at mid-ocean ridges. These ridges are always found at divergent boundaries.
Why do you think that old rocks are rare one ocean floor?
There are no rocks on the ocean floor because they turn to sand. The moving of the water gradually wears away at the rocks.
Where can you find the youngest rocks on the ocean floor?
The youngest rocks on the ocean floor are typically found along mid-ocean ridges. These areas are where new oceanic crust is formed through volcanic activity and the process of seafloor spreading. As the magma cools and solidifies, it creates new rocks that are relatively young compared to rocks found in other parts of the ocean floor.
What will you find on the ocean floor?
sand,rocks
What is an ocean floor?
broken up rocks
What if old rocks are rare are on the ocean floor?
It is believed that old rocks are rare on ocean floors bevause the floor has manny remains and we are not unable to reach them
The youngest rocks in the ocean floor are located at the mid ocean?
Ridges
What is an ocean floor sediment?
broken up rocks
How do you obtain samples of ocean floor rocks?
mud
Is there rocks in the ocean?
Yes, because they make up the ocean sea floor.
Is it true that the magnetism of the rocks along the ocean floor is consistent in that there is no reversal of polarity?
The rocks of the ocean floor are not consistent and do show past reversal of polarity. The statement in the question is false.
