Forms by lava from volcanoes on the sea floor
What else can I help you with?
Where are the youngest rocks in sea-floor spreading?
The youngest rocks in sea-floor spreading can be found at the mid-ocean ridges, where new oceanic crust is formed. As tectonic plates pull apart, magma rises to the surface and solidifies, creating new rocks. These rocks are typically less than a few million years old.
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.
Process in which new sea floor forms as older sea floor is pulled apart?
sea-floor spreading
Why are magnet patterns important evidence for plate tectonics?
magnetic rocks on the ocean floor show that the Earths magnetic field has been frequently reversed forming new sea floor.
How does the banding pattern of rocks and the dating of these rocks give evidence of sea floor spreading?
The banding pattern of rocks on either side of mid-ocean ridges shows symmetrical stripes of magnetic reversals, indicating that new crust is formed at the ridge and then moves outward as tectonic plates diverge. This magnetic pattern correlates with the age of the rocks, with younger rocks found closer to the ridge and older rocks further away. The consistent dating of these rocks supports the theory of sea floor spreading, demonstrating that new oceanic crust is continuously generated while older crust is pushed away. Together, these patterns provide strong evidence for the dynamic processes of plate tectonics and sea floor spreading.
What happens in sea-floor spearding?
new rocks form
How does new ocean floor form?
Sea Floor Spreading!
Why are sea floor rocks so young?
Sea floor rocks are young because of the process of seafloor spreading at mid-ocean ridges. As new oceanic crust forms at the ridges, older rocks get pushed further away. This continuous process creates a relatively young age for the sea floor rocks, with the oldest rocks being around 200 million years old.
Where does new rock form on the floor?

Where are the youngest rocks in sea-floor spreading?
The youngest rocks in sea-floor spreading can be found at the mid-ocean ridges, where new oceanic crust is formed. As tectonic plates pull apart, magma rises to the surface and solidifies, creating new rocks. These rocks are typically less than a few million years old.
How do rocks form from remains of animals?
Limestone is formed from the skeletal remains of minute sea creatures, laid down on the sea floor millions of years ago.
What pushes up through rifts in the ocean floor and cools to form new sea floor?
sea floor spreading, boo. it's molten rockk from earth's coree. hope it helpped!! :)
How magnetic symmetry can be used as evidence of sea floor spreadding?
On each side of the mid-ocean ridge is a mirror of the striped pattern on the other side. When drawn, these patterns show alternating bands of normal and reverse polarity that match the geomagnetic reversal time scale, scientists can assign ages to the sea-floor rocks. The youngest rocks were at the center, and the older rocks father away. The ages of the sea floor rocks are symmetrical. The only place on the ocean-floor where new rocks are formed are at the rift in mid-ocean ridge. hope this helps :)

How scientist date sea floor rocks?
looking at patterns
What are types of evidence that the sea floor is expanding?
Rocks have a north and south pole. The sea floor was discovered to have different magnetic poles on cracks in the ocean floor.
What is the process that creates new ocean crust to form molten rock?
Sea Floor Spreading
