Where are the youngest seafloor rocks found?
The youngest seafloor rocks are typically found along mid-ocean ridges, where tectonic plates are moving apart and new crust is continually forming. This process, known as seafloor spreading, leads to the creation of young rocks that are progressively older as you move away from the ridge axis on either side.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
Ocean-floor rocks near mid-ocean ridges show a symmetrical pattern of magnetized stripes parallel to the ridge axis. These stripes result from periodic reversals in Earth's magnetic field and provide evidence of seafloor spreading. Sediments on the ocean floor also show younger ages near the ridges, supporting the idea of seafloor spreading.
Isochron maps indicate what about the seafloor of the ocean crust?
Isochron maps indicate the age of the seafloor on the ocean crust. They show patterns of different ages of the oceanic crust moving away from mid-ocean ridges, where new crust is being formed. Younger crust is found closer to the ridges, while older crust is found farther away.
Give two pieces of evidence for seafloor spreading?
Paleomagnetic stripes on either side of mid-ocean ridges demonstrate the symmetric pattern of magnetic reversals found in oceanic crust, supporting the idea of seafloor spreading. Age dating of oceanic crust samples reveals that the further away from mid-ocean ridges, the older the crust gets, providing direct evidence for the continuous creation of new seafloor at spreading centers.
Do you have evidence of seafloor spreading?
I don't have evidence, but oceanographers have evidence. In mid ocean ridges, more and more molten rocks come up from the surface and cool down. As a result, the rocks already there get pushed away. We did find molten rock coming up from the mantle. Also, when scientist carbon dated the rocks on mid ocean ridges, they found that the farther you go outward, the older the rock. That's another sign. There's more but i can't think of it now. Hope this helps.

Where can ocean ridges be found?
They are usually found in mid-ocean, where the seafloor is spreading. An example is the Mid-Atlantic Ridge.
Where are most divergent boundaries found?
On the seafloor. Yes, the mid oceanic ridges are all divergent boundaries.
Which seafloor feature is not found on active continental margins?
continental rise
What seafloor feature is not found on active continental margins?
continental rise
Where are the major volcanic mountains found?
Along the mid oceanic ridges.

What are the landforms at divergent ocean plate boundaries?
Occasionally, mid-ocean ridges are found at a divergent boundary. Another feature that is made is a rift valley. Also, earthquake activity at fracture zones alone mid-ocean ridges, and volcanic activity
Abyssal hills are found on the seafloor between?
Abyssal hills are found on the seafloor between abyssal plains and oceanic ridges. They are typically smaller in size and are formed by volcanic and tectonic processes, providing an uneven topography in the deep ocean. Abyssal hills can also be areas of increased seismic and volcanic activity.
Isochron maps indicate what about the seafloor of the ocean crust?
Isochron maps indicate the age of the seafloor on the ocean crust. They show patterns of different ages of the oceanic crust moving away from mid-ocean ridges, where new crust is being formed. Younger crust is found closer to the ridges, while older crust is found farther away.
Where are most hydrothermal vents found?
Hydrothermal vents are found along seafloor spreading centers on the bottom of the oceans.
What parts are youngest on earth's crust?
Directly along active oceanic ridges, such as the mid-oceanic ridge in the Atlantic (which Iceland straddles) and on active volcanoes, such as Hawaii. When lava from volcanoes such as Hawaii and the mostly undersea volcanoes of mid-oceanic ridges cools, it solidifies into brand new rock.
