How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
Where are the youngest seafloor rocks found?
The youngest seafloor rocks are found in the rift valleys of the mid ocean ridges. At the mid-oceanic ridges there is tectonic movement bringing new magma to the surface.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
because that there are younger rocks found at ocean ridges than the ones found near deep-sea trenches
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
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.
Where are the youngest rocks in the ocean located?
mid-ocean ridges
What is the temperature of the young rocks at the mid ocean ridges?
The youngest rocks at the mid ocean ridges are those that have just solidified from molten magma. Very hot.
The youngest rocks in the ocean floor are located at the mid ocean?
Ridges
What rocks are located at mid ocean ridges?
Igneous.
What has the author Karlis Muehlenbachs written?
Karlis Muehlenbachs has written: 'Oxygen isotope studies of rocks from mid-ocean ridges' -- subject(s): Analysis, Mid-ocean ridges, Rocks, Submarine geology
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
Where are the youngest oceanic rocks found?
At mid-ocean ridges which are divergent plate boundaries.
The oldest rocks are located at mid-ocean ridges?
Nope. The oldest rocks are located on continents, usually away from the ocean. The mid-ocean ridges are, in fact, home of some of the youngest rocks. The reason for this is what is called sea-floor spreading. Mid-ocean ridges form at places where oceanic plates diverge, or move apart. As this happens, magma rises from within the Earth to fill the gap. The magma cools and solidifies, creating new seafloor. This process continues as the plates continue to spread apart.
Is the Rock found at mid ocean ridge old or young?
yes young rocks are found at mid ocean ridges not old rocks.
Where are the youngest seafloor rocks found?
The youngest seafloor rocks are found in the rift valleys of the mid ocean ridges. At the mid-oceanic ridges there is tectonic movement bringing new magma to the surface.
How old are rocks in ocean crust?
The age of rocks in the ocean crust depends on where the rocks are collected. Scientists collected rock samples from the sea floor. They found out that rock samples that were closer to mid-ocean ridges were younger than the samples farther away from the ridges. So pretty much you could get rocks that are thousands of years old to over millions of year old.
