What states the youngest rocks of ocean floor are at a diverging boundaries moving outward?
seafloor spreading
What would you expect to find if you measured the temperatures of rocks on the ocean floor at various distances from a mid-ocean ridge?
If one was measuring the temperatures of rocks on the seafloor, the hottest rocks would be located nearest to a mid ocean ridge. This is the location where the hot magma from the asthenosphere rises and is situated on either side of the ridge. The farther away the seafloor is from the central area of heat, the colder it is. This pattern is identical on both sides of a mid ocean ridge. However, if rocks are located near subduction zones or hot spots, they too would be hotter than the majority of the seafloor.
What does seafloor spreading have to do with the theory of continental drift?
Seafloor Spreading helped move the Continents to their current location.
What is the usual amount of seafloor sediments in a given location?
500 to 1000 meters
What type of rocks from when magma erupts from undersea volcano?
All three rock types could be formed in areas under the seas. Two types of rock are most likely to form on the seafloor, however. Sedimentary rock is formed on the seafloor where accumulations of sediments undergo lithification processes. Extrusive igneous rock can form on the seafloor when lava erupts on its surface.
The youngest seafloor rocks are found?
Next to the sea potatoes
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.
What states the youngest rocks of ocean floor are at a diverging boundaries moving outward?
seafloor spreading
How does the age of rocks in the seafloor provide evidence of seafloor spreading?
Rocks in the seafloor are moving one place to another
How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
How did Harry Hess hypothesis explain seafloor spreading?
Harry Hess hypothesized that the sea floor was spreading. He explained it through the phenomena of the youngest rocks that are found only at the mid-ocean ridges. These rocks then, get progressively older when moving away from the ridge.
The oldest rocks on the seafloor are much younger than the oldest rocks on the continents?
true
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
Where can you find the youngest rocks on the ocean floor?
you can find the youngest rocks on the top of the ocean floor.
What is the youngest rock on the Earth?
Metaphoric Rocks are the youngest
