What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.

What is the process that makes old oceanic crust go into the mantle?
makes up the bottom of the world's oceans is Magma from the underlying mantle erupts at the edges, then cools and solidifies to form new ocean crust.plate a process called seafloor spreading and back into the.
How is seafloor spreading different continental drift?
seafloor spreading is when molten material rises and cools down and makes new seafloor, continental drift is the theory that the continents were once together and the big land mass is called Pangea.this is fake story no one believe it i got wrong
What process makes new crust when the sea floor moves apart and magma rises up?
The process that makes new crust when the sea floor moves apart and magma rises up is called seafloor spreading. Magma from the mantle rises to the surface at mid-ocean ridges, cools, and solidifies to form new crust as the tectonic plates move apart. This process contributes to the continuous growth of the seafloor and the expansion of the ocean basins.
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
What is the process by which new crust is created when the seafloor moves apart and magma rises up?
This process is called seafloor spreading. It occurs at divergent plate boundaries where tectonic plates move apart. Magma rises up from the mantle through the cracks, solidifies upon contact with the cold seawater, and forms new oceanic crust.
What happens to magma that rises though cracks on the seafloor?
When magma rises through cracks on the seafloor, it can result in the formation of underwater volcanic structures like mid-ocean ridges or seamounts. As the magma reaches the surface, it can solidify and create new oceanic crust through a process called seafloor spreading. Eruptions can also produce hydrothermal vents, which support unique ecosystems due to the extreme conditions.
What is seafloor plains?
large regions of the seafloor that appear flat but are not
Seafloor is the process by which new crust is created when the seafloor moves apart and magma rises up?
Seafloor spreading is a geological process where tectonic plates move away from each other, allowing magma from the mantle to rise and solidify, creating new oceanic crust. This process occurs at mid-ocean ridges and is a key component of plate tectonics theory.
What age is the oldest rocks from the seafloor?
The oldest rock are up to 125 million years old.
What are eroded rock fragments and shells of marine creatures called that pile up on the seafloor?
Basalts
