What discovery about the the ocean floor is associated with the seafloor spreading?
Seafloor spreading, a key concept in plate tectonics, was significantly supported by the discovery of mid-ocean ridges and the symmetrical patterns of magnetic anomalies on either side of these ridges. As magma rises and solidifies at the ridges, it creates new oceanic crust, pushing older crust away. This process also revealed that the ocean floor is constantly renewing itself, contributing to our understanding of continental drift and the dynamic nature of Earth’s geology.

Sea floor spreading
What ocean-floor feature is associated with areas where oceanic crust is broken down?
The mid ocean ridge is the area of the ocean floor that is associated with the breaking down of the oceanic crust. This area is known for seafloor spreading.
How were different groups of scientists involved in the research and discovery of seafloor spreading?
Different groups of scientists, including geophysicists, geologists, and oceanographers, contributed to the research and discovery of seafloor spreading in the mid-20th century. Geophysicists like Harry Hess proposed the theory based on evidence such as magnetic striping on the ocean floor. Geologists like Fred Vine and Drummond Matthews further supported the theory with their work on marine magnetic anomalies. Oceanographers collected data from the seafloor to provide additional evidence for seafloor spreading.
How has knowledge of mid-ocean ridges changed as a result of evidence for sea-floor spreading?
Before the discovery of seafloor spreading, mid-ocean ridges were thought to be static features. However, with evidence for seafloor spreading, it was realized that new oceanic crust is forming at mid-ocean ridges, pushing older crust away and causing the seafloor to spread apart. This discovery fundamentally changed our understanding of plate tectonics and the geologic processes happening at mid-ocean ridges.
How does the ocean floor move?
It is called Seafloor Spreading, which comes under the Divergent Plate Movement.
Who had the sea floor spreading theory?
Harry Hess came up with the theory of seafloor spreading . Alfred Wegener came up with the idea of continental drift NOT sea-floor spreading.

What ocean floor features are associated with areas where oceanic crust is broken down?
Ocean floor features associated with areas where oceanic crust is broken down include mid-ocean ridges, deep-sea trenches, and volcanic island arcs. These features are formed through processes such as seafloor spreading, subduction, and volcanic activity along tectonic plate boundaries.
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 geologic discovery in the 1960's provided the scientific evidence to verify the occurrence of continental drift?
The discovery was the presence of magnetic stripes on the ocean floor which indicated that the seafloor was spreading, solidifying from melt, and the magnetic minerals contained therein were aligning themselves with the magnetic alignment of the Earth at the time of their solidification.
What evidence in rocks supports the theory 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.
How do the ages of the rocks on the ocean floor 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.
