One piece of evidence supporting sea floor spreading is the age of oceanic crust, with younger crust found at mid-ocean ridges and progressively older crust as you move away from the ridge. Another piece of evidence is the presence of magnetic striping on the ocean floor, which shows alternating magnetic orientations that align with Earth's magnetic field reversals over time.

What do magnetic reversals help support?
Magnetic reversals in Earth's history help support the theory of plate tectonics by providing evidence of seafloor spreading and the movement of lithospheric plates. They also assist in dating rocks and determining the age of oceanic crust.
What evidence was used to support continental drift?
Evidence supporting continental drift includes the fit of the continents like pieces of a giant jigsaw puzzle, matching geological features across different continents, similarities in rock formations and mountain chains, distribution of fossils across continents, and the pattern of magnetic stripes on the ocean floor that support seafloor spreading. These pieces of evidence collectively support the theory of continental drift proposed by Alfred Wegener.
How is magnetism used to support the theory about seafloor spreading?
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.
How long was it before new evidence emerged to support wegener's original theory?
It took several decades before new evidence emerged to support Wegener's original theory of continental drift. In the 1960s, significant discoveries such as seafloor spreading and plate tectonics provided strong evidence to confirm Wegener's ideas. This eventually led to the widespread acceptance of the theory of plate tectonics in the scientific community.
Is plate tectonics the main lines of evidence are fossils climate clues rock and the theory of seafloor spreading?
Yes, plate tectonics is supported by various lines of evidence such as fossils showing similar species on different continents, climate clues like ancient glaciers in tropical regions, rock formations matching across continents, and the theory of seafloor spreading confirmed by magnetic striping on the ocean floor. These pieces of evidence collectively support the concept of plate tectonics and the movement of Earth's lithosphere.
How do the ages of rock 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.
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.
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
What are 4 pieces of evidence4 alferd wegner used to support this theory?
Four pieces of evidence used by Alfred Wegener to support his theory of continental drift were the fit of the continents, matching geological formations across continents, similar fossil distributions, and glacial evidence in tropical regions.
What are the four pieces of evidence that support the theory of evolution?
The four pieces of evidence that support the theory of evolution are the fossil record showing transitional forms, homologous structures in different species indicating a common ancestor, genetic similarities between different species, and observable examples of natural selection in action.
What do magnetic reversals help support?
Magnetic reversals in Earth's history help support the theory of plate tectonics by providing evidence of seafloor spreading and the movement of lithospheric plates. They also assist in dating rocks and determining the age of oceanic crust.
What evidence was used to support continental drift?
Evidence supporting continental drift includes the fit of the continents like pieces of a giant jigsaw puzzle, matching geological features across different continents, similarities in rock formations and mountain chains, distribution of fossils across continents, and the pattern of magnetic stripes on the ocean floor that support seafloor spreading. These pieces of evidence collectively support the theory of continental drift proposed by Alfred Wegener.
What evidence is there to support the theory of sea floor spreading?
the newer rock is closer to the middle n th older ones spread along the sides

Evidence that supports the theory of evolution is called?
Fossil records, anatomical similarities, embryological development, and genetic similarities are all forms of evidence that support the theory of evolution. These pieces of evidence show the gradual changes in species over time and provide support for the idea that all organisms are related through common ancestry.
