What three types of evidence provided support of the theory of sea floor spreading?
three are :
eruptions of molten material
magnetic stripes in the rock of the ocean floor
and
the ages of the rocks themselves

What three types of evidence provided support of the theory of sea-floor spreading?
three are : eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselves :)
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.
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.
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.
Why did people believe Harry Hess and not believe Alfred Wegener?
Harry Hess proposed the theory of seafloor spreading, which provided physical evidence for the movement of the Earth's crust. Alfred Wegener proposed the theory of continental drift, which lacked a mechanism to explain how continents moved. Hess's theory had more scientific support and evidence, leading to greater acceptance by the scientific community.
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 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
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 did Alfred Wegeners theory support the theory of seafloor spreading?
Alfred Wegener's theory of continental drift suggested that continents move over time on Earth's surface. This theory provided support for the concept of seafloor spreading, which explains how new oceanic crust forms at mid-ocean ridges and spreads outward. Both theories contributed to the development of the theory of plate tectonics, which explains the large-scale movements of Earth's lithosphere.
Which type of plate movement provided some evidence to help support weg ners theory?
divergence, convergence ,shear /transform
Is it true that Alfred wegner provided evidence from landforms and climate in support of his theory of the shrinking earth?
No, Alfred Wegener provided evidence from continental drift and fossil distribution to support his theory of plate tectonics, not a shrinking Earth. Wegener's theory suggested that the continents were once connected in a single landmass (Pangaea) and drifted apart over time due to the movement of tectonic plates.
How did research from the Glomar challenge help scientist support the theory of seaflooding spreading?
From Wikipedia: Starting from August 1968, the Glomar Challenger embarked on a year-long scientific expedition, the Deep Sea Drilling Program, criss-crossing the Mid-Atlantic Ridge between South America and Africa and drilling core samples at specific locations. When the age of the samples was determined by paleontological and isotopic dating studies, this provided conclusive evidence for the seafloor spreading hypothesis, and, consequently, for continental drift.
