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.
Scientists prove seafloor spreading through various methods, including mapping of magnetic stripes on the ocean floor, analysis of seismic activity, and examination of rock samples collected from the ocean crust. These techniques provide evidence of tectonic plate movement and the creation of new oceanic crust at mid-ocean ridges.
Research about the seafloor in the second half of the 1900s, particularly the discovery of mid-ocean ridges and magnetic striping patterns, provided strong evidence supporting the theory of plate tectonics. This new understanding of the seafloor helped scientists realize that the seafloor was spreading at mid-ocean ridges, leading to the acceptance of continental drift as part of the larger theory of plate tectonics.
Earthquake patterns were used to provide evidence of seafloor spreading through the discovery of mid-ocean ridges. Scientists observed that earthquakes were concentrated along these ridges, indicating the presence of tectonic activity associated with the movement of tectonic plates. This supported the theory of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges and pushes older crust away from the ridge.
The rate of seafloor spreading can be calculated by measuring how far tectonic plates have moved apart over a certain time period. This is typically done using techniques like satellite monitoring, GPS, or studying magnetic stripes on the ocean floor. By dividing the distance of spreading by the time it took to occur, scientists can determine the rate of seafloor spreading in centimeters per year.

dumb question. don't want to write it all
Drill cores from the ocean floor were dated and found to be very young compared to the age of the earth. This means the crust had to be formed recently, which can be explained by creation of crust at a spreading center.
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.
The name of the research vessel that was used in proving the seaflor spreading was the vessel Pioneer. It is a marine magnetometer. mikee...=)
They proved that the seafloor was spreading.
1) seafloor spreading 2) continental drift 3 i only found 2
A diagram that shows how seafloor spreading works.
Seafloor spreading is triggered by a rift in a continental land mass.
Gravity in the oceanic crust is responsible for seafloor spreading.
Scientists indicated that the seafloor was spreading, so the poles "reverse"
The Glomar Challenger ship recorded various types of data on magnetic anomalies in the Earth's crust, including magnetic field strength and direction. This information helped scientists study the Earth's magnetic history and map the ocean floor. The data collected by the Glomar Challenger significantly contributed to advancements in understanding plate tectonics and seafloor spreading.
