In the 1960s, scientists discovered a central rift valley along the mid-ocean ridge system. This valley is an underwater depression that forms at the crest of a ridge where tectonic plates are moving apart. Here, new oceanic crust is created through volcanic activity, providing important insights into the process of seafloor spreading and plate tectonics.

Was the theory of a'super continent' originally accepted by scientists?
No, the theory of a supercontinent was initially met with skepticism by scientists when it was proposed by Alfred Wegener in the early 20th century. It was not widely accepted until the 1960s, when advancements in plate tectonics provided more evidence to support the idea.
How did scientists advance Wagner's Hypothesis into the Theory of plate Tectonics?
Scientists used new technologies such as seafloor mapping, paleomagnetism, and seismic studies to gather extensive evidence supporting the movement of tectonic plates. These observations revealed a pattern of seafloor spreading, subduction zones, and continental drift, leading to the development of the Theory of Plate Tectonics in the 1960s.
Who were the two scientists who proposed the theory of sea floor spreading in the early 1960's?
The two scientists who proposed the theory of sea floor spreading in the early 1960s were Harry Hess and Robert Dietz. They presented the idea that new oceanic crust is formed at mid-ocean ridges and then moves away from the ridges, eventually sinking back into the mantle at subduction zones.
What discovery caused scientists to rethink wegeners continental drift theory?
The discovery of mid-ocean ridges and the process of seafloor spreading in the 1960s caused scientists to rethink Wegener's theory of continental drift. This new evidence provided a mechanism for how continents could move apart and lent support to the concept of plate tectonics as the driving force behind the movement of Earth's lithospheric plates.
Why did most scientists reject Wegener's theory for hat for nearly a half century?
Most scientists rejected Wegener's theory of continental drift because he lacked a plausible mechanism to explain how continents could move. Additionally, his theory did not align with the dominant geological beliefs of the time, and there was a lack of concrete evidence to support his ideas. It was only with the development of the theory of plate tectonics in the 1960s that Wegener's ideas gained widespread acceptance.

In the 1950s and 1960s what was the main part of a computer?

What is polywater?
In the 1960s, scientists thought that water could exist as a polymer. It was called "Polywater", and became a very popular thing to talk about. Unfortunately, by 1973 scientists concluded that there was no such thing as polywater.
Name two regions in different parts of the world where the green revolution has had a significant impact on crop yields?
Punjab, India: The green revolution in the 1960s significantly increased crop yields through the adoption of high-yielding varieties of wheat and rice, along with modern agricultural practices. Central Valley, California, USA: The green revolution in the 20th century led to increased crop yields in the Central Valley through the introduction of new technologies, irrigation systems, and crop varieties.
Who invented the glow stick?
The glow stick was invented by a combination of American scientists Herbert Richter and Ruth Tedrick in the 1960s. They were looking for a safer way to provide light without the use of batteries or electricity.
Can sassafras cause cancer?
In the 1960s scientists determined that the volatile oil derived from sassafras root contains safrole as its chief component. Safrole is a known carcinogen in animal studies.
Was the theory of a'super continent' originally accepted by scientists?
No, the theory of a supercontinent was initially met with skepticism by scientists when it was proposed by Alfred Wegener in the early 20th century. It was not widely accepted until the 1960s, when advancements in plate tectonics provided more evidence to support the idea.
When was garamycin discovered?
Garamycin, also known as gentamicin, was discovered in the 1960s by scientists at Schering Corporation (now part of Merck & Co.). It was first isolated from the soil bacterium Micromonospora purpurea.
What are three reasons for conflict in Central America?
1. uneven distribution of land 2. wealth has led to many uprisings 3. disputes in Central America since the 1960s 4. Government issues
