1. What made scientist believe that the seafloor was spreading?
Samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge.
Also, the rock making up the ocean floor is considerably younger than the continents, with no samples found over 200 million years old, as contrasted with maximum ages of over 3 billion years for the continental rocks.
This confirms that older ocean crust has been reabsorbed in ocean trench systems.

Scientists believe that this layer of the Earth is made of hot liquid iron and nickel?
The outer core.
How does ocean floor spreading relate to plate tectonics and continental drift?
The connection is that the ocean floor spreading is what causes the subduction. When the steadily enlarging ocean floor meets a continental plate it slides under it. That's what subduction means.
Do scientists believe that the thinning of the ozone since the 1970's is a naturally occurring phenomenon or human induced?
They believed it was man made. It was because of CFC's.
When was The Floor Is Made of Lava created?
The Floor Is Made of Lava was created in 2006.
What made the climate of northern Africa change from tropical to grasslands and then to desert?
Most scientists believe that the Sahara in Northern Africa changed from grasslands to desert due to a change in the Earth's orbit.

What made scientists accept Alfred wegener theory years later?
Accumulating data, especially proof of sea floor spreading.
What a spreading center and what is made at one?
Sea floor spreading 2 oceanic plates coming apart
What is the relationship between platetectonics and seafloor spreading?
Plate tectonics is the theory that earth is made of plates that move slowly. Sea floor spreading is related to this because the split created in the sea floor is created by the plates moving apart.
What is the difference between subduction and seafloor spreading?
Sea floor spreading is where new oceanic crust is formed through volcanic activity and then moves away from the ridge. Subduction is when one tectonic plate moves under another tectonic plate. Hope this helped :)
How do you use canard in a sentence like spreading rumour?
The canard made everybody believe that me and riya are in a relation.
Who designed a first elavator that made it possible for people to move easily from floor to floor in a skyscraper?
I do believe that it was Elisha Otis
Does sea-floor spreading increase the diameter of the earth?
No. While new sea floor is being made in one place, at other places it is being destroyed, the diameter of the earth therefore remains constant overall.
Scientists believe that this layer of the Earth is made of hot liquid iron and nickel?
The outer core.
Which layer of Earth do scientists believe is most likely made of solid metals?
The inner core.
Who was the person that that made a hypothesis of continental drift?
It was Alfred Wegener but other scientists did not believe him but he found evidence
