Is the analysis of seafoor sediments evidence of sea-floor spreading?
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
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.
When did vascular plants most likely evolve What is the evidence for the time scale?
During the Devonian Period is when vascular plants most likely evolved. The evidence of this time scale is that fossils dating back to the Devonian Period have been found.
How magneteism is used to support the theory of seafloor spreading?
During the Second World War, linear bands of positive and negative magnetic anomolies were found in the ocean floor, stretching for hundreds of miles, with an almost perfect symmetry either side of mid-ocean ridges. It was realised that these anomalies were evidence of periodic reversals of the earth's magnetic field. Molten basalt had been magnetised in the direction of the field and then cooled to 'fossilise' that direction. Each time the earth's magnetic field reversed, a stripe was added to the 'bar-code'. By dating onshore lava flows where magnetic reversals had occurred, a timescale of magnetic reversals was built up. It then became clear that, in the undersea anomalies, the youngest rocks were near the ridge, while the oldest were farther away and nearest the continents. Either side of the ridge, stripes of exactly the same age could be matched with each other. There was already evidence of continental drift, but this new evidence helped to explain how the earth's crust is moving and how the sea floor is spreading.
How does carbon dating prove a young earth?
Carbon-dating can not be used to prove the age of the earth, so it can not be used either to prove a "young earth" nor to support the scientific age of the earth. Carbon-dating is useful for archaeology, where it can date evidence of human artefacts up to fifty thousand years old. Some less less informed "Young Earth" creationists do believe that carbon-dating was used to date the earth. They attempt, unsuccessfully, to undermine the science of carbon-dating in the belief that by doing so they undermine the scientific age of the earth, rather than because they constructively prove their point. The best estimates of the age of the earth have been arrived at by radioactive dating, but not by carbon-dating. Had techniques of radioactive dating not been invented, other known methods of dating the earth would prove that the world is more than a few million years old. Some of these are described in the related question, attached below.
