What scientist advance the hypothesis of continental drift in the early 1900s?
Alfred Wegener
What scientist advanced the hypothesis of continental drift in the early 1900s?
Alfred Wegener
Who was the scientist who contributed to the plate tectonics theory?
A man named Alfred Wegener first put out the theory of continental drift. That theory then evolved into sea floor spreading when a man named Harry Hess discovered that there are underwater mountain ranges spreading laterally away from them. That then arrives at the current theory of plate tectonics.
What do geologists know today that would have convinced geologists of the early 1900s that Alfred Wegeners theory of contintental drift was in part correct?
They know that the continents drifted to their current location due to the rotation of the Earth.
Who conducted stratigraphic excavations at Pecos Pueblo in North Central New Mexico in the early 1900s?
Alfred Kidder
Who composed what is known as the big bag theory?
Fred Hoyle is the one that is credited for coining the phrase The Big Bang Theory. The theory itself was first composed from observed by Vestro Slipher in the early 1900s.
Why was the theory of the of the atom so controversial in the early 1900s?
Complicate and new theories are continuously controversial; but this controverse is the source of progress in knowledge.
Why was wegeners theory ignored until the mid 1960s?
Alfred Wegener tried to explain how continental drift took place, but he had no concrete evidence about how the continents moved. He had to explain what force is pushing and pulling the continents. And mainly in the early 1900s, most geologists thought that mountains formed because Earth was slowly cooling and shrinking. So most geologists would have to change their ideas of how mountains formed. Then in 1960 Harry Hess, an American geologist, he thought about the ocean floor in relation to the problem of continental drift. He proposed a process called sea-floor spreading. In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. The ocean floors move like conveyor belts, carrying the continents with them. Hess soon found evidence from molten material, magnetic stripes, and rock samples from the mid-ocean ridges. And he proved that Wegener's theory wasn't wrong.
When was the first atomic theory and the theory of relativity first proposed?
1900Atomic theory: Leucippus (approx. 500 BC) and Democritus (approx. 460-370 BC).Theory of relativity:* special relativity - Albert Einstein, 1905* general relativity - Albert Einstein, 1916

Was the first cellular telephone tested in the 1900s or the 1800s?
1900s
Which lines of evidence did Wegener used to argue continental drift in the early 1900s?
- glaciation similarities - plant and animal fossils located at different areas of the earth.suggesting that one continent must've been closer to another at one point.- same age and types of rocks- jigsaw puzzle of the earth.
