Scientists now believe that plate tectonics, the movement of Earth's lithosphere plates over the semi-fluid asthenosphere below, is responsible for continental drift. This movement is driven by the convection currents in the mantle, leading to the gradual shifting of continents over millions of years. This theory has been supported by evidence such as the matching Coastlines of continents, distribution of fossils, and rock formations.

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.
What do scientist now think might be a possible cause of continental drifth?
Scientists now believe that the movement of tectonic plates caused by mantle convection could be a possible cause of continental drift. This phenomenon describes how the Earth's crust is broken into large plates that float on the semi-fluid asthenosphere beneath them, causing them to slowly move and shift over time. This movement can result in the continents drifting apart or coming together.
How with so much evidence to support continental drift how could scientists reject the idea?
Some scientists rejected the idea of continental drift because Alfred Wegener, who proposed the theory, lacked a plausible mechanism to explain how continents could move. In addition, the scientific community at the time held onto the prevailing belief in static continents and were resistant to accepting a new paradigm. It wasn't until the development of plate tectonics in the 1960s that continental drift became widely accepted.
At first many scientists rejected Wegener and the hypothesis of continental drift. What was their main objection to his hypothesis?
The main objection to Wegener's hypothesis of continental drift was the lack of a plausible mechanism to explain how continents could move. Wegener's idea of continents plowing through solid oceanic crust was not supported by scientific knowledge at that time, leading many scientists to reject his hypothesis.
What was one question that Alfred wegener could not answer?
One question Alfred Wegener could not answer was the mechanism that caused the movement of continents, as he proposed the theory of continental drift before the discovery of plate tectonics. He could not explain how or why continents would be able to move through solid oceanic crust.
Why did many scientists not accept the early theiories of continental drifts?
Alfred Wegener did not have the "HOW" factor- because of no evidence on the process, they could not believe his theory.
Why was the continental drift rejected by scientists?
yes becouse wenger is not geologist and he could not explain the how continental drift theory

What is the thickest the continental or oceanic?
i believe the continental(granatic)crust is thicker than oceanic(basaltic)crust but i could be wrong
Why was the theory of continental drift not accepted first?
scientists back then didn't want to belive that the earths plates could move on there own
Are porcupines quills poisonous?
No, a porcupine's quills are not poisonous.
Why do you think people didn't believe continental drift?
People did not believe in continental drift initially because the theory lacked a mechanism to explain how continents could move. Additionally, the concept challenged existing ideas about the permanence of the Earth's surface. It wasn't until the development of the theory of plate tectonics in the 1960s that continental drift gained widespread acceptance.
Why did Wagener's theory of continental drift not accepted?
Alfred Wegener's theory of continental drift was not initially accepted because he lacked a mechanism to explain how continents could move. Additionally, his evidence was considered insufficient and geologists at that time did not believe that continents could drift over time. It was not until the theory of plate tectonics was developed in the 1960s that Wegener's ideas gained widespread acceptance.
What did Francis Bacon believe scientist could do?
Believed that scientists should rely on the bible.
Is living thing is possible in Mars?
No, but scientists believe that there could have once been life on Mars.
What do scientists believe happened to most ancient species?
Their environment changed and they could no longer survive.
