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.
How did Alfred Wegener prove that pangaea existed?
Alfred Wegener proposed the theory of Pangaea based on the fit of the continents, similarities in rock formations, and fossil evidence across continents. He also noted similarities in geological structures and climate data that suggested the continents were once connected before drifting apart. However, Wegener's theory was not widely accepted until much later when additional evidence and advancements in plate tectonics supported his ideas.
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.
Is this a run-on or comma splice by the 1970s scientists have accepted the idea of moving continents today geologists refer to this movement as a plate tectonics.?
This is a run-on sentence because two independent clauses ("By the 1970s scientists have accepted the idea of moving continents" and "Today geologists refer to this movement as plate tectonics") are connected without proper punctuation or conjunction. To correct it, you could separate the clauses into two sentences or use a semicolon to connect them.
Why did Wegener's idea get rejected by scientists?
Scientist rejected Wegners hypothesis of continental drift at first because he did not have enogh evidence to support his theory. He failed to provide a suitable mechanism that could cause the continents to move.
What did scientists discover that showed that continents could move?
Scientist discovered tectonic plates
What do the glossopteris fossils tells us about the early position of the continents?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.
What model developed so that scientists could explain that the continents have moved over millions of year?
Plate Techtonics
What do scientists believe happened to most ancient species?
Their environment changed and they could no longer survive.
Wegener's continental drift hypothesis was weakened because a viable mechanism for moving the continents was lacking?
Yes, they could not find a reason that would cause the movements of the continents. Now, scientists have discovered that the continents don't drift, but rather they are carried by tectonic plates.
What do the glossopteris fossils tell us about early positions of the continents?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.

Why the continents could not possibly move the way wegnener is describing?
During Wegener's time, the mechanism for how continents could move was not understood. Without knowing about plate tectonics, scientists found it hard to believe that continents could plow through the dense oceanic crust. Additionally, Wegener lacked concrete evidence to support his theory, making it challenging for others to accept his ideas.
What do the glossopteris fossils tell us about the early position of the continents?
shows that all three continents were once connected (joined) together. because the 'exact' same fossil types were found in all three different continents, which are now split from each other.
Could all the continents fit into the pacific ocean?
All the continents could fit into the Pacificbasin.
Why has the proper hand position on the steering wheel changed in the last 15 years?
The proper hand position on the steering wheel used to be 10 and 2 but it has changed and is now 9 and 3. I am not 100% why it changed but I believe it changed so you could have a better grip on the steering wheel.Part of the reason for the change was to have your arms out of the way of the airbag.
