1. the coastlines of continents fitting together like puzzle pieces was one of the four pieces of evidence for continental drift. true or false? 2.why was wegners theory of continental drift not accepted by the scientific community? a. he had no friends in the community b. he could not explain how the continents moved c. his suggestion of land bridges was not accepted d. he could not explain why the coastlines fit together like puzzle pieces

The statement in #1 is true, but that's NOT the way Science works.  Scientists DON'T dream up a theory and then go out looking for evidence to support it. A MUCH better, more accurate way to say it is:  "The theory of Continental Drift was a very successful explanation for the coastlines of continents fitting together like puzzle pieces, and also for three other observations."

#2). b

he . if i may ask what i your question exactly?

explanation:

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
