sammy [17]

Answer:

By looking at the map we can infer that A) Manufacturing was a key part of the economy in the Northeast.

Explanation:

Most of the technology was brought over from England and as people started to settle they started to work with cotton and manufacturing textiles. It is true that being close to a body of water made it easier not only to transport the goods but also the machinery needed. However, Illinois and Indiana have Lake Michigan as a primary body of water. We know that textiles were a big part of the economy since very early on and so were cotton fields, were they would extract the necessary material to them manufacture the textiles needed.

What was the result of geologists trying to disprove the idea that the continents were all once together as once land mass by te
hichkok12 [17]

Answer:

B.Mineral and fossils matched on separate continents adding evidence in support of Wegener’s theory.

Explanation:

    Theory created by the German meteorologist Alfred Wegener, in which he stated that approximately 200 million years ago there was no separation between continents, ie there was a single continental mass called Pangeia and a single ocean, the Pantalassa.

    After millions of years there was a fragmentation emerging two megacontinents called Laurasia and Godwana, and from there the continents were moving and adapting to the current configurations.

    The crucial point for the development of the Continental Drift theory, which in its essence means the movement of continents, or moving plates, is the realization that the earth is not static. Then Wegener realized that the coast of Africa was contoured that fit the coast of South America.

   Another trace that supports the theory was the discovery of fossils of animals of the same species on different continents, as it would be impossible for these animals to have crossed the Atlantic Ocean, the only explanation being that in the past the two continents were together.
