The first part is true. second part is false. so whole statement is false
False
Answer:
The Rocky Mountains are a push factor.
Explanation:
There are numerous factors that contribute to migration, but all of them can be put in two wide categories, push factors and pull factors. The push factors are the factors that make people leave a certain place and move to another one. The pull factors are the factors that attract people to move into a certain place.
The Rocky Mountains can be considered as a push factor. The reason for this is that these mountains when compared to many other parts of the United States, offer very few opportunities and advantages. Especially when the large economic centers are taken into consideration, being in the same country, people naturally feel that they are missing out on a lot of things in life by living in the Rocky Mountains, so they move out of them and generally tend to migrate to the big urban areas.
From almost the creation of the first true maps of the Earth, people started seeing how continents would be able to fit together. In particular, people noticed that South America fits almost exactly into Africa.
You should be aware that while world maps were around early in the 1600’s and better defined by the end of the 1700’s, those maps were not ‘public’ but were treated as state secrets. And so it was not till much later that the broader ‘science’ community had access to good quality and accurate world maps.
It is now known that most of the major continental masses can be fit together in a jigsaw process. In fact we now know that the continents were indeed once all joined together as one land mass – the super-continent of Pangaea.
If you look at most world maps you will ponder how this is evidence, as the continents really don’t appear to ‘fit’ together very well. What you need to understand is that the vast majority of maps are drawn using a map projection that has the north and south poles (which are points) are a line the width of the map at the top and bottom. This means that the map distorts the true shape of the Earth’s land and oceans as you love closer to the poles. Some other map projections distort less, but have the map shape looking like segments of an orange. See here for a range of map projections. Check out the way Greenland changes size in each!
