The exposed portion of the
continental crust underlying North America refers to Canadian Shield. The continental
crust is known as the North American Craton which consists of rocks from the
Archean dn Proterozoic eons and extends from Mexico to Greenland. Canadian
Shield also produces great resources that helped most humans for their economic
development. Because of the resources present in the Shield, it has a great
disadvantage to settlers. The primary obstacle to population growth in the area
is the presence of the bare rock, thin soils, muskeg and insects.
We can control resource depletion by rationing them and making thing that don't need or use so much resources.
Well, if you look at the ocean from a standing point of view, it's pretty flat and water is spread all around the surface. Because of this, most people would assume that ocean is just flat and smooth.
Thanks to the discovery of science, we're able to go down deep and learn that there is more to the ocean than we knew about. =)

Explanation:
1) Jupiter is a planet made entirely out if gas, therefore humans can't walk on Jupiter and Jupiter lacks oxygen.
2) Uranus is a Ice giant, that means it's very cold and humans would most likely freeze to death. Also Uranus lacks oxogen..
3) Neptune is the farthest known planet from the sun, that makes Neptune too cold to be lived on.
4)Pluto is far from the sun, which would make it very cold
5) Mars would be perfect for humans, but the o-zone lacks of oxygen. Scientists say, Mars could support like if we simulate life on earth. Mars is also humid enough to support life.
