The Canadian Shield refers to the exposed portion of the continental crust underlying North America. The crust, also known as the North American Craton, consists of rock from the Archean and Proterozoic eons and extends from Mexico to Greenland. The Canadian portion runs from central Ontario<span> north to the </span>Arctic Archipelago, and fromLabrador<span> west to the </span>Northwest Territories<span>. The Shield includes some of the oldest rocks on Earth (possibly more than 4 billion years old). While at times a barrier to settlement, the Shield has also yielded great resources, including </span>minerals<span>, </span>coniferous forests<span> and the capacity for</span>hydroelectric<span> developments.</span>
Answer:
velocity = 7.30 m/sec
23 m depth wave will feel bottom
Explanation:
given data
wavelength = 46 meters
wave period = 6.3 second
to find out
velocity and At what water depth will a deep water wave begin to feel bottom
solution
we get here velocity that is express as
velocity = 
.............1
velocity = 
velocity = 7.30 m/sec
and
wave base = 
× wavelength .................2
wave base = × 46
wave base = 23 m
here water depth more than 23 m will producer will circular wave less than elliptical wave
so 23 m depth wave will feel bottom
Answer:
<u>B) Tropical wet and dry</u>
Explanation:
I had this question
if I'm wrong let me know
Answer:
Water was necessary for growing crops.
The rivers provided transportation.
The seas allowed for trade with other civilizations.
Water was needed for raising animals.
Explanation:
All mentioned option except Water provided power for electricity are correct because of the simple reason that the electricity didn't existed in the 4th millennium BC when this first settlements were created. This settlements were created in the area between Egypt and Mesopotamia in the shape of crescent, thus we have that name. Of course, they needed water to crop, as agriculture was widespread, but the seas also allowed them trade, especially between Egypt and Mesopotamia.
