The answer is coal
non renewable means it will end up depleted
1. Galaxies seem to be moving away from us which can support Big Bang Theory.
2. The abundance of Helium and Hydrodgen also support the Big Bang theory!
Personlly I do not believe in the big bang theory but if you need more reasons please comment! :-)
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: Option (A) and (C)
Explanation: In case of slow sea floor spreading, the magma within the crust doesn't get proper way to exert the force upward because of its slower rate of spreading. Due to this, rifting occurs along the mid oceanic ridge.
Due to continuous rifting, it forms a valley known as the rift valley. This rift valley lacks in ridge and is comparatively smooth compared to a fast spreading sea floor, in which the topography appears to be rough and ridges are formed.
Thus, the statements that are true are option (A) and (C).
