The sedimentary rock in question is sandstone.
Sandstone is a clastic sedimentary rock made up mostly of weathering sand size debris that accumulates where the waters are slower.
Sandstone is formed by all of the processes named above.
-weathering of the rocks
-erosion caused by water and wind
-transportation by water bodies
-deposition by the water masses where they are slower
-lithification under the pressure
-compactation while mixing with multiple other sediments.

Answer:
a. visible
d. Gamma ray
Explanation:
Gamma rays is the radiations that arise by atomic decay. The molecules for electro magnet waves which are then converted into gamma rays. The energy that is created by molecules cannot be destroyed. It is absorbed by protons and then CO2 molecule become visible.
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>
