Quebecois French is b) diverged from Parisian French. However, this is only historically speaking and only pertains to the 17th century "koine" of Paris. Nowadays, the distinction between French from France and French from Quebec is huge and the accent stands out very strong compared to other dialects of French. However, the Quebecois are very proud of their language and do not want to standardize, as they feel it would be a removal of their culture.
Isostatic rebound occurs when a load is imposed on or removed from the lithosphere. The surface tends to rise or sink as the lithosphere rises or sinks in the asthenosphere. Loads may consist of large lakes, oceans (on continental shelves during eustatic sea level rise), ice, sediment, thrust sheets, and volcanoes.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
A gravel covered plain is called a Reg. A reg is a desert basin where the sand has been blown away leaving a gravel covered plain.
