Answer:
Explanation:
Alberta's oil sands were formed millions of years ago, as tiny marine creatures died and drifted to the sea floor and were covered by layers of sediment that exerted enough pressure and temperatures to transform the organic matter into oil. Over millions of years, that oil became trapped in thick layers of sand.
Coastlines can convert back and forth among various coastal environments due to plate tectonic processes which can cause the land to rise/sink and sea level to increase/decrease: True.
- Plate tectonic is nothing but a process were both continental and oceanic plates starts drifting and converge or diverge with each other.
due to convergence of plate various landforms are formed such as Oceanic tench, fold mountains, volcanoes, etc .
- convrgence could occur between continent-continent , continent-ocean-ocean an continent-ocean plates.
due to divergence of plate boundaries multiple landforms are formed such as volcanoes , mid oceanic ridge , faulting, etc
due to folding and faulting nature, land gets rise or sink.

True. This is an accepted area of topography and geography.
It depends on the latitude where you measure it.
It's about 69 miles on the equator, and it shrinks to zero at the poles.
In general, at any latitude,
Distance covered by 1 degree of longitude =
<em> (69 miles) x [ cosine(latitude where it's measured) ]</em>
