I think the answer is B.
Because one of the factors that has prevented it from being a more unified country is its geography. It's rugged, mountainous. It's very difficult for any invading army to develop or control it.
Local shear failure occurs when the shear stresses parallel to the grain, i.e. shear stresses acting in the longitudinal-tangential (LT) or longitudinal-radial (LR) planes, exceed the shear strength of the beam. The shear strength of a wood member is difficult to quantify.
A large part of that land area is not conducive to farming or general use. The Canadian Shield covers about a third of the nation. The Arctic permafrost probably covers another third. You cannot farm in either of these areas and the cost of building roads and infrastructure in or through these areas is very high. Other areas have land that could be used for farming but the season is too short. On the lands that are arable, Canadians are reasonably densely populated.
<span>As to softened immigration process, the percentage of permanent residents (generally recent immigrants) has remained fairly steady at less than or at 1% of the population for at least 50 years. Since the birthrates for multi generational Canadians (Canadians whose grand parents or before were immigrants) is so low, Canada needs immigrants to maintain the population at a sustainable level. Yet the processes have not gotten easier. The most recent iteration of the Immigration act has extended the time required for a landed immigrant to live in Canada before being eligible for citizenship (from three years in five to four years in six).</span>
A i think is the correct answer
Answer:
Igneous and sedimentary rock types led to the formation of terranes as these has occurred during the time of oceanic basin closure.
Explanation:
- The deposition of sedimentary and volcanic rocks and some still unconsolidated sediments are deposited in the region which is related to the terrane accelerated events.
- And terrane acceleration is tectonostratigraphic fragmentation of crustal matter which is often broken from the crustal plate and is identified as a fault.
- Their activity is reflected in igneous rocks when the source material was eroded from the sediments. The youngest ages are constrained by the deposition of schists with active volcanism at its source with the youngest zircon crystallization.
- Diverse types of acceleration may be found in oceanic plateaus, island, and arcs and composite terranes of stratified, disrupted, metamorphic and composite.
