True, A 'planar projection map' is helpful for sea navigation.
<u>Explanation:
</u>
A 'planar projection map' that shows the particulars of the globe in a flat surface projection. The pictures projected by the map are shown in rectangular-shaped. If any other map such as Cylindrical map is used then, the edges are not so perfect, they show distortion. With the help of all three coordinates, it shows a 3-D picture of the globe and its objects which can be considered almost as real as the actual object. They are also known as azimuthal projections and are mostly used in projecting polar regions.

In 1998, Canada's highest court declared that Quebec could not legally secede.
Explanation:
Canada is the second largest country in the world. In order for the vast territory to be easier for governing, Canada is divided into provinces and territories. Such provinces and territories in Canada are:
- Quebec
- Ontario
- Alberta
- Manitoba
- British Columbia
- Saskatchewan etc.
While most of the provinces and territories have nothing against being in the borders of Canada, there is one that opposes it, that being Quebec. Quebec is one of the provinces that contributes the most to the GDP of the country, is one of the most populous, and has an excellent location.
This province doesn't want to be in the borders of Canada though, but instead wants to be independent. The main reasons for that are that the majority of the people of Quebec have different ethnic and cultural background than the rest of the provinces and territories. While the people of Quebec already had several referendums about independence, with the majority of the population voting for it, the Canadian highest court declared any attempts for seceding of Quebec illegal in 1998.
