Answer:
to provide a reference system
Explanation:
The equator and prim meridian used on maps provides a reference system for determining location and navigating the earth.
- An equator is the only line of latitude that is a great circle.
- Prime meridian is a line of longitude that is 0°
- When both are used, they can form the basis of a reference system to determine places on earth.
- Using these lines, we can assign values of coordinates to the earth surface to facilitate location determination.
The equator and prime meridian are used on maps to provide a reference system.

Glaciers shaped the landscape is the answer. Actually, in Nova Scotia near Halifax there is a glacial boulder or erratic of basalt which is deemed to come from about 130km away perhaps from the north or NW. Also, there are glacial striations there on the bedrock which can be used to determine the sense of the direction of flow of the ice. In New England, there are pro-glacial lakes. Both the Maritimes and New England were most likely covered by the Laurentide continental glaciation.
The following which would best categorize Canada's population is concentrated in the south. The three big cities are actually all within under a five-hour distance from the border of the United States (Montreal, Toronto and Vancouver). Cities in Canada are often concentrated in the southern part, because the further north you go, the colder it gets and the cold can often be quite brutal in Northern Canada.
