Sub-Saharan Africa's equatorial area is known as Equatorial Africa. There are 13-14 nations, so I'm guessing you want Ethiopia, Rwanda, Kenya, and Somalia, which are the most well-known. Savannas in the north and south, as well as mountains and tropical rain forests, characterize the landscape.
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.

1 is Improving knowledge of other cultures
The conflicts in Xinjiang, Chechnya, and Quebec all have to do with the desire to become a sovereign state.
Most people in Quebec feel threatened that the unique French culture found there would become assimilated with the Anglospheric culture found in the rest of Canada.
Xinjiang is inhabited primarily by the Uygurs, a Turkic ethnic group. Separatists believe that the region did not belong to China to begin with, even though it was illegally occupied in 1949.
Chechnya is in a state of Russian occupation and independence, which goes back from the dissolution of the Soviet Union.
