Final answer:
The mountain range in Suriname that extends into neighboring countries is part of the Guiana Highlands, which are notable for their geographic and economic importance due to natural resources.
Step-by-step explanation:
The mountain range that covers most of Suriname and extends into Guyana, Brazil, and French Guiana includes the Wilhelmina Mountains, De Haan Mountains, and Van Asch Van Wijck Mountains. These mountains are part of the Guiana Highlands, which are known for their rugged landscapes and tropical climate.
The Guiana Highlands are not only geographically significant but also historically and economically important due to the presence of natural resources that have led to border disputes among these countries. Suriname, formerly known as Dutch Guiana, gained independence in 1975, and since then, the country has been developing its natural resources like bauxite, gold mining, and oil extraction to strengthen its economy while also actively working to preserve its natural environment through national parks and UNESCO world heritage sites.
