Step-by-step explanation:
The resource located at 65°N, 90°W is freshwater. This location falls within the boundaries of the vast Canadian Shield, which possesses abundant freshwater resources, including an extensive network of lakes and rivers. Given the list of resources provided and the specific coordinates, the correct answer to what resource is found there would be freshwater, encompassing both surface and groundwater resources.
