Identify and describe the primary geographical features and their locations as indicated by the map and legend. Specifically address Task 1, which involves outlining regions with green, identifying neighboring subjects and states, and marking the Northern Polar Circle with blue.

Task 1: Geographical Features and Boundaries

This task requires a physical interaction with the map (coloring and labeling) which cannot be performed by this tool. However, I can describe the process based on the map's visual information:

• Outline regions with green: This would involve identifying distinct geographical or administrative regions on the map and coloring their boundaries green.
• Label neighboring subjects and states: This requires identifying the names of Russian federal subjects and any adjacent countries that share a border with the highlighted regions. These names would be written directly onto the map.
• Identify neighboring seas and oceans: The map displays bodies of water such as the Arctic Ocean and the Pacific Ocean. These would need to be labeled.
• Outline the Northern Polar Circle with blue: The Northern Polar Circle is a latitudinal line depicted on the map. This line would be colored blue.

General Geographical Information visible on the map: The map displays the physical geography of Russia, including major rivers, mountain ranges, and bodies of water. It also shows the latitudinal and longitudinal grid lines, with key parallels like the Northern Polar Circle clearly marked. The scale indicates that 1 cm on the map represents 200 kilometers.
