Answer 1

1. Tundra is located at the top of the world, near the north pole. Tundra is a Finnish word which means barren land. Thus, the Tundra region having the least vegetation and polar or arctic climate is found in North America and Eurasia between the southern limit of the permanent ice caps in the north and the northern limit of the temperate coniferous forest of taiga climate in the south.
2. In Barrow, the warmest month is July while the lowest temperature is in the month of February. The same temperature conditions are observed in Barentsburg.
3. The average annual range of temperature in Barrow is -12.2°C while in Barentsburg it is -5.9° C.
4. This is because the sun's rays are oblique and little insolation is received being at higher latitude -65° to 90° North.
