Question

Give a geographical reason:

Vegetation is short-lived in the Tundra region.

Answer 1

1. The winter temperature of the Tundra region is approximately -20 °C to -30 °C. this temperature does not support the growth of vegetation.
2. The mean summer temperature of the Tundra region is 10 °C. 
3. Due to the availability of sunlight, short grass, small shrubs, flowers, lichens, moss, etc. grow in the Tundra region. But, during long winters, the natural vegetation in the Tundra region disappears at rapid speed. Thus, vegetation is short-lived in the Tundra region.
