Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The summers in the tundra are ____
A
Short and cold
B
short and soggy
C
long and cold
D
short and warm
Explanation: 

Detailed explanation-1: -Alpine tundra has a more moderate climate: summers are cool, with temperatures that range from 3 to 12 °C (37 to 54 °F), and winters are moderate, with temperatures that rarely fall below –18 °C (0 °F).

Detailed explanation-2: -The summer growing season is just 50 to 60 days, when the sun shines up to 24 hours a day. The relatively few species of plants and animals that live in the harsh conditions of the tundra are essentially clinging to life.

Detailed explanation-3: -The tundra seems like a wet and soggy place because the precipitation that falls evaporates slowly, and because of the poor drainage caused by the permafrost. You can find the tundra climate in Köppen’s E climate category. The Estands for ice climates. The average temperature of the warmest month is below 50° F.

Detailed explanation-4: -The growing season in the tundra is very short, usually only 6 to 10 weeks. In the summer, the top layer of soil may thaw out. When the ice melts, it can’t drain into the soil because of the permafrost, so water collects in bogs and ponds. This makes up for the low rain and snowfall!
