all mountain ranges of Himalayas are not snow-covered why?
Answers
Explanation:
- This is because, high altitude regions are always covered in snow, while lower altitudes, on an average, do not receive much snow. Only areas located between the height of 3900 m and 5100 m showed substantial seasonal changes in snow cover area.
Answer:
The climatic snow line is the boundary between a snow-covered and snow-free surface. The actual snow line may adjust seasonally, and be either significantly higher in elevation, or lower. The permanent snow line is the level above which snow will lie all year.
This is a sketch that depicts the various snow lines for the highest peaks in the world.
There is also something called the Glacier equilibrium line.
Normally, mountains that have a permanent snow line will often have a glacier equilibrium line.
The mountains near me, the Smokey Mountains, don’t normally have a snow line, or even a permanent one. However, it can accumulate lots of snow, and be snowy white even when the valley west of it…the Tennessee Valley, has no snow at all. I’ve even seen the snow fall in April in the Smokeys, allowing it to be cold enough to have snow fall to large depths…but the surrounding valley is still bare, and be warm enough for shorts and T-shirts.
To give you an idea. Note the trees below the snow line still having their leaves and looking like autumn is just getting started. But when you go up to the higher elevation, the trees start looking more like late autumn, early winter. And then, you get to the top part and there’s snow.
The Smokeys give the illusion of a snow line, despite not really having one. When I say illusion, I mean…it’s not counted to have one, but still shows the traits of a snow line.
