Question

The thick masses of snow that can create big avalanches accumulate because:

a) of Global Warming
b) of Melting Ice
c) of Snow Compaction
d) of Snow Accumulation

Answer 1

The thick masses of snow that lead to large avalanches accumulate due to snow accumulation, as successive snowfalls build up over time.So the correct option is d.

Step-by-step explanation:

The accumulation of thick snow masses conducive to significant avalanches primarily occurs due to snow accumulation.

This process involves successive layers of snow piling up over time.

As snowfall adds layers, the weight and pressure compress lower layers, leading to snow compaction.

This compaction, facilitated by gravity and temperature fluctuations, transforms loose snow into denser, cohesive masses.

Global warming or melting ice can influence snowpack stability, but they aren't direct causes of snow accumulation for avalanches.

Instead, it's the gradual buildup of snow layers, often on steep slopes, that sets the stage for avalanches.

The interplay between snow accumulation, compaction, and external factors determines the potential for these dangerous events in mountainous regions.

So the correct option is d.
