Question

(A) Precipitation in the form of solid particles of snow
(B) Precipitation in the form of liquid particles of snow
(C) Precipitation in the form of temperature
(D) All of the above

Answer 1

Hint: Main snow-prone expenses include the polar areas, the northernmost half of the Northern Hemisphere and precipitous areas universal with adequate humidity and cold temperatures. In the Southern Hemisphere, snow is limited mainly to hilly expanses, apart from Antarctica.

Complete answer:
Snow includes discrete ice crystals that cultivate while hovering in the atmosphere—typically within clouds—and then descent, amassing on the ground where they experience additional vicissitudes. It comprises frozen crystalline water during its life cycle, beginning when, under appropriate circumstances, the ice crystals mould in the atmosphere, upsurge to millimetre size, fall and amass on exteriors, then transform in place, and eventually melt, slide or channel away. Snowstorms establish and grow by alimentation on sources of atmospheric humidity and cold air. Snowflakes nucleate around elements in the atmosphere by enticing supercooled water condensations, which solidify in hexagonal-shaped crystals. Snowflakes take on a diversity of forms, rudimentary among these are platelets, needles, columns and frost. As snow amasses into a snowpack, it may waft into glides.

Thus, option (A) is correct.

Note: Snow clouds typically occur in the framework of bigger weather systems, the most significant of which is the low-pressure expanse, which classically integrates warm and cold fronts as part of their movement. 2 supplementary and locally prolific sources of snow are lake- consequence (also sea- consequence) storms and raise consequences, particularly in mountains.
