How can vertical temperature affect the form of precipitation?

Correct answer: A warm lower layer can melt snowflakes into rain

Correct answer: D. Precipitation may begin as ice crystals or snow high in a cloud, but its final form depends on the temperature of the air through which it falls. If the air remains below freezing, snow or ice pellets may reach the ground. If the particles pass through a sufficiently warm layer, they can melt and become liquid raindrops. A later cold layer may refreeze them or produce sleet, depending on its depth and temperature. Option D is correct because a warm lower layer can melt falling snowflakes into rain before they reach the surface. Option A is unrelated to precipitation form. Option B is false because temperature controls whether water is solid, liquid or gaseous. Option C is false because rocks do not create rain in this process. Memory cue: follow the particle downward and check each temperature layer.
