📚 Topic Summary
Rain, snow, sleet, and hail are all forms of precipitation, but they differ based on atmospheric temperature profiles. Rain forms when water droplets in clouds become heavy enough to fall to the ground as liquid. Snow forms when the atmospheric temperature is cold enough to turn water vapor into ice crystals. Sleet is a mix of rain and snow, forming when snow melts as it falls through a layer of warmer air and then refreezes as it passes through a layer of cold air near the ground. Hail, on the other hand, forms in thunderstorms when strong updrafts carry raindrops into very cold areas of the atmosphere, where they freeze and accumulate layers of ice.

✍️ Part B: Fill in the Blanks
Complete the following paragraph using the words: temperature, clouds, frozen, layers.
Hail forms within storm _____. Strong updrafts carry raindrops into parts of the atmosphere where the ______ is below freezing. These raindrops collect _____ of ice as they are tossed around. Sleet is rain that has _____ as it falls through a cold layer of air.
(Answers: clouds, temperature, layers, frozen)
🤔 Part C: Critical Thinking
Explain how the temperature profile of the atmosphere affects whether precipitation falls as rain, snow, sleet, or hail. Be specific about the conditions necessary for each type of precipitation.
