Question

4 fill in the blanks to complete the sentences. ice crystals form when the water vapor in blank solidifies. all snow crystals get their blank shape from the arrangement of water blank when they freeze. the rate at which an ice crystal grows depends on the blank in which it forms, while its blank depends on the level of humidity. (word options: complexity, molecules, symmetrical, clouds, temperature)

Explanation:

Sentence 1:

To determine the first blank, we know that water vapor is present in clouds, and when it solidifies, ice crystals form. So the first blank should be "clouds".

Sentence 2:

For the second sentence, snow crystals typically have a symmetrical shape, and this shape comes from the arrangement of water molecules when they freeze. So the first blank here is "symmetrical" and the second is "molecules".

Sentence 3:

In the third sentence, the rate of ice crystal growth depends on the temperature (the condition it forms in), and its complexity (the intricacy of its structure) depends on humidity. So the first blank is "temperature" and the second is "complexity".

Filled Sentences:

1. Ice crystals form when the water vapor in $\boldsymbol{\text{clouds}}$ solidifies.
2. All snow crystals get their $\boldsymbol{\text{symmetrical}}$ shape from the arrangement of water $\boldsymbol{\text{molecules}}$ when they freeze.
3. The rate at which an ice crystal grows depends on the $\boldsymbol{\text{temperature}}$ in which it forms, while its $\boldsymbol{\text{complexity}}$ depends on the level of humidity.

Answer:

s (Blanks in Order):

1. clouds
2. symmetrical, molecules
3. temperature, complexity
