Precipitation and Ice Formation Concepts

What role do condensation nuclei play in cloud formation?

• They prevent clouds from forming.

• They absorb water vapor.

• They repel water droplets.

• They initiate the condensation process.

What is the Bergeron process primarily associated with?

• Formation of rain

• Formation of snow

• Formation of fog

• Formation of hail

What is supercooled water?

• Water that is above its boiling point

• Water that is below its freezing point but still liquid

• Water that is at room temperature

• Water that is frozen solid

How does supercooled water solidify?

• By adding salt

• By disturbing it

• By leaving it undisturbed

• By heating it

In the Bergeron process, what happens to ice crystals?

• They remain unchanged.

• They melt immediately.

• They grow at the expense of supercooled water.

• They shrink as they absorb water vapor.

What does supersaturation mean in the context of the Bergeron process?

• Air has no water vapor.

• Air has less water vapor than it can hold.

• Air is at its maximum temperature.

• Air has more water vapor than it can hold.

What happens to snowflakes as they fall through warmer air?

• They evaporate.

• They grow larger.

• They turn into rain.

• They freeze further.

What is accretion in the context of snowflakes?

• Snowflakes sticking together

• Snowflakes evaporating

• Snowflakes melting

• Snowflakes breaking apart

How does temperature inversion affect precipitation?

• It causes snow to evaporate.

• It has no effect on precipitation.

• It causes snow to fall as rain.

• It causes rain to freeze.

What determines whether precipitation falls as snow or rain?

• The time of day

• The speed of the wind

• The temperature of the air

• The size of the cloud
