Where can clouds form?

Question

A low altitudes in the troposphere

B high altitudes in the troposphere

C any altitude in the troposphere

D any altitude in the ionosphere

Answer 1

Well, I believe the answer is C, and nacreous clouds are often observed in the stratosphere. Thunderstorm overshooting tops are often pushed into the stratosphere but are not formed there.

Answer 2

the answer is c.

Answer 3

The answer is 'C'.Troposphere only contains moisture and the moisture content is not constant throughout the troposphere and varies with height and hence cloud can form at any height within the troposphere.

Answer 4

this is a school question isn't it?

haha

Answer 5

Three things are needed for the formation of clouds.  

1. Condensation Nuclei (dust, salt etc...).

2. Moisture.

3. Some form of lifting.

All three of these can be found at any altitude within the troposphere.

Answer 6

C: At any altitude providing that conditions of Humidity, Temperature and Pressure are met for the formation of Clouds. (Partial condensation of water vapour to microscopic particles of water held aloft by Thermals rising from the ground).
