Which is one factor that will affect the type of cloud that will form? -altitude. -wind direction. - color of clouds. - size of pellets

altitude.

Explanation:

As air rises in the atmosphere, it becomes cool because air pressure is less at that altitude. So, when the air cools to a certain degree, it is unable to hold the water vapor and this vapor becomes water droplets and thus, cloud is formed.

Other factors also influence cloud formation such as topography, humidity, etc but according to the question and with regards to the options available, the correct answer is altitude.

altitude

Explanation:

Altitude is responsible for the formation of different types of clouds. There are three types of clouds on the basis of altitude i. e. low level clouds such as cumulus, stratus etc which are present at the height below  6,500 feet, the middle level clouds such as altocumulus and nimbostratus etc which are present between 6,500 and 20,000 feet and high level clouds such as cirrus, cirrocumulus etc that is present above 20,000 feet.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
