Question

which is one factor that affects the type of cloud that will form?
altitude
wind direction
color of clouds
size of ice pellets

Explanation:

Clouds are classified based on their shape and height. Altitude plays a crucial role in determining the type of cloud. For example, low - level clouds (below 2000 meters) are different from high - level clouds (above 6000 meters). Wind direction mainly affects the movement of clouds, not their formation type. The color of clouds is a result of how light scatters and is not a factor in cloud formation type. The size of ice pellets is related to precipitation within clouds, not the initial cloud - forming process.

Answer:

altitude
