Which of the following has the greatest effect on the formation of rain or snow?
A)cloud cover C)air pressure
B)humidity D)temperature
My answer is C) am i right, if not please tell me what you got.
I would think D). Snow can only form if the temperature is below freezing. Otherwise, rain falls.
Air pressure is temperature, Jennifer
Why is the answer c lidia?
At the beginning of a snowstorm, Ashley had 7 inches of snow on her lawn. The snow then began to fall at a constant rate of 3 inches per hour. Assuming no snow was melting, how much snow would Ashley have on her lawn 3 hours after the snow began to fall? How much snow would Ashley have on her lawn after tt hours of snow falling?
To determine which factor has the greatest effect on the formation of rain or snow from the given options (cloud cover, humidity, air pressure, and temperature), we must consider the process behind the formation of precipitation.
Precipitation occurs when moisture in the air condenses into water droplets or ice crystals and falls to the ground. Essentially, it involves the transformation of water vapor into liquid or solid form.
Out of the given options, humidity is directly related to the presence of water vapor in the air. Thus, it has a significant influence on the formation of precipitation. High humidity indicates that there is more water vapor available in the atmosphere, which can eventually condense and form rain or snow.
While cloud cover is associated with the presence of clouds, which are the visible manifestation of water droplets or ice crystals condensed in the air, it is indirectly related to the formation of rain or snow. Cloud cover implies that there is a higher chance of condensation occurring, leading to the formation of precipitation. However, it is the humidity that determines the amount of moisture available for condensation.
Air pressure does impact weather patterns but does not have a direct effect on precipitation formation. Changes in air pressure can influence wind flow and weather systems, which, in turn, can affect the availability of moisture and the conditions suitable for precipitation. However, it does not determine the actual formation of rain or snow.
Similarly, temperature also plays a role in precipitation formation, but its effect is more indirect. Lower temperatures are favorable for the condensation of water vapor into ice crystals, leading to the formation of snow. Higher temperatures, on the other hand, favor the condensation of water vapor into liquid droplets, resulting in rain. However, it is primarily the presence of moisture (humidity) that determines if precipitation will occur, and the temperature dictates the form it takes.
To answer your question, while air pressure, cloud cover, and temperature can influence precipitation formation, the factor with the greatest effect is humidity (option B).
