Answer :
A cloud in a lifting air parcel will likely begin to form at an altitude above 2000 meters, given that low clouds form between the surface and this altitude and mid-level clouds form beyond it. Therefore, the correct answer is option 2) As the parcel moves above 2000 meters
The altitude at which a cloud will begin to form as an air parcel is lifted depends on the atmospheric conditions and moisture content of the air parcel. According to the given reference information, low clouds form between the surface and 2000 meters, mid-level clouds form between 2000 and 7000 meters, and high clouds form above 7000 meters. As air rises, it cools adiabatically due to decreasing atmospheric pressure. When the rising air reaches its dew point temperature (the temperature at which air becomes saturated with moisture), condensation occurs, leading to cloud formation. At altitudes above approximately 2000 meters (around 6560 feet), the cooling of air during ascent can often cause it to reach saturation and form clouds assuming sufficient moisture content in the air mass. Keep in mind that actual cloud formation altitudes can vary based on local atmospheric conditions and the initial characteristics of the air parcel.
