Question 1 1 / 1 pts A conditionally unstable atmosphere is stable with respect to unsaturated air and unstable with respect to saturated air. Correct! True False Question 2 1 / 1 pts The elevation where clouds form is called the ____ level. Correct! condensation saturation precipitation nominal cloud atlas Question 3 1 / 1 pts Inversions that form as air slowly sinks over a large area are called ____ inversions. They sometimes occur at the surface, but more frequently, they are observed aloft and are often associated with large high-pressure areas because of the sinking air motions associated with these systems. occlusion opaque depression buoyancy Correct! subsidence Question 4 0 / 1 pts Sinking air sometimes cools adiabatically. You Answered True Correct Answer False Question 5 1 / 1 pts Conditional instability depends on the condition of ____. wind low pressure subsidence ionization Correct! saturation Question 6 1 / 1 pts If an air parcel is given a small push upwards and it continues to move upwards on its own accord, the atmosphere is said to be ____. stable acidic Correct! unstable buoyant alkaline

Question 7 1 / 1 pts A rising parcel of air that does not exchange heat with its surroundings is an example of ____. forced lifting isothermal ascent advection Correct! an adiabatic process convection Question 8 0 / 1 pts In a conditionally unstable atmosphere, the environmental lapse rate will be greater than the moist adiabatic rate and ____ the dry adiabatic rate. Correct Answer less than consistent with You Answered greater than the same as inconsistent with Question 9 1 / 1 pts The rate at which the actual air temperature changes with increasing height above the surface is referred to as the ____ rate. Correct! environmental lapse dry adiabatic absolute stability moist adiabatic thermoclinic Question 10 1 / 1 pts When the ____ is between the moist adiabatic rate and the dry adiabatic rate, it creates a situation known as a conditionally unstable atmosphere. Correct! environmental lapse rate pressure difference subsidence inversion wind velocity plus pressure neutral zone Question 11 1 / 1 pts Altocumulus clouds that show vertical development and produce tower-like extensions are called ____. cumulus turris Correct! altocumulus castellanus cirrocumulus castellanus cumuloturrim cumulonimbus Question 12 0 / 1 pts

The temperature of rising air at a given level inside a cumulus cloud is normally warmer than the air around the cloud. Correct Answer True You Answered False Question 13 1 / 1 pts ____ appearing in the sky indicates that the mid-level of the troposphere is becoming more unstable. Cirrostratus clouds The color blue Stratus Nimbostratus clouds Correct! Altocumulus castellanus Question 14 1 / 1 pts ____ is a condition in which the environmental lapse rate is equal to the dry adiabatic rate. Correct! Neutral stability Conditional instability Coriolis compensation Charged instability Subsidence inversion Question 15 1 / 1 pts The environmental lapse rate is almost always the same as the adiabatic rate. True Correct! False Question 1 1 / 1 pts What transfers heat upwards into the atmosphere? Billows Correct! Thermals Solar inversions Subsidence inversions Cloud sheet Question 2 1 / 1 pts The dry adiabatic rate is the rate at which ____. an air parcel rises latent heat energy is released in a rising air parcel pressure changes in a rising or descending parcel of saturated air Correct! temperature changes in a rising or descending parcel of unsaturated air volume changes when a parcel expands or is compressed Question 3 1 / 1 pts Which of the following is not a mechanism primarily responsible for most clouds
