Select the BEST response below to describe how moist air can be lifted to form a cloud (select one response below): Group of answer choices Orographic lifting occurs when air is forced upward by a barrier of mountains or hills. Convective lifting occurs when air heated at the earth's surface rises in the form of thermal currents or bubbles. Widespread ascent results from the interaction of air masses, or the movement of a cold air mass forcing warm air to rise ahead of it. Mechanical (or frictional) turbulence occurs when the air flow is deformed into a series of eddies as it moves over the earth's surface. All of the above.
