Answer: cold and warm air masses interact in an unstable environment.
Explanation: Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild showers to heavy gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale (synoptic) low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone .According to the polar-front theory, extratropical cyclones develop when a wave forms on a frontal surface separating a warm air mass from a cold air mass. As the amplitude of the wave increases, the pressure at the centre of disturbance falls, eventually intensifying to the point at which a cyclonic circulation begins. The decay of such a system results when the cold air from the north in the Northern Hemisphere, or from the south in the Southern Hemisphere, on the western side of such a cyclone sweeps under all of the warm tropical air of the system so that the entire cyclone is composed of the cold air mass. This action is known as occlusion.Extratropical cyclones arise through a process called cyclogenesis, in which cold and warm air masses interact in an unstable environment.

Answer:
Explanation:
Step 1:
the auditor is required to provide reasonable assurance for the financial statement audited.To provide such reasonable assurance,appropriate evidence must be obtained to confirm that no material misstatement material is present in the financial statement
Step 2:
For each statement select true or false in the following manner
a. A recent improvement in computer hardware is the ability to automatically produce error listings. Previously, this was possible only when provisions for such a report were included in the program.
FALSE
b. The control of input and output to and from the information systems department should be performed by an independent data control group.
TRUE
c. An internal-audit computer program that continuously monitors IT processing is a feasible approach for improving internal control in OLRT systems.
TRUE
d. An internal label is one of the controls built into magnetic tape drive hardware by the hardware manufacturers.
FALSE
e. A limit test in a computer program is comparable to a decision that an individual makes in a manual system to judge a transaction's reasonableness.
TRUE
f. A principal advantage of using magnetic tape files is that data need not be recorded sequentially.
FALSE
g. A major advantage of disk files is the ability to gain random access to data on the disk.
TRUE
h. The term grandfather-father-son refers to a method of protecting computer records rather than to generations in the evolution of computer hardware.
TRUE
i. When they are not in use, tape and disk files should be stored apart from the computer room under the control of a librarian.
TRUE
As a product moves into the market maturity stage of its life cycle, the marketing manager should expect the market to move toward pure competition.
Maturity is the time when sales start to plateau from the boom. At this point, companies start cutting prices to remain competitive in the face of increased competition.
Maturation occurs after introduction and growth. Maturity is the longest stage in the product life cycle. At this stage, sales growth starts to decline. The company reaches a high point in the demand cycle. and promotional strategies have minimal impact on revenue growth. December 20, 2021
