Earth is protected by a blanket of air called the (1). Earth’s atmosphere is made of many gases. The two most abundant
gases in dry air are (2) and (3). Carbon dioxide and (4) help prevent heat loss from Earth. (5) is a form of oxygen located
high in Earth’s atmosphere that absorbs ultraviolet radiation. Atmospheric pressure is (6) at sea level and (7) outward from
Earth’s surface. Molecules of (8) air are farther apart than those of cool air. Thus, warm air is (9) dense than cool air. The
(10) is an apparent force that results from Earth’s eastward rotation. It affects air circulation by turning air masses (11) from
their original path if they are viewed from the equator. Strong belts of wind in the tropopause that flow from west to east and
are useful to pilots are called (12).

Conditions of the atmosphere relating to air pressure, wind, temperature, and moisture are referred to as (13). (14) are
scientists who study weather. (15) is the average of all weather conditions of an area over an extended period of time. An
area which receives less than 25 cm of annual rainfall is called a (16). (17) is a measure of the actual amount of moisture in
the air at a particular time, while (18) is the comparison of the amount of water currently in the air to the amount of total water
possible for the air to hold. Water escapes from the earth into the atmosphere as vapor by (19). Once the air becomes
saturated and dust or salt particles are present, condensation occurs to form (20) made of tiny droplets of water. When the
droplets of water become large enough, they may fall as (21) or other forms of (22). Clouds are classified into three basic
types based on their shapes: (23), (24), and (25). Stratus clouds that form close to the ground are known as (26). Clouds
that give rain often have the suffix (27) attached.

Weather instruments include (28), (29), and (30). Lines connecting points of equal pressure are called (31). Lines
connecting points of equal temperature are called (32). A body of air that has the same properties as the area over which it
develops is called a (33). If it is a warm air mass, it is called (34). A cold air mass is called (35). A dry air mass is referred
to as (36), a wet air mass is called (37). Two air masses that meet do not mix but form a boundary called a (38). A (39)
occurs when a warm air mass meets a cold air mass. A (40) occurs when a cold air mass invades a warm air mass. When
neither air mass can push the other out of the way, a (41) forms. When warm, moist air masses are forced rapidly upward
into cooler, drier areas, (42) often develop. When a current flows from one electrically charged area in a cloud to another of
opposite charge, (43) occurs. The loud sound caused by the accompanying pressure wave is called (44). Lightning will
strike the (45) object in the area. A violent whirling wind associated with thunderstorms along cold fronts is known as a (46).
During winter months, (47) may occur in which 50 to 75 kilometer per hour winds, below zero temperatures, and blowing
powdery snow create very dangerous conditions. Tropical cyclones or (48) are nearly circular storms with winds over 120
km per hour. A (49) is issued when severe weather conditions could occur and a (50) is issued when severe conditions exist
in an area.
