TEST- Atmosphere and Weather- Do Not Write on the TEST
Modified True/False
Indicate whether the statement is true or false. Mark A for true and B for False.
____ 1. A combination of many ​liquids​ makes up Earth’s atmosphere.
____ 2. The source of rain, clouds, and snow is ​ozone​.
____ 3. The sun shines on and warms Earth’s surface directly in a method of energy transfer
known as ​radiation​.
____ 4. For Earth to remain habitable (livable) the amount of energy received by the sun and the
amount of energy returned to space is approximately (~) equal. This is called ​radiation
balance​.
____ 5. The atmosphere is composed mostly of ​helium​ and oxygen, with traces of other gases
such as carbon dioxide and water vapor.
____ 6. The stratosphere is important because it contains ​nitrogen​, which blocks harmful
ultraviolet radiation from the Sun.
____ 7. Both temperature and pressure generally ​decrease​ with height in the troposphere.
____ 8. Due to the ​Coriolis Effect,​ moving air particles are deflected to the right in the
northern hemisphere and to the left in the southern hemisphere.
____ 9. Strato​ clouds are found in the lower atmosphere.
____10. Dust and sea salt are particles (particulate matter) in the atmosphere that must be
present to form clouds. These are called ​convection nuclei​.
