In this circumstance one should revise the hypothesis and develop a new experiment to test it.An example could be the theory of Agraham Gottloeb Werner that all rocks were precipitated from water including not just sedimentary rocks but also volcanic, plutonic and metamorphic rocks. The more the earth was studied, especially by James Hutton in Scotland, the more it became obvious that granites for example were deposited in a molten state, thus disproving that hypothesis or theory. 
        
             
        
        
        
Answer:
C. A mass of air that is similar in temperature and humidity
Explanation:
An "air mass" refers to a big volume of air that is characterized by having similar or uniform "temperature" and "humidity"<em> (moisture).</em> They come from different source regions, thus they are classified accordingly. 
The<em> "cold air masses"</em> come from the <u>polar area</u>s while the<em> "warm air masses"</em> come from the<u> tropical areas.</u> An air mass may cause a storm, for example, when an air mass moves to a new region and confronts another air mass there with a<em> different humidity and temperature</em>.

Answer: As altitude increases, atmospheric pressure decreases 
Explanation:
Atmospheric pressure  is defined as the force
 is defined as the force  per unit area
 per unit area  the air that forms the atmosphere exerts on the Earth's surface:
 the air that forms the atmosphere exerts on the Earth's surface:

It should be noted that as the altitude increases less air is above and, therefore the air weights less. This is because the atmosphere losses density as we ascend, causing less air.
However, it is important to point out this decrease in pressure is not linear, since at the beginning (in the first kilometers above sea level) it reduces more rapidly than in the next kilometers above. That is why this relationship between atmospheric pressure and altitude is exponential.
