Answer: As altitude increases, atmospheric pressure decreases
Explanation:
Atmospheric pressure 
is defined as the force 
per unit area 
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.
C. Clay soil has a higher porosity than sandy soil.
Explanation:
Maller soil particles have smaller pore spaces, but a greater number of them, which leads to higher surface tension and high % porosity.
