The distance from point a to point b is known as the a) amplitude. b) frequency. c) pitch. d) wavelength.

The answer is A) Amplitude

Explanation: Point A to B represents the amplitude. As amplitude, or wave height, of a sound wave changes, the volume of the sound changes.

(Next time put a image of the Diagram so people can understand your question)!!!

c

explanation:

i think

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
