Emma draws another diagram showing how adding energy affects this wave. How does her new diagram compare to this diagram? A
Her diagram shows higher wavelengths.
B
Her diagram shows lower wave amplitudes.
С
Her diagram shows lower wave frequencies.
D
Her diagram shows higher wave amplitudes.

I would say it’s either B or D

Explanation:

I don’t know if it’s asking about her current diagram

the answer is learned

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
