<span>The Inner Planets dense and rocky because they are close enough to the sun that the heat has driven off the free hydrogen and helium which forms most of the Gas Giant planets (and most of the universe). Only the heavier elements remain.
And please put the questions in right subject. It belongs to "Physics" not for "Biology".
Hope this helps!</span>
The correct answer is choice D
Amplitude
Energy
Explanation:
The amplitude is the height of the wave and measures the amount of energy it carries.
Amplitude of a wave is the maximum amount of displacement of wave from rest.
The energy of the a wave is the amount of disturbance a wave transmits.
- The amplitude of a wave is the wave height.
- It measures the vertical height through which a wave passes through.
- Waves that have a high vertical displacement i.e high amplitude carries a lot of energy.
E = kA²
where E is wave energy , k is the wave number and A is the amplitude of the wave.

I'm not sure if this is a multiple choice question. But, my answer would probably have to be, feces. When an animal passes foods, it adds nutrients to the earth, and when plants die they also go into the earth to help fortify and regurgitate it. Hope this helps. :D
