Wave B.
All sound waves move at nearly the same speed through the air.
High-frequency sound waves have a shorter [amplitude] [pitch] [wavelength] and a higher [amplitude] [pitch] [wavelength] than low-frequency sound waves.

Disturbances inside Earth’s core cause earthquakes. The starting point of the disturbance is called the epicenter. Why does the amplitude of a seismic wave usually decrease as the wave moves away from the epicenter?
You are a sales representative for a company that makes a new alternate fuel for vehicles. You have prepared a presentation for the environmental engineers to sell your new product. What question do you expect the audience to ask regarding whether the new fuel will cause less damage to the environment?

The citizens of a town are aware of climate change, and they want to make changes to control it. One change they consider is replacing the nearby thermal power plant with a hydroelectric plant. If they want to make sure this change will help to slow climate change, which question should they ask?
Does a hydroelectric power plant emit less CO2 than a thermal power plant?
A.
the height of a wave from its equilibrium position is called
amplitude
Which statement explains why greenhouse gases are needed for the survival of life on Earth?
B. Without greenhouse gases, Earth would be too cold for life to exist.
