Sound does not travel in space because

• Space is too far away.
• There is no matter in space.
• Space is the final frontier
• Space has planets.

Sound is a form of _________________ that travels as waves through a ________________.

• light/ transparency
• energy/ vibration
• energy/ medium
• frequency/ medium

Why is sound able to travel faster through a solid than a gas?

• Gas molecules are packed tightly.
• Sound does not travel faster through a solid than a gas.
• Solid molecules are packed tightly.
• Gas molecules move slowly.

Which materials reflect sound well?

• 
• 
• 
• 

The diagram shows a research vessel using sonar to map the ocean floor.

Upon which basic behavior of sound waves does this technology depend?

• absorption

• compression

• reflection

• refraction

This is what you get when sound waves are reflected, or bounce back, off of a hard surface.

• Amplitude
• Pitch
• Volume
• Echo

What is a pitch?

• highness or lowness of a sound
• the intensity of a vibration
• the amplitude of the sound wave
• volume of sound

Material (matter) through which a wave travels

• medium
• Doppler Effect
• sound
• pitch

A disturbance that carries energy such as sound or light

• sound wave
• electrical energy
• amplitude
• volume

the layer on which living beings live is ...

• crust
