What does the constant speed of sound waves help calculate?

• Exact depths

• Water temperature

• Fish population

• Ocean currents

What is the significance of the echo signals detected by sonar devices?

• They provide information on ocean depth

• They indicate water temperature

• They show fish locations

• They measure wave height

What is the main challenge in mapping the ocean floor?

• The ocean floor is not visible from the surface

• The ocean is too deep

• There are too many fish

• The water is too cold

Sonar devices send out sound wave "pings" and detect returning echoes.

• Sonar devices use light waves to detect objects.

• Sonar devices use radio waves to communicate.

• Sonar devices use sound waves to detect objects.

• Sonar devices use infrared waves for detection.
