This statement is false. There is actually five types of plains. The five types of plains are coastal plain, alluvial plain, glacial plain, terrestrial plain and flood plain. Plains are flat areas that are usually located in lowlands and at the bottom of the valleys.
Sound waves are mechanical waves, longitudinal waves, and do no transmit in a vacuum
Explanation:
Sound waves are periodic disturbance of a medium that generates that are produced when a rapid vibration of an object produces a similar periodic vibration in the particles of a medium. Therefore, sound waves are the periodic vibrations of the particles in the medium.
Sound waves are classified as longitudinal waves. Longitudinal waves are those in which the particles of the medium vibrate in a direction parallel to the direction of propagation of the wave: therefore, the particles vibrate back and forth along the direction of motion of the wave.
Sound waves are able to travel through different mediums: gases, liquids and solids. In particular, they travel faster in solids than liquids, and in liquids than gases, because the particles in solids and liquids are closer together, so the transmission of the wave is more efficient.
Sound waves are also classified as mechanical waves, which are waves that transmit through the vibrations of the particles in a medium. For this reason, sound waves cannot propagate if there is no medium: therefore, sound waves cannot propagate in a vacuum.
