<h3>Answer;</h3>
<em><u>Sand Spit or Spit </u></em>
<h3><u>Explanation;</u></h3>
- <em><u>Long shore drift is the process that occurs when a sheet of water moves on and off the beach, in other words the swash and back swash</u></em>, thus capturing and transporting sediment on the beach back out to the sea.

<h2>Answer:</h2>
The part of the electromagnetic spectrum usually used for communication is of radio waves, infrared waves and microwaves.
But most common waves used in communication are radio waves.
<h3>Explanation:</h3>
- Radio waves are used to transmit television and radio programmes.
- While microwaves are used for mobile phones and Wi-Fi.
- Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.
- Radio waves have frequencies as high as 300 gigahertz (GHz) to as low as 30 hertz (Hz).
