As a result of the hot spot volcanoes of Iceland and Hawaii producing a huge amount of basalt, the nearby beaches are made of <u>black sand.</u>

<h3>What is the effect of Basalt on sand?</h3>
Basalt is a black volcanic rock that is commonly found around volcanoes. It has this coloration and appearance as a result of a high concentration of augite and other dark minerals.
Areas with a high concentration of basalts, such as beaches in Iceland and Hawaii, will reflect this dark hue coloration by generating black sand when combined with basalt.
