Reasonable suspicion is defined by a set of factual circumstances that would lead a reasonable police officer to believe criminal activity is occurring. This is different from the probable cause (what a reasonable person would believe) required for an arrest, search, and seizure.
PunaluÊ»u Beach (also called Black Sand Beach) is a beach between PÄhala and NÄÊ»Älehu on the Big Island of the U.S. state of Hawaii. The beach has black sand made of basalt and created by lava flowing into the ocean which explodes as it reaches the ocean and cools.
While some beaches are predominantly made of black sand, even other colour beaches (e.g. gold and white) can often have deposits of black sand, particularly after storms. Larger waves can sort out sand grains leaving deposits of heavy minerals visible on the surface of erosion scarps.
