Chemical composition is always a property of an ore.
It was a life changing event. Around 66 million years ago, at the end of the Cretaceous period, an asteroid struck Earth, triggering a mass extinction that wiped out the dinosaurs and around 75% of all species.
Dinosaurs roamed the Earth in the Mesozoic Era, which is divided into the Triassic, Jurassic, and Cretaceous periods. They first arose during the Triassic period about 245 million years ago. Dinosaurs first appeared in the Middle Triassic and became the dominant terrestrial vertebrate in the Late Triassic or Early Jurassic, occupying this position for about 150 to 135 million years until their demise at the end of the Cretaceous. This era is popularly known as the "Age of Reptiles" and for good reason: reptiles, and particularly dinosaurs, were the dominant terrestrial vertebrate animals at the time. The PT extinction was the most severe in Earth's history, and was likely driven by intense volcanic eruptions and associated rapid climate change. This extinction decimated many early groups of reptiles and amphibians, and may have created environmental space for dinosaurs and other new groups to evolve.

Answer:
Iceland, and states like Washington DC.
, South Dakota, Connecticut, Idaho, New Hampshire, Delaware, North Dakota, Illinois.
Explanation:
Iceland is one of the only places where people live without insects.
The reason why Iceland does not have mosquitos or other insects is its oceanic climate that keeps them away.
The insects freeze 3 times a year, which makes their survival in Iceland impossible.
The other states are not completely insect-free, however, their number is so small that is considered as like they don't exist.
