The asteroid theory of dinosaur extinction proposes that a massive asteroid impact on Earth about 65 million years ago was responsible for wiping out the dinosaurs. To write a paragraph about this theory, you can start by mentioning the geological evidence that supports it. One of the most significant pieces of evidence comes from the discovery of a layer of sediment dating back to the end of the Cretaceous period, known as the K-Pg boundary. This layer contains a unique combination of elements, including high levels of iridium, which is rare on Earth but more abundant in asteroids. Additionally, researchers have found shock quartz and microtektites, tiny glass spheres formed by the intense heat and pressure of an impact event. These geological findings align with the hypothesis that a massive asteroid struck the Earth, causing widespread devastation and ultimately leading to the extinction of the dinosaurs.
