The reason for the extinction of the dinosaurs, who knows the reason for the extinction of the dinos

So far, the cause of the extinction of the dinosaurs has been thought to be caused by the impact of an asteroid on the earth, but recently scientists have used geology and paleontology to come to a new conclusion, that is, the extinction of the dinosaurs was due to the eruption of the earth's volcanoes, and this theory has been confirmed by a series.

American scholars led by Helda Keller have speculated that the extinction of the dinosaurs was due to the eruption of volcanoes at the bottom of the Indian Ocean through the analysis of mineral particles in sediment layers deep in the ocean floor.

Studies have shown that during periods of intense activity at the Earth's core and great changes on the surface, large amounts of magma erupted in columnarity, so that hot material from the mantle spread and flowed on the surface, and it is estimated that the magma covered an area with a radius of about 500 kilometers. Such an explosion lasted for a million or two million years, and formed millions of cubic kilometers of lava, and the dinosaurs inevitably perished. References:

There are three conjectures about the extinction of dinosaurs, namely: climatic causes, planetary impacts on the earth, and volcanic eruptions. Scientists have calculated the last extinction of dinosaurs based on the age of the rock where the dinosaur fossils are located 65 million years ago, and no one knows the answer to the specific cause of the extinction of the dinosaurs, so they can only speculate.

Why are the dinosaurs so clean to extinction?

Climatic causes: There was a huge change in the Earth's surface that changed the Earth's climate so much that the dinosaurs became extinct due to lack of food.

Planets hit the Earth: Some scientists believe that 65 million years ago, a huge asteroid hit the Earth, and a large amount of soot entered the air, causing plants to stop growing, and the subsequent outbreak of air pollution, food shortages, disease, etc., led to the extinction of the dinosaurs.

Volcanic eruption: Volcanic eruption produces a large number of toxic gases and harmful substances, and also causes secondary disasters such as ** and tsunamis, which can not only directly kill dinosaurs, but also cause long-term pollution to the surrounding environment, affect the reproductive function of dinosaurs, and cause dinosaurs to hatch significantly and become extinct.
