How Did Dinosaurs Die?

Answer

There are many theories as to how the dinosaurs became extinct. There is however no absolutely proven theory. The most popular theory is the Asteroid Theory. According to this theory a large asteroid collided with Earth about 65 million years ago. It is believed such a large collision would throw so much dust into the air that sunlight would not be able to shine and plants and animals would die. The dramatic changes in climate that resulted from this huge collision were too much for the dinosaurs. They were not able to survive.
