Nothing really tells us what did kill the dinosaurs , It remains a mystery. There are many theorys that might have caused the dinosaurs extinction. An asteroid could crash into the lithosphere which is the earths crust. It can cause earth quakes and volcanic eruptions. It can even effect the hydrosphere which is the solid, lliquid, and gaseuous forms of water on earth. It could cause floods and drought which means the dinosaurs either drown or can't get any water. This is a big one. If an asteroid came down and hit the earth it can easly affect the biosphere. All plant and animal life is in the biosphere. If an asteroid hits any of that it can cause food shortages and even forest fires. Pretty soon there will be no food or shelter for the dinosaurs to eat or live in and there comes along extinction. The asteroid can affect the earths atmosphere too. From all the dust and debree coming off the asteroid, it can make the air polluted and hard to breathe. Some dinosaurs could stop breathing and die. It could even be hard to see too! The spheres that could have been involved are the:
-Lithosphere
-Biosphere
-Hydrosphere
-Atmosphere
There is another theory of the dinosaurs becoming extinct. A volcano could have erupted causing fires, drought, and even kill some of the dinosaurs. There many more examples of what could of happened.
