The dust blocked sunlight so plants died. Then the dinosaurs that ate plants died. Last, the meat-eating dinosaurs died. Few have survived like the shark for instance.-Its called evolution.......
It has also been suggested that disease killed off the dinosaurs. A very deadly and contagious disease may have circulated among the dinosaurs forcing them to become extinct. Still yet another theory is that the Earth just gradually changed in climate over a long time period and the dinosaurs were not able to adapt to the cooler, dryer climate.
There was a meteor that hit earth and it caused a dust cloud to surround the earth and the dinosaurs died from lack of light for that period of time. Birds are modern dinosaurs and they survived because they could fly over the dust cloud. Many animals become extinct because of humans. Oil spills kill many animals today.
The earth took a meteor to the face. The explosion was so huge that it covered the earth in dust. The dust blocked sunlight so plants died. Then the dinosaurs that ate plants died. Last, the meat-eating dinosaurs died. Few have survived like the shark for instance.
It's called evolution. Conditions on the Earth changed and some animals were able to adapt while others were not able to. When the Earth became cooler the large cold blooded dinosaurs died while the smaller warm blooded mammals took over.
evolution-dinosaurs couldnt adapt well, or quick enough to their rapidly changing environment to survive
Evolution.
