Dinosaurs
Several theories have been proposed about why the dinosaurs disappeared from the face of the Earth. In recent years one popular theory proposes that climatic changes caused the dinosaurs to become extinct. This climatic change theory says that millions of years ago climate of the world gradually became colder. As the earth slowly became colder fewer plants were able to grow. The cold weather finally resulted in a severe shortage of food for the dinosaurs. As you probably know most of the dinosaurs were vegetarians and they depended on plants for their food supply. In summary then the disappearance of the dinosaurs was caused directly by shortage of plants to eat and indirectly by a change in the climate.
Now many scientists still believe that the climatic change theory best explains why the dinosaurs disappeared. This theory argues that the dinosaurs disappear gradually, slowly, as the Earth became colder and their food supply dwindled.
Today there is new evidence to the theory that the dinosaurs did not disappear gradually, but that they disappeared quickly and suddenly. This theory is known as the asteroid theory. It states that the huge asteroid or perhaps a comet hit the Earth about 65 million years ago. When this comet or asteroid hit the Earth, it caused a huge dust cloud. The huge dust cloud covered the whole Earth and blocked out the sun for month. Since there was no sun foe many months, most of the plants on earth died. The dinosaur’s food supply was destroyed in the period of month. Well, this asteroid theory is not new. What is new is the evidence for the theory. Until recently there was no evidence that the asteroid or a comet hit the Earth 65 million years ago. What happened recently was that scientists found large amounts of rare earth element called Iridium all over the world. This iridium was found in the layers of the earth that is 65 million years old. The iridium was found in the same layers where the bones of the last dinosaurs were found. The element iridium is very uncommon and in fact rare on the earth. It is an element however, that is more often found in space. Scientists speculate that this iridium was brought to the earth 65 million years ago when a comet or asteroid hit the earth. Comet or asteroid theory explains 2 things. Number 1: it explains the large amount of the iridium found in 65 year-old-layers of earth. And number 2: it explains why the dinosaurs disappear from the earth.
Now today scientists continue to debate the two theories: the climatic change theory and the asteroid theory. In the future evidence may be found that supports a totally new theory of why the terrible lizards died out.
