Listen, look and read. Why did the dinosaurs die?

The dinosaurs lived on Earth for more than 100 million years. Then, 65 million years ago, all dinosaurs became extinct. What happened?
1. Some scientists think a giant meteor hit the Earth. It made a giant hole in the rock under the sea.
2. Liquid rock erupted from the hole and the sea rushed in. The water turned into steam.
3. A thick cloud of steam and dust covered the whole sky. All over the Earth, the weather became very cold.
4. It was too cold for the dinosaurs. They did not have any fur to keep them warm. Many dinosaurs died.
5. The dinosaurs lived in rain forests. The cold weather killed the plants in the forests. So the plant-eating dinosaurs died.
6. When the plant-eating dinosaurs died, the meat-eating dinosaurs had no food. They died, too.
