"The Extinction of the Dinosaurs" PPT Courseware 2

I can read

Humanity avoids withering for a while

death, eating, hatching, books, dust

Or mammals can't stand the mystery

Reading requirements:

Think about the theories about the extinction of dinosaurs introduced in the text.

One theory is that there was a time when the earth suddenly became very cold. Dinosaurs did not have the habit of hibernating. They could not use hibernation to avoid the cold like snakes and turtles. In addition, dinosaurs had no fur to keep them warm, so they could not withstand the severe cold and slowly disappeared.

Another theory is that a cosmic planet collided with the earth, and the dust covered the sun, leaving the earth in darkness. Because there was no sunlight, a large number of plants withered and died. Dinosaurs and other animals that fed on plants gradually died. As the number of animals decreased, the carnivorous dinosaurs could not find enough food and gradually became extinct.

Will you fill in the serial number?

( ) Dust obscures the sun.

( )The planet hit the earth.

( ) The carnivorous dinosaurs became extinct.

( ) Herbivorous dinosaurs and other animals died.

( ) Plants withered and died in large numbers.
