Question 34

How does the asteroid impact hypothesis explain extinction of dinosaurs and other species?

Answer 34

Dinosaurs died from shock, broiled to death, smoke in lungs, lack of sunlight stopping photosynthesis which caused the whole food chain to fall

Question 35

Everyone believes this theory to be true? True or False?

Answer 35

False

Question 36

Everyone was slow go accept the asteroid impact theory...why?

Answer 36

The man who came up with it was a physicist to they doubted his ability and knowledge

Question 37

Why did smaller animals survive asteroid impact?

Answer 37

Smaller amount of food needed, shorter gestation period, lived in the ground so some protection, and reproduce in larger numbers
