Into the Jungle Chapters 5&6

What characteristics made Roy Chapman Andrews particularly adept at exploration?

Roy had a lot of experience outside with nature and with his father along side with him. Andrews loved to fish, hunt and even camp out.

Why were experts in different disciplines vital to the expedition and its success?

The reason why they were needed is because each held a specific job or end.

They each focused on something major or what they are so called "masters"

in. With the knowledge of each of these people they could easily survey the land with better outcomes rather than one person doing all the work

What was the significance of the discovery of dinosaur eggs?

The discovery of the dinosaur egg led them to future things that had happen

like they had no idea that dinosaur's themselves could lay eggs. These fossils

led to a new discovery of a dinosaur.

Why did the American Museum of Natural History scientists consider the mammal fossil so important?

It was proof to the Age of Dinosaurs era had existed and that the dinosaur fossils led the discovery of many new breed of species.

The extinction of the dinosaurs, ammonites, and other creatures at the end of

the Cretaceous was well known for many decades prior to the Alvarezes'

discovery. Why did Walter Alvarez, a geologist, and Luis Alvarez, a nuclear physicist, crack a mystery that paleontologists and biologists had not?

Both of the alvarez found traces of iridium at places and he was purposing how exactly the extinction came about when Chris Mckee a astronomer colleague told him that an asteroid could have hit the earth. Alvarez started to think about this and decided that this asteroid had to be massive and had to have a great impact on the land.

What were the pieces of evidence that led to the identification of Chicxulub as the asteroid impact site?

Alan Hildebrand discovered certain "gravity anomalies." He found that

tektites form under high temperature, which could be a cause of the asteroid itself crashing into earth. He found that these tektites were also found mainly in Haiti and later labeled out that the asteroid should have been near that

area. That's when later someone had contacted them that the asteroid was

near the Yucatan peninsula.

What might be the local and global effects of future smaller or similar-sized asteroid impacts?

The local and global effects of this asteroid impacting earth could cause a mass extinction depending on how large and fast the asteroid is traveling towards earth. Thus indicating that during the future we cannot assume that no more asteroids would hit the earth but there will be many more to come.
