Question 3

Is the risk of disaster from Asteroid Impacts, high or low? Choose the best answer.

Accepted Answer

A)  Relatively high because although large asteroid impacts are rare, they can cause catastrophic effects such as mass extinction 
B)  Low because asteroid impacts only cause damage in a very local region 
C)  High because large asteroid impacts are fairly common 
D)  Low because because there are only two documented large asteroid impacts in the Earth's entire geologic history 
E)  No one really knows because Asteroid impacts are completely unpredictable.

Question 4

Many meteorites have been found in Antarctica.

Accepted Answer

A) True 
 B)False

Question 5

How are scientists preparing for a possible asteroid impact?

Accepted Answer

A)  They are fortifying areas most likely to be hit. 
B)  They are devising shielding devices that will be stationed on the Earth to reflect impacts. 
C)  They are cataloging objects in the sky that might be dangerous. 
D)  They are working on supercooling devices to decrease the incidence of wildfires caused by an impact. 
E)  They aren't doing anything. Asteroid impacts are not likely enough for scientists to be concerned.

A large asteroid impact would produce a

Question 8

What triggered the formation of the Sun?

Accepted Answer

A)  Supernova explosion 
B)  Big Bang explosion

D)  Electromagnetic attractions 
E)  No one knows.

Question 9

If there was an asteroid of the same size as the one at the K-Pg Boundary, would it mean a Mass Extinction that includes humans? Choose the best answer.

Accepted Answer

A)  Yes. Humans could not survive the heat and shock waves of an asteroid impact. 
B)  Yes, if the impact was in the ocean. Humans could not survive the tsunami. 
C)  No. Humans have too much technology to be hurt. 
D)  No. Asteroids aren't strong enough to cause a mass extinction. 
E)  Probably, humans are at the top of the food chain, which makes them vulnerable.
