Question 2      
Identify the false statement. There is very little rock record for Earth's first 600 million years because:
Correct Answer:
the surface then was one huge ocean basin filled with hot water and nothing else.

Archean

Which of the following has nothing to do with fossils?
Correct Answer:
Rodinia
       
Question 5      
Which of the following statements is false? The first life forms:
Correct Answer:
probably occurred in oxygen-rich, shallow, warm ocean waters.
       
Question 6

This common, cheap, and useful form of limestone consists of microscopic marine algae shells and shrimp feces. Thick Cretaceous-age deposits of it are common in Europe.
Correct Answer:
chalk
       
Question 11      
Identify the false statement. Internal differentiation:
Correct Answer:
"stirred" Earth's interior and thus hastened Earth's cooling.
       
Question 12      
Which of the following was NOT a component of Earth's Hadean atmosphere?
Correct Answer:
oxygen
       
Question 13      
Identify the false statement.
Correct Answer:
80% of Earth's continental crust existed by the end of the Hadean  eon.
       
Question 14      
Identify the false statement. During the Pleistocene ice age:
Correct Answer:
continental glaciers covered all of North America.
       
Question 15      
Identify the false statement.
Correct Answer:
Atmospheric oxygen and nitrogen react to form the nitrogen oxide that protects land life from harmful ultraviolet rays.
       
Question 16

Correct Answer:
all of the above are true statements.
       
Question 17      
Rodinia, Pannotia, Grenville, and Pangaea are all names of supercontinents.
Correct Answer: False
       
Question 18      
Banded-iron formations (BIFs) are forming today along mid-ocean ridges.
Correct Answer: False
       
Question 19      
Gymnosperms (naked-seed plants like conifers) were widespread in the late Paleozoic; angiosperms (flowering plants) gained dominance in the late Mesozoic.
Correct Answer: True
       
Question 20      
Theoretically "snowball Earth" of the late Proterozoic eon would have stayed ice-covered forever were it not for greenhouse warming caused by carbon monoxide from volcanoes.
Correct Answer: False
       
Question 21      
It wasn't until the late Mesozoic that vascular plants with woody tissues, seeds, and veins shared the land with spiders, scorpions, insects, and crustaceans, while jawed fish cruised the oceans and the first amphibians left water to visit land.
Correct Answer: False
       
Question 22      
The Paleozoic era, like the Mesozoic era, may have ended with mass extinction of life forms due to a huge meteor impact.
Correct Answer: True
       
Question 23      
The continents that comprised Pangaea came together in the early Paleozoic, but began to split apart soon afterward, during the late Paleozoic.
Correct Answer: False
       
Question 24      
During the Hadean the Earth kept getting hotter due to meteorite impact and compression; radioactive elements didn’t yet exist to contribute heat energy.
Correct Answer: False
