History & Early Earth Quiz

Earth appears to have fewer impact craters when compared to the surface of similar structures within our Solar System (other planets and moons).  Which geological processes have contributed to this difference? Mark all that apply.

• earthquakes

• global warming

• volcanic activity

• tornadoes

• weathering

One reason why not as many craters are found on Earth as on the other space bodies is because...

• it was much hotter on Earth than other space bodies.

• there was oxygen in Ancient Earth’s atmosphere.

• the Earth’s surface is covered with water.

• very few asteroids or comets hit the Earth.

Approximately how old is the meteorite if 23% of the original Uranium-238 that remains?   

• 8,800 million years old

• 9,000 billion years old

• 9,200 million years old

• 11,000 million years old

How many half-lives have passed if a meteorite has 12.5% Uranium-238 remaining?

• 1 half life

• 2 half lives

• 3 half lives

• 4 half lives

No exact radiometric dating is possible due to the process of plate tectonics because...

• rocks have been recycled and destroyed.

• not all radioactive elements have known half lives.

• there is no evidence of tectonic plate movement.

• because no life existed on Ancient Earth.

The conditions of Ancient Earth during the Early Heavy Bombardment included...

• oxidized iron

• oxygen-rich oceans

• radioactive materials

• continents formed from asteroid impacts.

The steady low production of oxygen in the Earth’s atmosphere was due to

• the presence of tropical forests

• predation 

• the lack of carbon dioxide in atmosphere

• activity of cyanobacteria like stromatolites

The dip in oxygen levels in the Earth’s atmosphere around 250 mya may have been caused by

• an increase in photosynthetic rate.

• iron oxidation.

• increased oxygen consumption by larger and more active animals.

• burial of organic matter due to plate tectonic activities.

Which of the following statements is NOT CORRECT? The bright red bands found in newer rocks...

• were caused by  iron reacting with oxygen and water.

• relate to oxygen present in the atmosphere.

• are not present in ancient rocks.

• appear as a result of radioactive decay.
