Science Quiz 8.2

Maria studied a section of the cliffs, and found fossils in each of four strata, labeled A - D in the figure to the left. The rock layers are shown exactly as they were found. Layer A was found at the bottom of the cliff and layer D was found at the top.

Based on the data shown to the right, Maria would be able to conclude all of the following EXCEPT: __________ . (Choose one answer below)

• Whether the coral fossil is older than the sea sponge fossil

• The exact date that the sea sponge fossil formed

• The oldest fossil in the record

• The youngest fossil in the record

Answer explanation

From the information given we do NOT have time frames related to the fossil findings.

Describe how you can determine the relative ages of the fossils in Maria’s rock section. 

• I just guessed

• The oldest fossils are always further down in the ground. The fossils are formed by small particles of rock called sediment building up over time.

• Once upon a time, there was a dragon who wanted to stop breathing fire....

• I would like to be on a beach enjoying the sunshine!

The students collected fossils from the loose rocks on the beach

With the help of the scientists, each student identified their fossils and their age ranges. Their results are listed in the table below.  Selected the name of the fossil(s) in the following time period: 350-400mya  (Note that some time periods have more than one fossil):

• Sharks

• Crab

• Fish

• Starfish

Where is the gap in the fossil record?  Pick one time range-- this one is a little off- maybe even a typo

•      Between  100mya and 300mya

• Between 350mya-400mya

Write the exact definition of strata-- for this Quizizz select the correct definition-- I would write this down =)

• A dating method that lets you know the actual age of a rock!

• The layers in a sedimentary rock, due to different sediments being deposited at different times.

• the action of wind, water, ice or other natural processes that removes sediments from one location and moves it somewhere else
