lake core investigation

zach sax, zach Question: What depth are the most diatoms found at. 10cm or at 80cm. Claim: we found more diatoms at 80cm. there were less diatoms at 10cm

Data: 80cm=16

Reasoning: The sediment that is deeper is older. Which gives more time to collect at the bottom.

Further question: how many more diotoms are at 20cm then 70cm
: what diatoms will you find the most
