An archeologist is digging at a former lake and finds items at the following elevations. Place the items in order from highest elevation to lowest

_

Write the elevation where each item was found as a positive or negative integer:
Arrowhead = _ feet
Fishbone = _ feet
Fish Hook = _ feet
Fossil = _ feet
Pottery = _ feet
Shell = _ feet

Fossil > Arrow Head > Pottery > Shell > Fishbone > Fish Hook

Step-by-step explanation:

Arrowhead = ___20___ feet

Fishbone = __-10___ feet

Fish Hook = ___-40__ feet

Fossil = __30___ feet

Pottery = ___10___ feet

Shell = 0___ feet

If something is above sea level, it would have a positive elevation, and if below sea level, a negative elevation.  And at sea level, you have 0 elevation.

After this, just put them in order of decreasing elevation.  So, the highest elevation is  30ft with the fossil, then 20 with the arrow head, pottery at 10, shell at 0, fishbone at -10, fish hook at -40.
