How much has the depth of the lettering been reduced on each tombstone?
The depth of the lettering been reduced on each tombstone if the average rate of chemical weathering of carbonate rock in an urban area is
Answer to Problem 2PEB
Solution:
Explanation of Solution
Given data:
The average rate of chemical weathering of carbonate rock in an urban area is
The depth of lettering of the tomstones shown in the following table was measured by 2010.
Formula used:
Write the weathering rate is divided by the surface reduction by the age of the tombstone.
Explanation:
Recall that the weathering rate is divided by the surface reduction by the age of the tombstone.
Rearranged:
For date of tombstone 1920 and age
Substitute
For date of tombstone 1921 and age
Substitute
For date of tombstone 1948 and age
Substitute
For date of tombstone 1958 and age
Substitute
For date of tombstone 1975 and age
Substitute
Conclusion:
The depth of the lettering been reduced on each tombstones are

- A specimen of shale has a mass of 17.25 g dry and 22.24 g wet. The volume of the specimen is 12.15 cm3. What is the porosity of the shale?arrow_forwardRates of tectonic uplift can be determined from the age and elevation of stream terraces, flat-surfaced deposits of streambed sediment that represent ancient floodplains. By dating the age of the terraces and measuring the elevation of the terrace, the uplift rate is the difference in elevation of the terraces divided by the difference in ages of the terraces. A terrace at 164 m elevation is 101,000 years old while another terrace at 111 m is 24,800 years old. What is the ratearrow_forwardWhat is the bulk density of the dry soil?arrow_forward
