Gravestones provide clues to climate history

11.12.09

By convocation volunteers' measurements of marble gravestones of different ages around the world, scientists hope to produce a unbelievable map of the weathering rates of those gravestones and thereby better understand how the atmosphere has been changing. The study, called EarthTrek, is developed and managed by the Geological Civilization of America 's (GSA) Education and Outreach group in partnership with organizations around the globe.

GSA says the weathering rates of gravestones disclose changes in the acidity of rainfall between locations and over time. The acidity is affected by air pollution and other factors, and could be used as a rule of changes in climate and pollution levels.

This project has been divided into two levels of data collection. The first is the Graveyard Facts level (the location of graveyards) and requires volunteers to log GPS coordinates. The second level - Gravestone Data level off (the measurement of the weathering of marble gravestones) also requires a micrometer.

How do you calibrate a standard micrometer?

Apr 18, 2008 by Longhorn | Posted in Maintenance & Repairs

I know how to read them, but how do you "zero" can, if they made the adjustment? I know that it involves small spanner wrench, but I can not find a website or information on proper calibration. I refer to the old style "thimble" Art of the micrometer.

This is an excellent question. We use the micrometer
must be calibrated to produce exactly the engines. We
a company do to us, they use a "standard" that an object
they know that exactly a certain size, and they use to
Adjustment of the caliper.

What is more accurate, the vernier caliper reading or the micrometer caliper reading?

Jun 22, 2008 by Donkey_Kong | Posted in Physics

What is more accurate reading of the caliper or micrometer caliper reading?
How would you know that the instrument is mre accurate than the other when looking at their least expect?

The caliper can read up to 0.01 cm and the micrometer caliper can read up to 0.001 inch (0.01 mm).
as the micrometer is more accurate.

Look at the number of decimal places that they can be up to in the same unit. In the above reasons, the measure can be micrometers to 3 December Villages in cm, as compared to 2 December Villages in cm, for the calipers.
