Introduction The degree of tombstone weathering is figured to rely on various factors given that the some tombstone stayslonger than others do. One of the major the factor that can be measured effectively is the age of the gravestone. Through calibrated relative dating, that involves dating them relative to each other, the age of the tombstones can be arrived at. Other factors that affect weathering degree of a tombstone include type of rock, height, length and thickness. Through exploring these factors, the knowledge about the degree of weathering on tombstones is established. Further, a model for predicting age can be succinctly tested based on weathering degree.
As the result of the above concepts, this lab was specifically designed with the major objective of measuring the degree of weathering on tombstones.
The specific goals:
Understand how calibrated relative dating works
Understand hypothesis testing. Formulate new hypotheses
Observe/measure the degree of weathering on tombstones of varying age
Develop a model that uses weathering to predict age
Understand and explain sources of error in your model
Hypotheses
The degree of tombstone weathering is related to tombstone age
The degree of tombstone weathering relies on the height of the tombstone
The length of tombstone determines the degree of the tombstone weathering.
Methods
Apparatus
Measuring tape, slide calipers, notebook, writing utensils, computer, Microsoft Excel, hand-held or online calculator, printer
Procedure
The class split into three groups and recorded the varying degrees of weathering for different tombstones at the Murray Cemetry. The characteristics of the 20 tombstones were recorded by each group. The characteristics recorded for each tombstone include height, width, length, name, thickness at bottom and thickness at top, texture, lithology, tilt and visual weathering class. The data obtained were entered into an excel spreadsheet as shown in the result section.
Results
Figure 1: weathering class vs age
As shown in the above the graph, with the help of a best fit line, there is a general trend observed between weathering class and age. A positive gradient indicates that there is a positive relationship between the two and as the age increases so does the weathering class of tombstone increases.
Further, a graph of the weathering class vs height was also plotted as follows:
Figure 2: weathering class vs height
As shown in the graph, there is a general trend between weathering class and height of the tombstone. The equation gives a positive gradient, showing that as the height increases there is a positive effect on the weathering class. The weathering class increases with increase in height.
Next, a graph of weathering class against length was plotted to determine how length affects weathering degree.
Figure 3: weathering class vs length

A line of best fit, as shown in the graph, indicates that there is a considerable relationship between weathering class and length. The graph shows that an increase observed in length leads to an increase in weathering class. The positive gradient shows that there is a positive relationship between the two.
Discussion
The results obtained were able to support the initially listed hypotheses. For age, there was observed consistency in its relationship with weathering class as shown in the graph. Hence, from the methodology used, the hypothesis “The degree of tombstone weathering is related to tombstone age” is sufficiently supported because there was observed consistency with a positive gradient. The results supported hypothesis two which stated that “The degree of tombstone weathering relies on the height of the tombstone” given that there was a general trend. It was shown that the degree of weathering increased with increase in height. The same was detected as shown in the graph, which supported the fact that length is factor in determining the weathering degree. The results show that that an increase observed in length leads to increase in degree of weathering.
Intuitively, the above model has proved successful in predicting the age of a tombstone. In which case, weathering class can be used sufficiently in determining whether a tombstone is young or old. As weathering degree increases the implication is that age will also be increasing. The older tombstone have more weathering degree than the younger tombstone.
However, the lab may have been ineffective and filled with errors, especially when supporting the first hypothesis. The error arose when rating the ages based on weathering classes. Some old rocks were given high ratings while some newer rocks were given low ratings hence leading to the observed inconsistency. This inconsistency may be contributed to randomness used when choosing the tombstones. Consistency can be assured by making use of age groupings at intervals.
Conclusion
From the lab, it was observed that the degree of tombstone weathering relies on the height and the length of the tombstone. The results also proved that weathering degree can be used as model for predicting age of a tombstone. Read More

... 13 Mar. 2008 FLUVIAL GEOMORPHOLOGY INTRODUCTION Geomorphology is the study of landforms and the processes that shape them. Fluvial Geomorphology is the study of role of rivers in forming the morphology of the earth. In short it is the study of landform evolution related to rivers. Rivers are significant geo morphological agents, they show an amazing diversity of form and behavior and transfer water and sediment from the land surface to the oceans. Highly dynamic in nature, river channels adjust and evolve over timescales that range from hours to tens of thousands of years or more and are found in a wide range of environments. An understanding of fluvial geomorphology has proved its use in channel preservation, environmentally sensitive...

Geomorphology

This paper explores the process of geomorphology.
The processes of the surface are made up of wind, water, fire, ice, and living things on the earth surface. The chemical reactions forming soils and altering the stability, material, and topographical rate of change under gravitational force are some of the surface processes. These factors are strongly affected by climate. The geological processes are the mountain range uplift, volcanic growth, isostatic changes in the elevation of land surfaces, sedimentary basins formation are also surface processes. The surface of the earth together with the topography form an intersection of climatic, biologic, and hydrologic action with the processes of geology.
The huge topographies f...

This problem affects many Americans. The term ‘IPV’ can be used to describe the sexual, physical, or psychological harm from a former or current spouse or partner. The violence can happen in same sex or heterosexual couples and does not need any sexual intimacy. The four types of IPV include physical violence, sexual violence, emotional or psychological violence, and threats of sexual or physical violence.
These definitions are important because they help in monitoring the IPV incidences and examining the trends for certain duration of time. The definitions help in determining the potential of IPV and making the comparison of the problems in the whole jurisdiction. Fine definitions assist researchers in measuring the protectiv...

... mantle, rising if material such as an ice cap is removed and sinking if material is deposited. Isostacy is seen in areas in which ice bergs have melted since the formation of ice bergs can lead to sinking of the earth’s surface. Retreating of the ice bergs leads to the reduction of the load on the lithosphere and the asthenosphere and they move back to their equilibrium levels. 3. Why do the erosion of mountains eventually expose the underlying basement rocks? Continuous erosion of mountains washes away all the soil and rock particles that forms the mountains. They are washed to the lower valleys leading to exposure of the underlying basement as the mountains are gradually reduced. 4. Can you draw a cross-section of Earth on the board...

... Introduction The onset of radio-carbon dating has made it possible to precisely determine the age of an organism which formerly lived. Through taking the ratio of carbon-12 to carbon-14 in a particular sample and then benchmarking it to the living organism’s ratio, an individual is able to determine the age. In which case, another important aspect applied is half-life, which is the time taken by half of the sample to decay and is denoted by t1/2. Objective This lab was designed specifically, with a major objective of developing a more comprehensive and hands-on understanding of radiocarbon dating. From this, the specific goals are as follows: Understand half-life and radio-carbon dating Know the difference between radiocarbon ages...
