• Erosion and Mass Wasting

  There are two types of weathering, mechanical and chemical. Mechanical weathering is a gradual physical process from rock to clay, caused by hot and cold weather expanding and shrinking rocks to cause cracks.

• What are some factors that influence soil formation?

  Cold climates are also more susceptible to freeze-thaw and wetting-drying behavior, increasing the amount of physical erosion and weathering.

• Mechanical and Chemical Weathering Processes

  Weathering results in either fracturing or abrasion e.g. like the difference between a hammer and sandpaper (2).

• Origin of rocks and rock sequences

  Deposition of limestone ? A time gap in deposition ? Uplift, weathering and erosion ? Folding of shale ? Metamorphism of shale ? Intrusion of granite pluton ? Deposition of shale oldest 3.

• Roles of Weathering in Different Climates.

  For example, the products of weathering are a major source of sediments for erosion and deposition in all climates, although differentially.

• Distribution of Different Seafloor Sediments

  (locally weathered from underlying rocks); (4) relict (remnants of earlier environments of deposition, for example, deposits formed during the transgression leading to the present high sea level stand); (5) detrital (products of weathering and erosion

• Climate Change and Mechanical vs. Chemical Weathering

  The warmer climate would result in enhanced growth of vegetation, but even low elevation vegetation and shrubs take a while to grow large enough to stunt physical erosion.

• Relative Dating Methods

  Uplift, weathering and erosion then cause the deposition of limestone (chemical weathering and the principle of superposition and principal of original horizontality). Once again, the limestone is subject to uplift, weathering and erosion.

• What is the F-Test, with regards to variances in populations being the same?

  and conclude that there is statistically significant effect of weathering on the radioactivity.
