Also shown below (click for a larger version) is a photo of the paleosol taken from the other side of the road. 100 dpi photo of the same outcrop taken from the opposite side of the road showing from bottom to top (regolith of Butler Hill Granite, dark paleosol formed on top of the granite, shaly Lamotte Formation (basal), Lamotte sandstone (top). Science has determined the age of the Earth to be 4.54 /- 0.05 Ga As mentioned in the opening of this article, there are at least three pieces of independent evidence that argue strongly against a young earth stance.
I will deal with each of these issues in this essay and answer some of the ye-criticisms.
If a number of samples are analyzed and the results are shown to define a straight line within error, then a precise age is defined because this is only possible if each is a closed system and each has the same initial ratio and age.
The uncertainty in determining the slope is reduced because it is defined by many points.
Many radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughter-type isotopes already exists.
These isotopes did not come from radioactive decay in the system but rather formed during the original creation of the elements.
The incremental additions of the daughter type can then be viewed in proportion to the abundance of parent atoms. It has already been shown—7—that the number of daughter atoms present from radioactive decay , is called the initial ratio.
(b) Unconformable- Layers experienced weathering/erosion during deposition, leading to uneven layering Intrusions Faults An unconformity is a buried erosion surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous Nonconformity- Two different rock types making a contact Disconformity- Same rock type making contact Angular Unconformity- Rocks contacting at a tilt or angle Depending on rock type (composition) and climate, rocks vary in their resistance to weathering.
In the arid environment of the Grand Canyon, shales and other finer-grained sedimentary rocks weather easily and form talus slopes with lots of weathered material, whereas sandstones and limestones are more resistant and commonly form cliffs.
Figure 1 schematically illustrates these three processes.
Potassium (K), along with lithium (Li), sodium (Na), rubidium (Rb), and caesium (Cs), is an alkali metal that reacts violently with water, air, and the halogen elements (fluorine, chlorine, bromine, iodine, and astatine).
