Radiometric dating of sedimentary rocks is unreliable because introvert dating uk
Because of these assumptions, radiometric dating can seem mathematically accurate, yet far from fact on actual age.
When building a brick wall, we start with the bottom layer and work our way up with successive layers.
Sedimentary rock is one of three main groups of rock, the others being metamorphic and igneous rock.
Scientists have recently discovered that mud particles in rapidly moving water can clump together (as floccules) and be quickly laid down in multiple layers. Andrew Snelling, a geologist and researcher for Answers in Genesis, gives the following six evidences for Noah’s flood: Scientists used radiometric dating of meteorites to come up with the estimated age of the earth—4.5 billion years. Radiometric dating involves estimating age by measuring the ratios of two related chemical elements—one that is decaying into another. Each element has a set number of protons and electrons in the atom. Certain isotopes like carbon-14 are unstable, or radioactive.
Another choice is granite, which forms as magma cools underground.
These molten rocks are classified as igneous rocks.
Similarly, when we look at rock layers, such as in the Grand Canyon, the layers are ordered in succession from the oldest layer at the bottom to the newest layer on top, which is called the principle of superposition. So what about the lowest rock layers in the geological record, such as what we find at the bottom of the Grand Canyon?
They are designated as having formed in the Precambrian time period.
