4 types of absolute dating correct answers 1. C-14 2. Tree Ring 3. Archaeomagnetic 4. Obsidian Hydration half life of C14 correct answers time required for half of the carbon-14 available in an organic sample to decay (5370yrs) what can you date for C-14? correct answers any organic material -once alive or byproduct of living thing how C-14 dating works correct answers -anything that's alive takes in C-14 -C-14 is an isotope and loses 2 neutrons to C-12 -when something dies, it ...

Earth Science Lab Final (Answered) Complete Verified Solution Noncomformity 1) Younger sedimentary rocks on top of older metamorphic or intrusive igneous rocks 2) Imply period of uplift of deeply buried rocks Three types of uncomformities angular uncomformity, disconformity, and noncomformity Radiocarbon dating Using the carbon-14 isotope to date very recent events (Half-life of carbon-14 is only 5,730 years) (Only useful for dating events from historic past and very recent geolog...

Atomic Structure An atom is a complex arrangement of negatively charged electrons arranged in defined shells about a positively charged nucleus. This nucleus contains most of the atom's mass and is composed of protons and neutrons (except for common hydrogen which has only one proton). All atoms are roughly the same size Protons Positively charged particles found within atomic nuclei Neutrons A subatomic particle of about the same mass as a proton but without an electric charge, present i...

WGU C389 - Science, Technology, and Society. Questions and answers, Questions and answers, rated A+ I.e. How old is the Earth? - -Focuses on the natural world I.e. Can we analyze the atoms with radiocarbon dating to determine the age of the rocks? - -Uses testable ideas I.e. Other scientists challenge the current age of the earth when they discover new evidence or processes for determining age - -Involves the scientific community I.e. Objects found in nature such as fossilized organi...
