Remember: the principle of superposition refers to lower layers of rock forming first and higher layers forming on top of them later.]]> 2020-05-09 08:51:35 UTC https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561172576 briannaraven98 https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561182373 extra resource]]> 2020-05-09 09:01:48 UTC https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561182373 briannaraven98 https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561192887 Some unstable elements such as Carbon-14 can be used to tell how old fossils are using what is known as their "half life". We measure the rate of decay of the Carbon-14 atom compared to the stable Carbon-12 atom. ]]> 2020-05-09 09:13:09 UTC https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561192887 briannaraven98 https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561194683 2020-05-09 09:14:59 UTC https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561194683 briannaraven98 https://padlet.com/briannaraven98/hmq0vdqi4fbnuaz2/wish/561204821 The principle of superposition states that if undisturbed, due to gravity, lower layers of rock were deposited first and are therefore older.
