It is false that scientists are able to determine the relative age of rocks in specific years. This is because relative age refers to how much <span>one layer is older or younger than another layer but does not indicate the rock's age in years, but perhaps in centuries at most. Scientists can, however, determine the absolute age of rocks using radiometric dating. </span>

Education is the backbone of our future as a society of growth in all things that will make life better. If we as a society don't take the education of our youth seriously, we are practically ruining our future. Education gives us knowledge of the world around us. It develops a new perspective of viewing life. Imagine a world of politics with uneducated people. Imagine a government without educated rulers... looking at history with a knowledgable perspective helps make good decisions. A wise man once said, "Those who Do Not Learn History Are Doomed to Repeat it" (George Santayana).

And they move due to the force of gravity!
The block mountain (horst) is left standing higher above the sunken graben!
