These three different methods are: 
Radiation Measurement

Strati-graphic Superposition 

The Fossil Record

Finding certain isotopes like carbon-14, and etc. can reveal the true age of a certain rock]]> 2017-03-09 19:14:50 UTC https://padlet.com/denislav_kasaivanov/mt36aqtcig93/wish/159098541 denislav_kasaivanov https://padlet.com/denislav_kasaivanov/mt36aqtcig93/wish/159098743 http://www.dnr.louisiana.gov/assets/TAD/education/BGBB/1/measuring.html

"Down" is older, "up" is younger. The principle of inclusion - a structure that is included in another is older than the including structure. Using these terms here, scientists have been able to estimate the age of certain rocks, some dating to hundreds of million of years, to find out the true age of certain rock formations, and how old the Earth is in total.]]> 2017-03-09 19:19:58 UTC https://padlet.com/denislav_kasaivanov/mt36aqtcig93/wish/159100622 denislav_kasaivanov https://padlet.com/denislav_kasaivanov/mt36aqtcig93/wish/159102185 As you may know, Fossils are abundant in the Earth's crust. Some of the earliest fossils even taught us what kind of animals have roamed the Earth during its earliest stages. The same thing can go for how old the Earth actually is. The oldest fossil ever found dates back to 3.7 billion years back, which already drastically debunks the 7,000 year old Earth theory. These kinds of fossils can truly tell us that the Earth is way older than we think it is, but still relatively young as a planet.]]> 2017-03-09 19:24:16 UTC https://padlet.com/denislav_kasaivanov/mt36aqtcig93/wish/159102185
