What is the limitation of relative dating

Relative dating can only tell you which strata are older or younger than others. The dates are floating, and are in need of anchoring. That is where absolute dating, using radiometric dating techniques for example, come into play. They can fix certain of the strata at particular age, anchoring them solidly and leaving far less leeway for those strata above and below them, and especially for strata sandwiched between two absolutely-dated strata.

To understand how our world is evolving, scientists use computer programs called climate models to forecast future climate. Climate models function in the same way that a computer lab does. Climate models are computer programs that scientists use to analyze how our world is changing.
