Answer:
Check if the rock layer has fossils in it.
Explanation:
The rock layer from the inside out and the fossils will tell you how old the rock is.
The fossil symbols and mountain belts were helpful because it showed where the land and water dinosaurs were able to live, especially with the non-swimmers in Africa and South America. There is proof of some mountains matching in Western Europe and Greenland.
Mountain slopes have faster erosion because it is easier for fast moving bodies of water to carry down eroded material downhill, rather than across flat land.
Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or <em>"geochronologic"</em> time scale. The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.
