Question

Explain how the rock layers support the time when Tyrannosaurus rex and mammoths existed.

Answer 1

Explanation: Tyrannosaurus rex lived in the late Cretaceous period. According to the chart and the geological time scale, mammoths lived in the late Cenozoic era. The rock layers support this fact because the mammoth is in the top layer. So, the mammoth fossil formed more recently than the T. rex fossil. This information also indicates that Tyrannosaurus rex and other dinosaurs lived before mammoths.

Answer 2

The importance of rocks has been realized on the surface of earth since a long time because they provide information and knowledge about the surface on which they are found.

They also tell us about the species which are found on that place where these rocks are which gives a lot of knowledge to the scientists. Also these layers have minerals in them which are very important for the animals to have a healthy life and also the water present in them naturally.
