A new geological model, the most detailed ever, allows us to peer into the past and see what the Earth looked like 100 million years ago.

The new model will allow us to better understand the structure of the Earth today.

And even understand how it will look in the future.

The geographic models that have existed until now have not allowed scientists to fully understand how the current surface features of the Earth were formed.

"To predict the future we must first understand the past," explains Dr. Tristan Sayles from the University of Sydney in Australia, who was one of the leaders of the study.

The model presents an unprecedented resolution of 10 km, during 100 million years, which is divided into stages, each of which is a million years old. The new model will allow geophysicists a more complete and dynamic understanding of the Earth's surface. For example, explains the leader of the study, he Records the dynamics of the movement of sands from the land to the sea. In ways that we did not know before. This is the movement of rocks that crumbled into dust over millions of years. This movement. has a role in regulating the Earth's carbon cycles, and the discovery has an impact on the understanding of climate change. The new geological model will

allow Scientists also have to test different theories about the response of the Earth's surface to future climatic developments, possible tectonic changes as well as the effects of other evolutionary developments.
