Statement of the problem situation:
- Is the appearance of the earth’s surface of our country, its nature, random?
-Have they always been like this?
-If not, how and why did they change?
-How did scientists prove that nature was constantly changing and developing?
We have to answer these questions. Be careful.

1. Introduction “People guessed that the nature of the Earth was not always the way people see it when they encountered fossils, plants and animals that no longer exist, and shells. Gradually, the science of ancient life—paleontology—was formed. What are the names of scientists involved in this science?
For many years, scientists around the world have been studying the preserved remains of animals and plants found in strictly defined layers of rocks. This means that the development of nature is inextricably linked with geological development, so they must be considered in unity. Currently, scientists have reconstructed a picture of the Earth's past by creating a geochronological table.
Determining the age of rocks allows us to establish the relative and absolute time that has passed since some moment or event in the history of the Earth. If the occurrence of rocks is not disturbed, then each layer is younger than the one on which it lies. The topmost layer was formed later than all those lying below. The time during which each group of rocks accumulated is called an era. Era name reflects relative time
– How is the absolute age of rocks determined?
Absolute age is the time elapsed since the rock was formed. It is determined by radioactive elements - for example, uranium. The rate of its decay is known and always remains unchanged (uranium decays into helium and lead, helium is seeded, lead remains) by the amount of lead the age of the rock is determined
Conclusion : Rocks are witnesses to the evolution of life
2. Working with a geochronological table pp. 34-35
Individual work turns into group work: students write down everything they know on this topic, or can extract from the table:
Which graphs stand out in it?
Read the names of the periods of each era from the oldest to the youngest.
What was the longest era in Earth's history?
Which periods were the longest?
Which period is the shortest?
What changes occurred in nature in each era?
What is the name of the era and period in which we live?
They exchange baskets, read and discuss.

Group 2 – Paleozoic era
Group 3 – Mesozoic era
Group 4 – Cenazoic era
Using atlas maps, a geochronological table and the textbook text, answer the questions and complete tasks on the contour map:
