1. Which of the following statements accurately describes the development of the geologic time scale?
a. Scientists developed the geologic time scale by studying rock layers and index fossils worldwide.
b. Scientists developed the geologic time scale using fossilized remains from Europe and Asia.
c. The geologic time scale was developed so scientists could put Earth's rocks in order by absolute age. *******

I'm failing I need help badly! I don't need answers. Just help.
Ms. Sue are you sure?
To determine which statement accurately describes the development of the geologic time scale, we need to consider the methods and purpose of its creation.
a. Scientists developed the geologic time scale by studying rock layers and index fossils worldwide.
This statement is true. One of the primary methods used to develop the geologic time scale is the study of rock layers and fossils found in different parts of the world. By comparing the sequence and characteristics of rock layers and the fossils contained within them, scientists can determine the relative ages of the rocks and establish a timeline of Earth's history.
b. Scientists developed the geologic time scale using fossilized remains from Europe and Asia.
This statement is not accurate. While fossils from Europe and Asia have contributed to our understanding of Earth's history, the geologic time scale is not limited to these regions. Fossil evidence from all around the world has been used to develop the time scale.
c. The geologic time scale was developed so scientists could put Earth's rocks in order by absolute age.
This statement is the most accurate description. The main purpose of the geologic time scale is to organize Earth's rocks and geological events according to their absolute ages. By using various dating techniques, such as radiometric dating, scientists can assign numerical ages to different geological periods and epochs, allowing for a more precise understanding of Earth's history.
d. The geologic time scale shows how much all of the animals weigh that have lived on Earth.
This statement is not accurate. The geologic time scale does not provide information about the weight of animals that have lived on Earth. Its primary purpose is to provide a framework for understanding geological time and the evolution of life forms throughout history.
Therefore, the correct answer is c. The geologic time scale was developed so scientists could put Earth's rocks in order by absolute age.
