Final answer:
The most widely accepted age of the Earth by the geologic community is: 2. 4.6 billion years
The correct option is 2.
Step-by-step explanation:
The estimated age of the Earth, widely accepted by the geologic community, is approximately 4.6 billion years.
This age is determined through various scientific methods, including radiometric dating of rocks and minerals. Radiometric dating involves measuring the decay of radioactive isotopes within these materials to calculate their age.
The 4.6 billion-year figure is based on evidence from a variety of sources, such as the ages of the oldest rocks on Earth, the ages of meteorites, and the ages of Moon rocks brought back by Apollo missions.
Over the years, advancements in dating techniques and a comprehensive understanding of Earth's geology have contributed to the refinement of this estimate.
The other options provided (1 trillion years, 100 million years, 35 million years, and 157,000 years) are not consistent with the widely accepted scientific understanding of the Earth's age based on geological evidence.
The most widely accepted age of the Earth by the geological community is 4.6 billion years. Therefore, the correct option is:
2. 4.6 billion years
The correct option is 2.
