Which of these CANNOT be used as evidence to reconstruct the early history of Earth? 2. Which type of data from Table 1 provides the best evidence that Earth formed along with the rest of the solar system about 4.6 billion years ago? 3. Explain why the moon has millions of craters while the Earth only has 128 based on Table 1 and Earth's geologic processes. 4. What is the significance of Zircon in understanding geological events?
Understand the Problem
The question is asking to evaluate evidence for reconstructing Earth's early history based on provided data, understand implications of the data on the formation of Earth and the moon, and explain geological differences using information from the table.
Answer
1. The average temperature of solar system objects. 2. Age of the oldest minerals. 3. Tectonic plate activity erases craters. 4. Zircon helps date geological events.
- The average temperature of the solar system object's surface cannot be used as evidence to reconstruct the early history of Earth. 2. The age of the oldest minerals on Earth and the Moon provides the best evidence for Earth's formation about 4.6 billion years ago. 3. The Moon has millions of craters while Earth has 128 due to Earth's tectonic plate activity and erosion processes that erase craters. 4. Zircon is significant because it contains uranium, allowing precise dating of geological events due to uranium's decay into lead.

More Information
Zircon crystals are key in radiometric dating, offering a timeline for Earth's crust formation due to their stability and uranium content.
Tips
Confusing evidence types like temperature with radiometric dating can lead to incorrect assumptions about Earth's history.
