Explain why Earth and other planets were not solid when they formed during the
beginning of the Precambrian, approximately 4,600 million years ago (MYA). What was
this particular time period called, and why is this time period not really considered a part
of Earth’s geological history?
helpful links and hints please
Oh, surely these are all given to you in your text or study materials, whether in print or online. Please double-check everything in the unit you're studying. The answers should be in there.
I Googled "timeline after the big bang" and found this but it wasn't the only site. You can do the same.

I agree with writeacher that it is in your reading material. And you could do what I have done and search the web. That timeline I gave you gives you the name. But you didn't see that. Did you read it? Here is another site. There are numerous sites you cn get by typing "what is the name of the precambrian era"
Wikipedia has a good article that gives you the name. Here is the one from MSU.

You can find information about the era under "big bang theory" that will give you information about the nature of the gases at that time period and how those gases formed the elements, especially those from hydrogen to iron by the process of fusion. Good luck.
During the beginning of the Precambrian era, approximately 4,600 million years ago, Earth and other planets were not solidified. This period is often referred to as the Hadean Eon. The Hadean Eon is characterized by intense heat and extreme conditions, making it not part of Earth's geological history in the traditional sense.
To understand why Earth and other planets were not solid during this time, we need to explore the early stages of planetary formation. The formation of planets begins with the accumulation of matter in a disk-shaped cloud called a protoplanetary disk. These disks consist of gas, dust, and various materials.
Here's how you can delve deeper into this topic:
1. Visit relevant websites: Access reputable scientific sources such as NASA's website, the Smithsonian National Museum of Natural History, or academic research papers for detailed information on the subject. Search keywords like "Hadean Eon" or "planetary formation" to find specific articles.
2. Research early Earth formation: Study the processes involved in the accretion of matter during the Hadean Eon. Look for resources that explain how dust and gas particles gradually formed larger bodies, eventually culminating in the formation of planets.
3. Investigate heat and extreme conditions: Explore how intense heat and extreme conditions during the Hadean Eon contributed to the lack of solidification. Look for explanations regarding the high temperatures and violent processes like impacts and volcanic activity that characterized this era.
4. Study geological evidence: Look into the geological evidence from the Hadean Eon, such as zircon crystals found in Western Greenland. These crystals provide insights into the initial stages of planetary formation and the subsequent cooling of Earth's crust.
Remember, the early stages of planetary formation are complex and ongoing research helps refine our understanding. Continue to seek up-to-date sources and scientific papers for the most accurate information.
Additionally, consult with experts in the field of planetary science or geology who can provide firsthand knowledge or direct you to further resources.
