What are your thoughts about the geologic time scale and geologic time in general? How easy is it to wrap your head around how long Earth has been around? Did you find any interesting analogies or comparisons for how to picture 4.6 billion years? etc.
You will be picking a period or epoch to research: I picked Permian Period
please answer the following questions about this period:
- What are your thoughts about the geologic time scale and geologic time in general? How easy is it to wrap your head around how long Earth has been around? Did you find any interesting analogies or comparisons for how to picture 4.6 billion years? etc.
- Research the period/epoch you chose. What time period (years) did this period/epoch cover? What werethe major things happening on Earth during those times? What was life like during this time period? etc
“Since you have posted multiple questions, we will provide the solution only to the first question as per our Q&A guidelines. Please repost the remaining questions separately.
Answer 1:
The lengthy period of time filled by Earth's geologic history is known as "GEOLOGIC TIME."
The Archean Eon, which lasted from 4.0 to 2.5 billion years ago, marked the beginning of formal geologic time, which now extends to the present. The informal Hadean Eon, which roughly corresponds to the time between the beginning formation of the Earth (4.6 billion years ago) and 4.0 billion years ago, is frequently included in modern geologic time scales as well. Geologic time is, in essence, the period of Earth's history that is represented by and preserved in the planet's rock strata.
The "calendar" for events in Earth history is the GEOLOGIC TIME SCALE.
Eons, eras, periods, epochs, and ages are the named units of abstract time that are divided up into under this system, in decreasing order of duration. According to stratigraphy, which is the correlation and classification of rock strata, those geologic time units are counted.
The primary method of establishing a geologic time scale, however, is through the use of fossil forms found in rocks. The timing of the appearance and disappearance of widespread species from the fossil record is used to delineate the beginnings and ends of ages, epochs, periods, and other intervals.
