The Earth has existed in roughly its present form for about 4.5x109 years.
Geologic column is an ordered arrangement of rock layers that is based on the relative age of the rocks. Geologic time is the time IN the geologic column.
in the scope of geologic time, how significant is the presence of humans?
a million or more years
In the order of time.
it was the last time in history that people was still alive and the people was mean to the other people so that's why we can find the geologic core.
A) a millionD. A million or more years
A million or more years best fits the concept of geologic time. Geologic time spans millions to billions of years and is used to describe the immense length of time over which Earth's processes have occurred, such as the formation of mountains, evolution of species, and movement of continents.
Geologic time consists of eons, eras, periods, epochs, and ages. These measure periods of billions or millions of years.
a million or more years
4.6 billion years
4.6 billion years
The Earth's geologic time scale spans about 4.6 billion years, from the formation of the Earth to the present day.
Geologic time is very long, so a million or more years is the best choice.
If your question is when the earth was created, then the answer is 4.6 billion years ago. plate tectonics started to happen a few billion years later when the earth cooled enough to form a crust.
The shortest piece of Geologic time is the Holocene Epoch in the Cenozoic Era>
k = thousands, y = years. 10Ky = 10,000 years
Yes, one million years is a significant period in geologic time. It is equivalent to 1/485th of the age of the Earth (4.54 billion years). In the geologic time scale, it falls within the Quaternary period, which includes the most recent 2.6 million years of Earth's history.
