Question

Geologic time:

Answer 1

Answer:

The largest period of geologic time of the Phanerozoic eon

Explanation:

• This eon starts after the Precambrian period, this is the current period with an abundance of plants and animals that existed covering about 541 million years.

• It began with the Cambrian period when the first fossils started to emerge in hard shells. The evolution and development of plants and animals, insects and emergence of land plants took place also during this period the tectonic plates were moving due to the collision of the crust and mantle,

• This period was later divided into Paleozoic, Mesozoic, and Cenozoic, and these further subdivided into 12 small zones. Paleozoic featured the rise of the rising of fish, amphibians, and reptiles.  

• The quaternary period marks the last period of phanerozoic eon with a span of 2.58 years only it's divided into Pleistocene and the Holocene.

• Relationship with earthquakes, fault, and energy is simple as the seismic energy that moves from the earth crust in the form of waves of P, S, and L shaped format creates tremors and large shaking and brake opening of the ground by fissure types of eruptions leads to faults that are due to the folding and molding the earth crust in mantel.
