30 POINTS PLEASE HELP
1. Name two possible causes of the largest mass extinction in Earth’s
history and explain how this both helped and hurt different species.
2. In 3-5 sentences, explain the major developments and events of the
Mesozoic Era.
3. In 3-5 sentences, explain the major developments and events of the
Cenozoic Era.
If you answer all three I will give brainliest.

1. Two possible causes of the largest mass extinction aka the Permian-triassic in earth's history is asteroid impacts and massive volcanic eruptions. this hurt because of how it destroyed the land and killed some animals and people. it helped us because the emerging supercontinent of Pangaea showed severe extremes of climate and environment because of its great size.

2. The major developments of the mesozoic era all of Earth's mainland same together into the supercontinent of Pangea. The cleavage began with intercontinental separation during the Late Triassic. Pangea had fractured into various subcontinent during that time as well.

3. The Cenozoic Era was divided into 2 periods which wer, the Paleogene and Neogene which are divided into ages. The Cenozoic had seen the extinction of the not bird dinosaurs. They also witnessed the rise of homo sapiens. It is noticeable by the Cretaceous-Tertiary disappearance event at conclusion of the Cretaceous period and the end of the Mesozoic Era.

I had fun finding these parts and putting them together. it's always good to learn something new! i'm glad i'm not too late ♡

The two possible causes of the largest mass extinction on Earth were volcano eruptions and asteroid collisions.

The Geologic Eras

1. The asteroid collisions and volcano eruptions are the causes of the largest mass extinction on Earth.

The disruption on Earth created the largest mass death, which wiped out plants and animals.

2. The developments of the Mesozoic Era were the Triassic and Jurassic, as its the age of dinosaurs.

Flowering plants emerged during this period.

The era ended with a massive meteorite collision that caused a mass extinction.

3. The Cenozoic Era saw the age of mammals.

Earth's climate became cooler and drier, allowing many plants and animals to evolve.

The changes are seen in the evolution of life. One example is the had evolved of Homo sapiens.
