Geological Event Timeline

Today, the earth has given humans and animals the ability to live peacefully. However, fossil fuels and greenhouse gases are always being excreted through the air and the earth may not be able to give the resources we need, if people continue to trash the environment.

Our mothers had given birth to us 14 years ago, and we have been introduced into this extraordinary world.

A massive sheet of ice covers up most of northern United States.

Fossils appear in Ethiopia and are from the homo erectus age. 

The Pleistocene ice age gets under way and begins. This is the most recent ice age.

The formation of the Grand Canyon is under way and begins.

The primitive monkey or apes have evolved into extraordinary mammals.

Around 65 million years ago, the dinosaurs finally become extinct. Most scientists agree that a meteor wiped them all out. 

Angiosperm flowers began appearing. These flowers reproduce with male and female reproductive parts just like students learn today. 

The first mammals start to appear after the extinction. This is most likely due to the lack of predators that can eat the tiny mammals and how the mammals finally started to evolve. 

A huge mass extinction occured and wiped out 95% of the living organisms.

Suprisingly, the first insects with wings evolved 300 million years ago. 

458 million years ago, the oldest and first land plants are around.

510 million years ago, the oldest fossil fish had been around.

Due to massive amounts of greenhouse gas and carbon being released, a massive volcanic eruption hits the earth by storm and heats up the frozen earth 640 million years ago. 

About 650 million years ago, the continents of earth became massively frozen. People refer this period of earth as "snowball earth."

About 1,500 million years ago, the eukaryotic cell organisms start to develop. These are multicelluar organisms. 

The first ozone layer or oxygen filled atmosphere form 2,000 million years ago. 

Prokaryotic cells and organisms start to appear 3,500 million years ago. These are single celled organisms. 

The first and oldest evidence for life as we know it was 3,800 million years ago.

The oldest crustal rocks are found and dated around 3,900 million years ago. 

The planet earth as we know it had been formed about 4,600 million years ago. Most scientists believe in the Big Bang theory for the formation of our interesting planet.
