How the Earth Was Made - Aminata's Project Reflection

Evolution

This is how the earth was made in 4.5 billion years ago earth was a big ball of fire and lava it was made of millions of meteors. Earth was a molten ocean it was made of hot lava then the earth began to solidify, earth was as hot as the surface of the sun. The earth’s oceans arrived from above extraterrestrial meteors the material from which the earth was formed. Water come from space and changed the planet dramatically. The result would be a water world. Granitoid protocotinents grew larger. They would form the hearts of major landmasses. The dominance of the oceans was over – the continents arrived and when we had more and more O2. The sky and oceans changed from green and red to blue. The continents moved together because of plate tectonics, making super continent Rhodinea. Rhodinea’s huge size blocked the warm ocean currents from the equator. The cold temperatures froze the Earth and created Snowball Earth – Earth was frozen solid, lifeless like a frozen desert. Volcanic eruption broke rhodinea apart. CO2 from the volcanoes created global warming which melted the frozen earth. Now life could finally exist. Many organisms lived and died for example the dinosaurs. In order to evolve organisms must adapt to climate and changes in their environment. So far, human have adapted to ice ages conditions, but we have live for only a fraction of fraction of 1% of Earth’s history.

What I learned from our project

Earth is 4.5 billion years old.
At 4.5 billion years ago, Earth was a big ball of fire and lava
Earth was as hot as the surface of the sun.
Earth was covered in thick blanketing clouds of water vapor that condensed in the atmosphere to trigger the greatest downpour the earth would ever see. It rained for million and million years.
The rain began to form the oceans small volcanic islands stuck out of the new oceans
The Earth was formed by millions of collisions of meteors.
Earth had huge green oceans because they were iron rich from volcanism and a red sky because there was no O2.
The earth oceans arrived from above, water came from space.
Water changed the planet dramatically
Continents were born from millions of years of volcanic activity.
Earth was once made entirely of granite and water.
The oceans changed from green to blue.
The sky changed from red to blue when oxygen from stromatolytes filled the air.
Earth was once a snow ball, all covered with ice.
Continent are always moving.
Super continent were formed by colliding tectonic plates. This is how we got mountains.
When earth was a snow ball it felt desolate life less place.
Now that we have iron rich and O2 life can finally exist.
Volcanic activity split the super continents apart
Africa and South America were stuck together.
Listening and taking notes
How to scale a time line
How to solve Proportion
To work in group
The planet earth will die in plus 2 billion years in the future.

What I dislike in our project

That earth was a big ball of fire and lava.
Earth was as hot as the surface of the sun.
Earth was hot over 200 deg F.
That the oceans were green and the sky was red.
The earth was a like a snow ball.
Earth was a desolate lifeless place.
Life started deep down in the oceans.
Human are a fraction of fraction of 1%of earth’s history.
The planet Earth will die.
Humans are ruining our environment by causing climate change from greenhouse gas emissions.

What I liked in our project

When it started raining
When the oceans were formed
It rained for million and million years.
The blue sky and blue oceans
The water world
Water changed the dramatically
When continent arrived
When Africa and South America was stock together
I enjoyed making our class timeline.
I also liked using proportions to create our project to scale.
