The existence of life on earth relies on photosynthesis...this makes me think of Spongebob #BCsci19 #chapter7

[Katie Hack @KatieHack13]

Chapter 7 is all about how life formed from inanimate matter. When it formed, how it formed, the parts of the atmosphere that allowed it to form, and how the earth had to change in order for life to be present on the earth. #BCsci19 #chapter7

The earliest fossils are from 3.5 billion years ago... #woah #BCsci19 #chapter7

[Katie Hack @KatieHack13]

It still blows my mind that life began from little pieces of dust and matter. How is that possible? #BCsci19 #chapter7

[Katie Hack @KatieHack13]

Chapter 5 discusses the way the Earth's (and other planets) atmosphere was created. It is unique among other planets because it's atmosphere changed over time. The origins of our atmosphere and oceans are what set us up for the ride of life. #BCsci19

The atmospheres of Earth and Venus were originally extremely thick with high surface pressures. I am feeling like these two planets right now... I am the planet; school is the extremely thick pressure on the planet (me).

Greenhouse gases act as a blanket that warms the earths surface... COOL! #BCsci19

[Katie Hack @KatieHack13]

Water and Carbon Dioxide began inside of the earth, before they were brought to the surface #BCsci19

[Katie Hack @KatieHack13]

We should create a puzzle of the tectonic plates #BCsci19

[Katie Hack @KatieHack13]

Seismology- tells us information about the earths core #BCsci19

[Katie Hack @KatieHack13]

@MakenzieDav I agree!!

When the book talks about how to weight a planet.....

Chondrites help scientists understand how the earth developed #woah #BCsci19

[Katie Hack @KatieHack13]

I did not realize that light years was a size. The fact that clouds can be 1 to 3 light years across... which is as big as our solar system... #woah #whoknew #BCsci19

[Katie Hack @KatieHack13]

It blows my mind that we live on a giant rock that is billions of years old. #how #Icannotwrapmyheadaroundit #BCsci19

@DumitruHaley Wow, how clever.

I did not know that stars can create different substances and elements. #iron #nickle #whoknew #BCsci19

[Katie Hack @KatieHack13]

I find it interesting that unnecessary mass of atoms turns into energy... the world works in mysterious ways #BCsci19
