I’m finished with chapters 1-7! @readysetsci

Life on Earth relies on photosynthesis!! Thank you photosynthesis!! #20BCsci

“Amino acids are the building blocks for proteins” was pounded into my head during my biology class is high school #20BCsci

I like how chapter 7 compares life’s characteristics to those of a fire🔥 #20BCsci

Its crazy to think about how long it took for multicellular life to rise on earth. About 540 million years ago, multicellular life bloomed with a huge number of new sea creatures- some of which looked like crabs or scorpions. Pretty cool! #20BCsci 🦂🦀

I wonder when this chapter was written. It talks about methane and how there is a small traces. I wonder if that’s still the case...🤔 #20BCsci

Will we ever find out what conditions are necessary for habitability? #20BCsci

Thinking about how there could have been life on other plants at one time... #20BCsci

The troposphere is 6.2 miles (10 kilometers) thick!! #20BCsci

It’s crazy to think that Venus has little to no water in its surface or atmosphere! #20BCsci

Endogenous origin vs. the Late Veneer hypothesis #20BCsci

"Liquid water was present at the surface more than 4 billion years ago, despite a hot and hostile environment". 🌊🔥 #20BCsci

It's crazy that it's harder for us to observe the inside of the earth than it is to observe other planets and galaxies. #20BCsci

I remember learning about tectonic plates in school, but like it says in the chapter, never learning why or how we had tectonic plates. #20BCsci

Does anyone else think it’s weird that Earth’s core is primarily liquid? #20BCsci

Why can’t we measure other planets seismology? #20BCsci

I’ve always been so curious about the moon, and learning about these mysteries were fascinating. #20BCsci

The planets trying to hurry up and form before the fusion started #20BCsci

If it was calculated that our Earth is 4.6 billion years old, then why are there no rocks on Earth that are that old? 🤔 #20BCsci
