How can I relate know that the amount of oxygen in the air is quadrillion metric tons? Can we make that in terms of something tangible please? #Chapter7 #BCsci18

Crazy to think that it was easier for life to exist at the bottom of the ocean rather than on the surface of the earth billions of years ago 🌍 🔥#BCsci18

If you don’t consider all three parts of the definition of living things, you might consider fire to be living! #chapter7 #BCsci18

How can I learn more about photosynthesis in one page than in all of high school? #chapter7 #BCsci18

Earths orbit around the sun is not always elliptical in shape. It transforms to a more circular shape every 100,000 years. #BCsci18

2 quadrillion lightbulbs worth of sunlight hits one side of the earth at a time 🌟 #BCsci18

The number of potential stats in our galaxy that could sustain life over a long evolution is in the billions... why haven’t we made connections with other life forms yet? #BCsci18

We only exist because liquid water existed on our planet. I guess this means I should value the water I drink since it’s responsible for my existence! #BCsci18

If Saturn’s spin is more than twice as fast as Earth’s spin, could we feel it if we were hypothetically able to stand on the planet? #BCsci18

[Catherine Castle @Cat_Castle101]

Earth’s oceans are 0.03% of the mass of the mantle.... so much for thinking the oceans were enormous in size #BCsci18

Did earth’s atmosphere have an exogenous origin or an endogenous origin? What do you think? #BCsci18

Earthquakes provide the sound source for seismology. Scientists can take an ultrasound of the Earth’s deepest structures. So does this mean earthquakes destroy, but also help us learn? #bcsci18

[Catherine Castle @Cat_Castle101]

The earth is 5.5 times more dense than water per cubic centimeter. #bcsci18

[Catherine Castle @Cat_Castle101]

Seismologists can use sound waves to learn about the interior of the earth. I didn’t know it is easier to see and learn about other planets than it is to learn the inner earth! #bcsci18

Three chapters in and we have finally made it to the death of all the dinosaurs... humans coming soon to theaters near you! #BCsci18

Our chances of dying after an asteroid collided with the earth are as high as dying in a plane crash... so why did no one warn me? Like hey, beware of those asteroids along with murders and germs... #BCsci18

Bercovici references ice skaters, dust bunnies,and the Tour de France cyclists to help us understand these concepts in space... but I’m still lost! #BCsci18

Black holes are black because light cannot escape its great gravitational force. #BCsci18
