CH 7: talks about the characteristics and elements of life. Most of earths biological history was occupied by microbes. The end of the snowball state led to the Cambrian explosion, and plants/animals happened about 400 M years ago. #BCsci19

CH 6: talks about why the earth has the climate that it does. The conditions of our planet are perfect for life to exist. Weathering and erosion are effected by the temperature of our planet as well. #BCsci19

[Hope @In_S_P_I_Re]

CH 5: looks at different planet's atmospheres, the effects of asteroids on our solar system, and explores different theories of how earth's oceans and atmospheres came to be. #BCsci19

[Hope @In_S_P_I_Re]

CH 4: looks at how earth's interior came into existence. We can study earth's interior using seismology, and we know the earth is protected by a magnetic field. #BCsci19

[Hope @In_S_P_I_Re]

The first forms of life could've been formed in the bottom of the ocean where they would've been protected from the hostile earth environment. This would make sense! #BCsci19

Hydrogen came from the Big Bang, but carbon, oxygen, nitrogen, and phosphorus comes from stars. Interesting! What about all the other elements? #BCsci19

[Hope @In_S_P_I_Re]

Nucleotides make molecules that store and carry out energy like ATP. I remember this being important in AP bio. #BCsci19

[Hope @In_S_P_I_Re]

We know there is carbon in the mantle because there are diamonds in the mantle... bling bling #BCsci19

[Hope @In_S_P_I_Re]

Thank you earth... for your habitability.... and for not wiping us out every few million years or so. #BCsci19

[Hope @In_S_P_I_Re]

I remember learning about the Goldilocks effect in astronomy. Not too hot... Not too cold... The earth is placed at a perfect distance away from the sun. #BCsci19

[Hope @In_S_P_I_Re]

Me when I read that our atmosphere is only like 20 percent oxygen #BCsci19

[Hope @In_S_P_I_Re]

Earth had a more powerful greenhouse effect. Take that Venus!!! #BCsci19

[Hope @In_S_P_I_Re]

It doesn't take much melt to extract volatiles from the giant mantle to make the oceans and atmospheres. Cool! #BCsci19

[Hope @In_S_P_I_Re]

I still don't really understand why tectonic plates move #BCsci19

[Hope @In_S_P_I_Re]

Tectonic plates remain a mystery that is still being researched #BCsci19

[Hope @In_S_P_I_Re]

It's crazy to think that the mantle is still hot from its early days after the magma ocean froze. #BCsci19

[Hope @In_S_P_I_Re]

The mantle makes up more than 10 percent of Earth's entire volume. #BCsci19

[Hope @In_S_P_I_Re]

The Earth is 4.6 billion years old, but there aren't rocks on Earth that old to date. #BCsci19

[Hope @In_S_P_I_Re]

Most of the mass in the solar system is from the sun and Jupiter. Foreal?? #BCsci19
