Lecture 3 - History of Planet Earth - ESM 120 (Winter 2021)
From Rebecca Hernandez on January 12th, 2021
Lecture 3. Carl Sagan once stated, “We’re made of star stuff.” Today, we are going to discuss why that phrase is 100% true. This lecture, we will discuss a brief history of our planet beginning with a bang – the big bang. We will explore runaway greenhouse effects, the habitable zone, the cosmic abundance, the molten, hot early Earth, the differentiation of Earth into layers – and like always, we will focus on identifying the connectedness of systems and processes.
