Earth & Life_ONLINE REVIEW 1

During which stage did Earth form from a swirling cloud of dust and gas?

• Stage 3: A Gassy Beginning (Atmosphere Formation)

• Stage 2: Molten Mayhem (Differentiation Stage)

• Stage 1: The Early Furnace (Primordial Stage)

• Stage 4: Taking Shape (Solid Crust Formation)

In which stage did intense heat melt most of Earth, separating heavier elements towards the center and lighter elements forming a crust?

• Stage 1: The Early Furnace (Primordial Stage)

• Stage 3: A Gassy Beginning (Atmosphere Formation)

• Stage 2: Molten Mayhem (Differentiation Stage)

Which stage involved volcanic eruptions releasing gases like water vapor, methane, and carbon dioxide to form the early atmosphere?
