Solar nebula theory explains the large relative volume of rocky material and small relative volume of ice and gases in the terrestrial planets, and the converse in the Jovian planets.

Question

Quizplus · Accepted Answer

The solar nebula theory suggests that the inner planets (terrestrial) are rocky due to their proximity to the Sun, which caused lighter elements and compounds (like ice and gases) to evaporate, leaving behind heavier materials. Conversely, the outer planets (Jovian) could retain these lighter elements and compounds, leading to their composition of more ice and gases relative to rocky material.
