Answer :
Final answer:
Gravity and density differences of materials are the primary factors responsible for the inferred layered structure of planets in our solar system.
Explanation:
Gravity and density differences of materials are the two factors that caused the inferred layered structure of planets in our solar system. Gravity plays a key role in the differentiation process, where the heavier materials sink to form a core and lighter materials rise to form a crust, creating distinct layers. This process is essential for a planet to develop a layered structure based on its material composition.
