Question

what was the significance of collisions of dust, rock, and ice during earths formation? to modify the density of materials present on earth to facilitate heat absorption from the surrounding space to blow away a strong burst of particles from the first atmosphere to harden materials to form different parts of earths layers

Explanation:

During Earth's formation, collisions of dust, rock, and ice helped to harden materials to form different parts of Earth's layers. These impacts provided energy and pressure that contributed to the accretion and differentiation processes leading to the formation of the core, mantle, and crust.

Answer:

to harden materials to form different parts of Earth's layers
