Question

The steps of the formation sequence for a terrestrial planet are shown below. what is the correct order of these steps? - accretion of planetesimals - collapse of the solar nebula - clearing of debris - condensation of grains

Answer 1

The correct order of the steps of the formation sequence for a terrestrial planets are; 
A collapse, condensation, accretion, clearing
Terrestrial planets are formed through the process called accretion. Accretion is when the microscopic solid particles that condensed grow into planets. The microscopic particles are able to stick together through electrostatic forces and not through gravitational attraction because these particles are too small.
