1) Crayons
Sarah is going on a trip and is taking her art supplies with her. Her parents told her she will have to
leave them in the car during some activities. Sarah wants to keep her crayons from melting so she is
looking for the best container to place them in. What could she use as a container that will insulate
her crayons?

A). Collapse, condensation, accretion, clearing.

Explanation:

Planetesimals are described as the small solid astronomical objects which are the building blocks for the formation of solid planets. Accretion is described as the process in which the solid astronomical objects cluster to form larger objects that eventually leads to the formation of planets.

As per the question, the correct order of processes that are followed in this accretion process would be a collapse, condensation, accretion, clearing. First occurs the collapse of a nebula followed by condensation of cosmic dust grains. After this, the accession or accumulation of solid parts takes place to form larger objects and this is immediately followed by the clearing of debris and dust to allow planets to form. Thus, option A is the correct answer.
