How does accretion add to the surface area of a continent?

The surface area of a continent increases due to the rapid accumulation of sediments. The more is the sediment amount deposited, the more is its area. This particles gets deposited due to the weathering and erosion of the rocks at different places by the agents such as air, water and wind.

In addition to that, the converging plate movements also helped in increasing its height and area.

Thus, this processes adds the materials to the total continental crust, thereby increases its surface area.

what's the rest of the question

"it built up in the atmosphere"

i think thats it, idk, i tried looking for this exact q& a for grad. and idk if i got this question right or sorry if im wrong
