The double membrane. It's theorized that chloroplasts used to be their own single-celled organism in the environment (and therefore with its own membrane). Then, the theory states, a larger cell took in the chloroplast by endocytosis, which involves surrounding the chloroplast in the large cell's own membrane. The chloroplast would then have two membranes surrounding it. This is similar to the thinking for mitochondria becoming an organelle as well. Hope this helps! :)
The process is called Erosion. During the Erosion, materials from one place such as soil and rocks will be transport to another location. The process is also contrast to the process called deposition which responsible for the control of the arrival of the materials to a new place like the rocks from Blue ridge Mountain to Virginia's Coast.
