英文小作文：

The process of accretion is essential in the formation and evolution of our planet. It is a fundamental aspect of the formation and growth of mountains, oceans, and even entire planetary bodies like the moon. Accretion occurs when material accumulates around a larger object, usually due to the movement of sediment or other particles, and gradually adheres to it, forming a new layer or wedge. This process can be observed in various environments, from the mountains formed by the accumulation of rocky material to the oceans that are constantly accreting new islands and seamounts. Accretion is a continuous process that shapes our planet and contributes to its diversity and beauty.
