impact erosion meaning in Chinese

冲击腐蚀
冲击破裂
冲击侵蚀

I decided to add some dirt to indentations , more variety to shapes of craters , much " impact erosion " that is caused by small colliding objects and some lava rock alike features that are placed on the bottoms of fresh large craters
我决定要在低洼的地方加点儿泥土，以及更多样化的火山口外观，嗯. .还有很多由小型冲撞物造成的”撞击侵蚀”以及在年轻的大火山坑底部加上类似于熔岩之类的特征。
