How Shanghai Was Formed （1/4）
Shanghai is located on the eastern coast of China, facing the Pacific Ocean to the east.
It is bordered by the East China Sea in the east, Hangzhou Bay in the south, Jiangsu and Zhejiang provinces in the west, and the Yangtze River mouth in the north. It is part of the flat plain formed by river deposits in the Yangtze River Delta, with the terrain sloping gently from west to east (higher in the west, lower in the east). The whole area is a plain except for a few hills in the southwest.
Over the past 20,000 years, the Yangtze River mouth has gradually evolved from a giant stepped slope descending gently toward the east into a flat river-deposited plain, as a result of river and ocean erosion and deposition.

Thank you!
I've learned a lot from several friends here.
Have a nice day!

Since Shanghai is a city, I would expect this series of posts to talk about the social process that led to the founding of the city.

As another corrector has noted, “to the east” is redundant.

It is part of the flat plain formed by river deposits in the Yangtze River Delta, with the terrain sloping gently from west to east (higher in the west, lower in the east).
The parenthetical part is unnecessary, since “higher in the west and lower in the east” is exactly what “sloping from west to east” means.

Over the past 20,000 years, the Yangtze River mouth has gradually evolved from a giant stepped slope descending gently toward the east into a flat river-deposited plain, as a result of river and ocean erosion and deposition.

I’m not sure what level of correction you are looking for here. This sentence is grammatically correct, but I don’t think it works logically. I’m assuming the basic structure of this sentence is supposed to be “the river mouth has evolved from A into B,” but this doesn’t make sense to me, since the river mouth couldn’t have evolved from a giant stepped slope into a flat plain (because, by definition, the river mouth has always been at the edge of the sea, so it can’t have been either of these two things).
Sorry, I guess I just don’t understand what you’re trying to say.

把 river mouth 换成 terrain in the Yangtze River estuary呢？

把 river mouth 换成 terrain in the Yangtze River estuary呢？
No, I don’t think “estuary” would work, either.
Is the purpose of this sentence to describe how a river delta forms? I.e., “the Yangtze River flowed down the stepped slope for thousands of years, carving into it and depositing silt where it met the sea, gradually forming the wide, flat Yangtze River delta”?

Over the past 20,000 years, the Yangtze River flowed down the ancient stepped slope, depositing silt where it met the sea and gradually forming the flat Yangtze River Delta.——这样可以吗？
太感谢你的持续反馈了。感觉一下子体会到了estuary和river delta在具体事物上的区别。estuary是入海口，也就是现今长江在上海崇明岛入海的那部分；river delta，就是长三角陆地，长江冲刷出来的土地。因为我在写上海这块陆地的形成，所以就应该用river delta，是这样的吗？

Yes, I think so (in answer to both questions).

"East" is already implied by "eastern coast", so you can drop it here to avoid the repetition.

I had this point in mind while writing, but wasn't entirely sure. Thanks for confirming!
Have a nice day!
