Thread: How the hole in the river in the stage f upstream?

same with topic...

To be honest I have no idea what you are asking, could you please elaborate/clarify?

James, you have now posted several questions on the forum. As far as I can see these questions have two characteristics:
1) They are very basic.
2) They are very badly phrased.

From this I deduce you are a) a high school student, b) English is not your native language.

Several of us have replied to your questions. (It would be nice to know if the answers were helpful.) It would help us to answer more accurately if you could try to write the questions more clearly and if you could tell us what you think the answer might be. Like Paleoichneum I have no idea what you are asking in this thread.

James, we don't have access to your homework questions, so even if we wanted to help you avoid doing the proper study, we simply cannot answer a partial question ... especially one which relates to a specific diagram ...

There are rules and guidelines about study questions for good reason - getting someone else to do your homework or assignment is considered cheating by every school ... and the value of learning is lost ...

We can help you understand the principles and practices in general terms, and we can relate these to other examples, but we cannot (or will not) cheat for you ...

I say:"this is not my homework!"
I want to know how to form only..
if this is m homework...i can ask my teacher!
and my english is not well...

and i not a high school student...my text book explains not clearly...i want to know and ask anybody.....is this a wrong?

There are many holes(deep part of river) in the river in the upper course of river.......
but how the hole in the river forms?

OK - you're not a high school student (but you are using a textbook), and these questions are not for homework, but to understand what your textbook is saying ...

How the hole in the river in the stage f upstream?

This is the question in the title of the discussion -
which doesn't show up when I try to reply, by the way, so that all I have to refer back to is: "same with topic".

First, can you tell us the name of the textbook you are using, and what page you are trying to understand?

Then can you copy exactly what is in the textbook about the "hole in the river"?

Can you describe the diagram or picture*, so that we can understand what the book means by "stage F"?

*ETA: There may be more than one - a series of diagrams (or descriptions), one for each stage ...

OK -

Do you understand how the gradient (in this case the slope of the terrain) affects the natural flow of water, and the profile (shape across the river course) of the riverbed?

Have you looked at the differences between laminar and turbulent flow yet?

Do you have information about the geology, or even the geography, of the upper reaches - ie, mountains or plateau? (usually mountains)

Have you studied how different mountains form - what sort of rock layers you can expect to find, and at what sort of angles the layers might be found?
