The Basics of Geology: Converting a Topographic Profile into a Surface Cross Section Part 2

A continuation of the topic of drawing a cross-section from a topographic profile, this time we look how to factor in different layers of rock if they are present on a map.

Thanks for this, quite helpful. I was finishing a lab at home and definitely would have done the bedding wrong without your video

[@darkchylde3525]

what will you do if the strike and dip is not specified on one another area (e.g. if there's no strike and dip for A, will the boundary just be a straight line?)

Very helpful! Also, nice Wario Land music in the intro

Thanks! Glad it was helpful.

[@mannanali1002]

can you please tell me how to draw dip if the dip direction is N-S for this same profile? thanking you in anticipation

[@geologic7656]

The answer is simple: you wouldn't perceive the dip because it would be going into or out of the page. It's one of the issues of using a two-dimensional diagram to represent our three-dimensional world. This is why, assuming you want to show the dip of the surface, you should always draw a cross-sectional diagram in the direction of the dip.

thanks you. it really helpful.

Very helpful indeed, but just a thing I'd like to point out. In science it is good practice to ditch the imperial system and adopt the metric system... :)

[@basil6276]

true

[@anandlamdhade2350]

Thanks mate

[@skiidzman]

Wait till you gotta do the apparent dip...

[@ntumnyuygrace7723]

Sir please I don't understand that step
