C'mon people! We need a *lot* more questions and answers!

10 points for Gryffindor!

Next question:

An underground passage linking two cave systems follows the line of intersection of the base of a limestone bed and a vertical rock fracture. The bedding in the limestone dips 060/60 and the strike of the fracture is 010. What is the plunge of the passage?

[elephantower]

Haha let me guess: You're reading Geological Structures and Maps: A Practical Guide? I liked that problem

warning: steep passage, slippery when wet (Click to Show Hidden Text)

How steep? I get 48.07 degrees

[elephantower]

Oh, next question: A coal seam dips 4/230. The mining company wants to have passages with a slope of at least 3.5 degrees to ensure proper drainage. Give the range of possible azimuths for the passages.
Bonus points if you can ID the textbook this came from

EDIT: Or if you want a simple knowledge problem--what is an ophiolite and how are they created?

[Pupitre]

Simple knowledge questions are my specialty

Answer (Click to Show Hidden Text)

An ophiolite is some ocean crust that's been uplifted and is now visible on land, right?

[elephantower]

Right-O! Ok then looks like you need a harder random knowledge question:

<searching index, please wait>

[elephantower]

Ooh here's one: Name the 4 types of ocean sedimentary environments.
Also, what area of the rules do you need questions in the most?

[elephantower]

And another:

The above image is the map symbol of a geologic structure. What is the structure, and how is it formed?

Not entire sure if you're looking for this...

Answer(s)? (Click to Show Hidden Text)

Reef, Continental Shelf, Abyssal Plain, and Continental Slope/Rise

3-D visualizations and calculations is where I struggle the most Usually my partner's got me covered there but I wanna be able to do those problems too.

[Pupitre]

I have an answer to you're calculation problem but I solved it in a different way than my usual construction so it could very well be wrong.

Maybe? (Click to Show Hidden Text)
