GEO4311 GEOLOGY COURSE PROCEDURE


GEO4311 GEOLOGY

5 Credit Hours

This course is open to students on the college level in either the freshman or sophomore year.

Catalog Description of the Course:

GEO4311 - Geology (5 hrs.) 

[KRSN  PSI 1030]

A study of the geologic features of the surface of the earth, and the processes, which have produced them.  Laboratory work includes identification of rocks and minerals and the use and preparation of geological and topographical maps utilizing the scientific method.

Course Classification:

Lecture / Lab

Prerequisites:

None

Controlling Purpose:

This course is designed to give a background in the field of geology for students planning to enter the fields of agriculture, soil mechanics, civil and mechanical engineering, architecture, earth sciences, other physical sciences, and biological sciences.  In addition, it is designed to meet the needs of other students who wish to know about rocks, minerals, and geological structures and how they were formed.

Learner Outcomes:

Upon completion of this course, students will be able to identify common rocks and minerals, to interpret and analyze the geology of an area in simpler cases, and to identify geological structures and their causes.  In addition, the student will be able to use and to prepare geological and topographical maps.

A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time,  The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
