ACADEMIC ADVISING

Undergraduate advising in the Department of Earth Sciences is designed to allow close professional contact with our faculty and staff. Counseling on graduation and departmental requirements as well as counseling on enrollment is handled in the Department Office by the Student Affairs Officer.

Each major will select a faculty mentor who will counsel the student on career goals and research opportunities. The department recommends that each student meet with their faculty mentor at least once each quarter to clarify career objectives and revise the program of study so it is commensurate with the developing interests and objectives of the student.

TEACHING CREDENTIAL

Teachers in the public schools in California must have a credential approved by the State Commission on Teacher Credentialing. The credential requires an undergraduate major, baccalaureate degree, and completion of a graduate credential program such as that offered by the School of Education at UCR. The latter usually requires three quarters and includes education courses and supervised teaching.

Before admission and student teaching in a graduate credential program, the candidate must pass the California Basic Education Skills Test (CBEST) and demonstrate subject-matter proficiency in the fields which the candidate will teach. The candidate can demonstrate proficiency either by passing the Commission's subject-matter assessment examination, or preferably, by completion of an undergraduate program that is state-approved for teacher preparation.

UCR has an approved undergraduate program for earth science majors who plan to get a Multiple-subject Credential and teach in the elementary (K-6) grades. A breadth of course work is necessary, in addition to those required for the major. Students are urged to start early, preferably as freshmen, selecting courses most helpful for this career.

UCR does not yet have a state-approved undergraduate program for earth science majors who wish to teach at the secondary level. The Teaching Credential in Science, geoscience emphasis, is required for geoscience teachers, grades 7-12. Students who plan to get this credential must take the Commission's subject-matter assessment examination and should make certain their academic program includes preparatory course work. The examination includes geoscience in depth and general science with introductory, college-level biology, chemistry, physics, and geoscience (geology, meteorology, oceanography, astronomy).

Further information about courses, requirements, and examinations can be obtained in orientation meetings, the Student Affairs Office (1432 Geology Building), and the School of Education (1215 Sproul Hall).

GEOGRAPHY MAJOR

The Geography Program offers two options for students who have a broad interest in Earth surface systems: Biogeography and Geomorphology. Spatial and temporal variations in physical phenomena and human activities, their interactions, and the processes producing spatial distributions are major concerns of geography. Geographers study such topics as climate and climatic change; processes in the evolution of landforms; ecology, distribution, and conservation of plant and animal species; the human use of the natural environment; and processes of urban growth and decline.

BIOGEOGRAPHY OPTION

Students fulfilling the Biogeography option study the distribution, structure, dynamics, and conservation of natural communities and ecosystems. Biogeography has foundations both in biological and earth sciences. The biogeography of species is studied to determine evolutionary and dispersal history over long time scales (see paleontology under Geological Sciences, below). Geographers investigate local and regional distributions in relation to the contemporary environment and impacts by people. Biogeographers also examine strategies which attempt to protect ecosystem and species diversity by integrating ecosystem management into human-impacted landscapes. Students in this option receive training in ecology, vegetation analysis, resource conservation, and management of natural lands.

GEOMORPHOLOGY OPTION

Students who choose the Geomorphology option study the nature and spatial pattern of landforms in relation to tectonics and the contemporary physical processes of weathering, erosion, and deposition. The ages of land features are evaluated to infer erosional and depositional histories and their relationship to climatic and tectonic change. Students who undertake this option obtain practical training in the evaluation of natural hazards in relation to land use and planning.

GEOLOGY MAJOR

The department offers two options for the Geology major: General Geology and Paleontology. Students who choose the Geology major study the structure, composition, and history of the earth, and in particular, it's crust--the earth's immediate surface and underlying rocks. Geologists examine rocks and minerals in order to formulate and test theories on natural processes affecting the earth and to explore for mineral resources. They may also study fossil remains of animals and plant life and observe the flow of fluids and gases through rocks to determine the ages and rates of change of various parts of the earth's crust, as well as the possibility of oil and gas deposits. They contribute to environmental impact studies by examining the effects of wind,water, earthquakes, landslides, or volcanic action on landforms. Geologists also determine sources of groundwater and possible contamination effects.

GEOPHYSICS MAJOR

Students who choose the Geophysics major apply the principles and concepts of physics, mathematics, geology, and engineering to the study of the physical characteristics of the earth and other planets. They make measurements of gravity and magnetic fields, seismic waves, temperatures, and natural electric current. Geophysicists study these topics from the standpoint of the physics of solid bodies, gases, and fluids. Some geophysicists are field oriented, some laboratory oriented, some theoretical, and some combine these areas.

DEGREE REQUIREMENTS

UNIVERSITY REQUIREMENTS

General University requirements are Universitywide requirements which all undergraduates must satisfy. See the Undergraduate Studies section for a complete listing.

COLLEGE REQUIREMENTS

Students must fulfill all breadth requirements of the College of Natural and Agricultural Sciences. See Degree Requirements under College of Natural and Agricultural Sciences in the Undergraduate Studies section of this catalog.

Some of the following requirements for the major may also fulfill some of the College's breadth requirements. Consult with a department advisor for course planning.

MAJOR REQUIREMENTS

GEOGRAPHY

In both lower- and upper-division courses, the curriculum in Geography provides an overview of the earth sciences. Students are required to take an analytical course series in remote sensing and geographic information systems, which have become essential tools in geographic research. Students must also develop complementary background in either statistics, computer science, or calculus. Usually by the sophomore year, students must have selected a curriculum option. In each option, students must fulfill required and elective courses from outside the major and within upper-division Geosciences.

The following are the requirements for the Bachelor of Arts and the Bachelor of Science degree in Geography. Students must complete the core requirements and choose one option.

GRADUATE PROGRAMS IN GEOLOGICAL SCIENCES AND IN GEOGRAPHY

The Department of Earth Sciences offers degrees in Geological Sciences and in Geography. Graduate education in the Geological Sciences emphasizes general geology combined with specialization in fields such as applied geophysics, geotectonics, crustal processes, geochemistry, petrology, geothermal resource investigations, groundwater, mineral deposits, stratigraphy, sedimentology, basin analysis, carbonate diagenesis, evolutionary paleobiology, invertebrate paleontology, Quaternary geology, and neotectonics. Graduate education in Geography emphasizes geomorphology, neotectonics, landscape ecology, fire ecology, natural resource conservation, locational analysis, transportation modeling, quantitative geographic methods, including GIS. In both degrees, integrated field and laboratory studies are encouraged. An undergraduate degree in geology, geophysics, geochemistry, or geography is the normal preparation for graduate work; however, a degree from a related field of science or engineering is often appropriate. Applicants to graduate status must supply Graduate Record Examination scores for the General Test (verbal, quantitative, analytical) prior to their admission.

MASTER'S DEGREE

M.S. degrees are offered in Geological Sciences (with emphasis in Geology or in Geophysics) and in Geography. The normative time to a master's degree is seven quarters. In addition to the general requirements listed under the Graduate Studies section of this catalog, the requirements for the M.S. are as follows:

1. A student is required to make up any deficiency in preparation. The background required is course preparation equivalent to the bachelor's degree in Geology, Geophysics, or Geography at UCR. Courses taken to remedy background deficiencies are not applicable to the graduate degree. Such courses will be designated in the letter of admissions to the program sent to the student by the Dean of the Graduate Division.

2. Biannual reviews by the departmental Graduate Progress Committee are required for all students. A student's progress is assessed in these reviews, and the Committee may recommend changes in a student's plans after these reviews.

3. All students must enroll each quarter in the Graduate Seminar in Geosciences (GEO 250). Students are also required to attend the weekly Hewett Club lecture series.

4. In both Geological Sciences and in Geography, a minimum of 36 units of course work in the major and related subjects and advance approval of a coherent plan of study by the graduate advisor are required.

A maximum of 12 upper-division units beyond the requirements for the bachelor's degree may be applied to the 36-unit requirement. A minimum of 12 units of graduate courses, which must include at least four graduate-level instructional courses taught by four different faculty members as approved by the graduate advisor, are required. Before the end of the third quarter of study and before embarking on research, a student must submit a written thesis proposal to the departmental Graduate Progress Committee. After approval of the proposal, a thesis based on original work must be submitted to and approved by a thesis committee. A maximum of 12 units of thesis research may be counted toward the 36-unit minimum.

5. A final oral examination will consist of an open research seminar, presented by the candidate and advertised to all the students and faculty in the Earth Sciences Department.

Subject to the approval of the graduate advisor, a limited number of upper-division courses in the major and related sciences, if not required for the bachelor's degree and not taken previously, may be accepted for graduate credit.

DOCTORAL DEGREE

In addition to the general University requirements of the Graduate Division as found in the Graduate Studies section of this catalog, the Ph.D. in Geological Sciences and in Geography normally requires

1. Biannual Reviews. All students meet with the Graduate Progress Committee during their first week at UCR to discuss general interests, goals, and plans. The committee will recommend courses designed to prepare a student for research and to correct deficiencies in background. This committee will also review a student's progress biannually and may recommend transfer to the master's program if normal progress is not maintained.

2. All students must enroll each quarter in the Graduate Seminar in Geosciences (GEO 250). Students are also required to attend the weekly Hewett Club lecture series.

3. Course Work. At least four graduate-level instructional courses taught by four different faculty members as approved by the Graduate Advisor are required. Course work used in satisfaction of the M.S. degree may be accepted with the Graduate Advisor's approval.

4. Language. Depending upon the student's proposed area of specialization, the student must demonstrate reading knowledge of a foreign language or facility with a computer programming language. In consultation with the student, during the first year of graduate studies, the Graduate Advisor and potential dissertation advisors will determine the language that will be required.

5. Research Proposal. A research proposal must be written by the student while satisfying course work and language requirements. The proposal will be examined by the faculty and, if acceptable, the Department will recommend appointment of the Oral Examination Committee once all other requirements are completed.

6. Oral Examination. An Oral Examination Committee appointed by the Dean of the Graduate Division will examine the adequacy of the student's preparation to conduct the proposed research. Advancement to candidacy in the Ph.D. program follows successful completion of the oral examination.

7. Dissertation. A dissertation normally evolves from the research proposal. The dissertation must present original scholarly work and be approved by a dissertation committee before the student may take the final oral examination.

8. Final Oral Examination. Satisfactory performance on a final oral examination given by the dissertation committee is required. Major emphasis in this examination will be placed on the dissertation and related topics.

Normative time to the Ph.D. degree from the B.S. degree is 17 quarters.
